Yes, good. Wha. Good day, Sir.

Please start by introducing your professional journey in academia.

And after that I have done my masters of technology from in the branch of power systems from Technocrats Institute of Technology under RGPV. And recently I have completed my Doctorate of Philosophy PSD from Maulana Azad National Institute of Technology, Bhopal. And my specialization during PSD was the fuel cell and coming to my professional professional.

Uh so I I have done my Btech from the Lion state of technology Durg in the year 2011 in the branch electrical engineering.

Experience I have I have a teaching experience.

Of more than seven years, which out of which for six years is after Mtech and the, the, the two years are before Mtech. And recently, after completing my PhD, I have joined GL Bajaj Institute of Technology and Management, Greater Noida as an assistant professor in the department of Triple E and I'm teaching there, uh, the basic electrical engineering subject in the 1st.

So during my professional experience, I have done uh, various works related to uh accreditation and also in the academic field. Like I have uh, taught students. I have also done uh, the, the examination works, the curriculum design. I have done all these things and the next coming to my research experiences, so I have UH-5 journal papers.

And in this journal papers I have three Sci's published and two Scopus published and four of my Scis are in under revision stage. So this was my academic profile. And now coming to the IP intellectual properties, I have 3 design grants in my name, 2 patent publication out of which one is under examination and other one didn't reach 2 examination.

15 conference, 13 conference papers and three book chapters.

So this was my professional journey.

Thank you for sharing that, Professor.

Yes, Sir.

Hello.

Hello, Sir.

Yes.

Hello, Professor Mitra.

Let's begin, Professor Mitra. Could you elaborate on your experience in guiding student projects or research in the field of renewable engineering?

Uh, so, uh, I have, uh, experiences in guiding B.Tech students. So in the field of renewable energy, my, some of the B.Tech students, uh, which I have thought they have basically done their work in a hybrid engineering, hybrid, uh, hybrid power systems where they have combined the wind, wind along with the, uh, solar systems. So, uh, basically what I have done is I have taught them how.

Using hybrid systems are buying with the, uh, how with the help of hybrid systems, they can share the load in DC migrate. As you can see that renewable energies are very important nowadays due to the increasing energy demand. Also, there are certain, certain students like I have only guided the BTEC students. Uh, till now I have, I have not guided any of the Mtech projects as a faculty, but as a PSD scholar, I have guided an Mtech scholars. So one of my, uh, I have assisted guiding the Mtech scholars. So one of the scholar he have worked in the area of fusion where he had used the fuel cell for power generation which he has supplied which which the power generated from fusion has been supplied to a DC route. This was done by one of my scholars in the Mtech. And the second scholar his work was in electric vehicle area. In that area he was he had done the charging from the grid. He has used the he he has charged the. We from the grid. So this was his area in the in in his Amtech and some of my students since my specialization was in fusion during PhD. So one of the best they have done their project in a fuel cell in the area of fuel cell electric vehicles where they have used the power generated of from fuel sun to for as a supply to the vehicles like you can see nowadays in India also.

We are using hydrogen vehicles. So there the students have used the fuel cell as a as a running, running main source for running the vehicle. So this was all from the area of renewable energy supply. But there are also some students like in their projects they have used, they have, they have used the temperature sensors and Iot's are also used in this purpose.

Yes, yes, Sir.

Could you clarify how you incorporate theory and laboratory instruction to provide a structured and comprehensive learning experience for your students in engineering courses?

Uh, so like, uh, we, uh, suppose, uh, like there's a subject which I have been teaching not now only from last so many years, I have taught they like start from basic electrical engineering. So in basic electrical engineering, as you can see, we are, we have been thought a lot of theorems, like you can see Thevenin's theorem, Norton theorem, Kirchhoff's laws, uh, Ohm's law. So what we do, we teach them this in the, in the, in the classroom, and then we demonstrate it in the.

Showing them how they are, how whether this theorems are real or not means whether these theorems are true or not. So with the help of laboratory experiments, we, we, we basically teach the students this experiments are true or not. Now coming to other experiments like there are certain certain open test in Transformers, you can say open circuit test, short circuit test. Now what the students study in the classroom, they have been thought the same in the.

In their laboratories in the experimental form means there are Transformers where they can perform this and after performing this they will come to know that what they have taught in the theory is right or not. Now suppose coming to the renewable energy sector means in the renewable energy. What we have done is we can we usually study that there are the the solar is the solar panels, PV panels are converted are connected to the converters and. This the power generated from the convert the.

We plant is going through the converters. So this type of all the things we are studying in the papers. So which we which we you can say simulate in the MATLAB section in or any or any of the software platforms, designing platforms. This are the theoretical part or the simulation part. So how we are going to know that what it is whether it is actually existing or not. So there are panels like where I have studied the PhD or my graduation.

So there I have seen there are panels. So there you can see that what we are studying, we are going there and we are taking the students to show that what you heard getting taught in the class or what you are getting in the papers, you can get it. You can see it in the real time experiences in the PV panels. You can see the the generation which is used somewhat somehow some of that is used in your buildings and the rest which is excessive is supplied to the grid. So this is how.

We teach to the students related to your theoretical subject or the research. Other than that, there are basis students doing the project works like there are students like. You can see the dustbin, IoT based dustbin. These are also the projects where we have guided the where I have guided the students, I have to build the screen or the farthest the the the means the fire, the fire detection alarm or the gas detection sensors. These are all the IoT projects. There's a temperature detection in Transformers. So apart from the.

Allergy. These are all the all the what I missed. These are all the projects where I have guided the students how they can, how they can perform this, how they what they are learning or what they have seen in the theory or in the papers, how they can, how they can see it in the real time or how they can perform it.

Yes.

Could you now discuss one of your significant research publications, particularly focusing on its contribution to the field of renewable engineering?

OK, uh, Sir, Lisa, as I have told that my, basically my, my PhD work is in the area of fuel cells. So, uh, my significant research, one of my significant research paper is the, is a review paper. Although it's a review paper, it is the parameter literatures, comprehensive and comparative literature review on the parameter estimation of fuses. Where I have, uh, I have, where I have compared, I have shown all the literatures, uh, related to parameter estim.

And I have compared them so that the researchers are researchers can discuss which which methods they should use or knows not. And this paper was published in the journal fuel, which is having a which is a fuel which is of elsewhere and having an impact factor of 8.05, which was a review paper. But now coming to my one of the my. My research paper So the research paper, the research paper is basically my next research paper is an Indian journal of Chemical Society which relates the DC fuel cell integration to the DC microgrid. So the fuel cell integration to DC microgrid, I have explained that how the the the the optimize the parameter optimization I have done to a particular commercial solution how that that optimize the fuel cell is been integrated to DC microgrid and is it.

Delivering to the DC nodes, this is my second research paper but which has been which has been published recently before some weeks and it is having an impact factor of 3.4 and this both the papers I feel that they give an impact they have an impact on the society like since the hydrogen is one of the most promising fuels green fuels of nowadays. So this. This is how this this is useful.

Further for the current society, so these are two of my CIS. There are other Scopus paper which also discussed the parameter estimation of commercial fuels using different methods. They are also been published in other journals like Environmental Science and Pollution Research and that Springer, Nature, Computer Science and one of my papers which we have paid which we for which we have applied for patent it is. It is on a multi railways multi track system where we have used an electromagnetic.

Switching control for multi switching tracks in the railway. So this one is also the part it is different from my area of renewable energy. But this paper is also highly, highly useful for the society as the transport is a very high transport is very important aspects of the day-to-day life.

Your research contributions provide clear insights into the utility of renewable energy systems and their application, particularly with hydrogen fuel cells and microgrid integration. Thank you for elaborating on your impactful work.

Thank you, Sir.

Yes, yes.

Could you elaborate on any experiences you've had with industry projects or consultancy, particularly in the context of renewable engineering?

Uh, sorry to say, Sir, I have no industrial collaborations or, or corporate means no industrial consultancy or collaborations in this area. But recently I'm writing projects so that to gain any insights from the, I'm trying to collaborate with the companies, the, the startups which are working in the area of solar and fuses. So, so to gain insights from the real time area, but right.

Now I don't have any industrial collaborations or project but I am writing them so as to get them in the near future.

Understood, Professor Mitra. While industry collaboration is an ongoing pursuit, it's good to recognize your initiative in writing such projects for future opportunities.

OK.

Now, can you share how you ensure effective evaluation of students, particularly in exams or other assessment methods?

Your marks or not only the class performance is a is a maximum for assessing the student. It is a collaborative work. So for assessment, I not only not only depend on the marks which we which they obtained in the exam, I also see their class performance for suppose which I have taught up, I have taught up. Torture topic and I want their their feedback. So I would I would I would take a quiz for them so that they would I can know how much they have understood. If there are numericals possible, I would give them numericals for the same and likely in that cases. Means like if I am going for the evaluation, like for an end term examinations they are having and if some students score less so they will be asked to if they have day out they can come to us and they can ask.

So like I, I particularly believe that not only.

And for how much they are going to understand that well. And well, for that we will, I will be engaging, I will have some engaging talks or I will be giving them some tasks or assignments so that they could easily, easily understand that topic. And after that they could deliver me properly. So, so for this, this is a particular process of evaluation which will take time. So how I evaluate, I evaluate them starting from their how they perform in the class after that.

Their performance is their performance linked to their their return assessments like in the semester exams or theory exams and after that how they perform. After the seeing their performance in their tests and before their exams, we will be having a long discussion or an or some presentation classes where their doubts or their problems which they are facing will be discussed.

Your approach combines continuous assessment, individual engagement, and problem resolution, demonstrating a structured and student-focused evaluation methodology. Excellent.

Thank you, Sir.

Let’s now discuss your teaching approach. How do you ensure your communication and teaching methods are effective and well-structured for your students?

So, uh, like, uh, for, for suppose we are starting a chapter. So I, I basically think that, uh, me the student, it is not necessary that student know each and everything. So while, uh, starting the chapter or while starting a topic, uh, all the things which is related to this topics, I used to ask them in those topics are clear to those students means they are in a state to understand the future of this topic Mr.

Topics in the in that chapter which are a bit advanced to the basic topic. So first I ask them if they are aware of those things, then we move forward. And with that, with that topics, I am not only like we are just going through, I will take the topic it is a theory. Then I take the numericals of that topic so the students are in in line with that topic and I I specifically I believe that.

The topics could be covered or the unit should be covered. Should be in a.

A synchronized manner so that the students don't get confused for now as well as the earlier semester. So what my approach is, I start with a basic topic of the of the unit and ask them whether they know that topic related to the given syllabus. After I am assured that they are aware of the problem, aware of the topic, then only I, I, I start, I go forward and if I see they are not aware of the topic then I make them understand that.

The particular topic which is related to the which is the base of the chapter. So this is how I use I deal with a certain chapter or certain topic and the rest of the things is like the whole syllabus. I try to cover the topics which which are the which would be toughest to the students. But my major focus is how much knowledge they get in the particular class. That should be sufficient means that should be means for that they are confident.

Much more, they feel themselves strengthened, strengthened that they can write those topics or they can solve the questions easily without any hesitation in the papers.

Thank you, Sir.

Your approach emphasizes foundational understanding, synchronized progression, and building student confidence, which are key aspects of effective teaching. Thank you for outlining your structured methodology.

Sir, I basically think that the the classroom setups nowadays, there should be a visual, the visual technique which which should be because of visual techniques helps students to select what I am teaching. If those students see those in like smart TV's or smart classroom which have their TV's. So I basically feel is what I am teaching, they should visualize that at the same time which will help them to remember it for a long time. Even though it's like for suppose I'm, I'm teaching about them about how solar work, how they look, what are the types? At the same time, if they see, if they visualize it or if they can see it in the in the classroom, maybe through the monitor or maybe I can show them through the presentation or through some video, then it will be possible. It will be very much helpful for them to remember that that and to understand that approach easily. So it will not be burden for them means for each aspect like for renewable energy we are saying that we are generating.

Professor, to start, could you tell me about a specific teaching environment or classroom setup you find particularly effective for engaging students in the fundamentals of renewable engineering?

Powers with the help of converters and inverters and controllers. We are, we are, we are using it to to feed the load. So this whole process if they see if they visualize it in each and every step, if it is easy for them to explain and say, then it will be easy for them. So as per my my thinking and my belief, the visual experience or the visual teaching form is the best for the students in the classroom as it is easy for the faculty as well as.

Students to explain and understand at the same time by seeing and logically thinking each and every aspect.

Thank you, Sir.

Thank you, Professor, for elaborating

Professor Mitra, I see you have a well-decorated academic background with a focus on renewable energy. I noticed your award-winning paper, *Comparative Analysis of Hybrid Electric Vehicle on Different Performance Metrics using ADVISOR 2.0*, caught significant academic attention. Could you elaborate on the core findings of this research?

So the core finding of this research suggested that this research was basically using a software that is Advisor 2.0 which was designed in the USA. So this Advisor 2.0 shows that means what we have done there are four different types of vehicles. One was a few we have taken as a fuels that normal vehicle which is your the conventional vehicle. Second was the purely electric vehicle. Next was the fuel cell hybrid electric fuel cell electric vehicle.

And the fourth was completely hybrid electric vehicle. So we have compared this all the vehicles on the term of the mechanical parameters as well as on the basis of their torque, their power and generation, how much noise, how much they are affecting to the environment, the all the fuel cell consumption they are torque related to their miss, what you can say related to their power and all these things we have compared and how much cost they.

Getting this all things were compared means there were certain parameters mentioned for each of the vehicle, each of the vehicle and we have compared all the vehicles on those certain parameters to find out which vehicle was the best. Although we have seen that electric vehicles was was better in each and every aspect but there are also something comes like charging infrastructure because now also there are various countries which are not having a proper infrastructure for electric vehicle as they are.

Right now, so, uh, skipping that in mind, we have seen that hybrid electric vehicles are better because those hybrid electric vehicles, they not only work on the electric electricity, but they also work on the same side. They also work on the, uh, conventional methods, which are the petroleum or the conventional form of sources. So, uh, on the various parameters which were suggested, uh, which were, uh, a panel were designed in the advisor for every such panel, we have to, we have put the.

The the vehicle which like for hybrid electric vehicle we have taken someone, we have for EV, we have taken some commercial. So like this way the advisor software, it compared the all the parameters and and by after analyzing the results we came we came to our our result. Although electric vehicle is the best option, but for for conscious developing under hybrid electric vehicle is at par the best now.

Thank you, Sir.

How did you ensure that this study's findings could be effectively communicated to students, particularly those new to these technologies, in a classroom setting?

Uh, Sir, like, uh, for, if you say about renewable energies, so like I have said, fuel cell it, it is a green technology. So like, uh, in this case, I can say the students, how they are related to that, that particular topic, how this topics means in the class, I can say them how the conventional, what are the, what does, what the findings I got in conventional, conventional vehicles, What findings I have got in electric vehicles, what in fuels and what in hybrid electric.

On the basis of that we, I can tell my students which we are better and in the basis of that for which approach they should they should opt for. Like you can see that in case of EVs there are a lot of improvements within. Now the EVs have been charged using the the renewable energy sources. There are some vehicles you can see which uses solar rooftops, solar rooftops for their sources. So this all things can be tell me can we? Taught in the class to the students.

So that they can get the understanding and on the basis of that, they will also be able to analyze it. What is the better and what what what more recent are what are the recent trends to the existing literature or to the MI existing research paper?

So, uh, like, uh, I can, I can ask them, uh, if we take, I can say them that in the real time scenario, suppose there are 10 to 15 electric vehicles, I would ask which vehicles they have seen and what, uh, they can, uh, since we are having a lot of online datas of the certain various vehicles, so I can ask them to, they can, uh, to, to compare all these vehicles, unlike like I have said that the fuel sun is trending nowadays, so.

Understood, Professor Mitra. How do you plan to encourage students to critically evaluate such findings and develop their own research questions in this rapidly evolving field?

I will ask them to relate these things and I will ask them to see the performance. Like you can see there are a lot of data which is available online which will say you what what is the average of the average mileage of the of the vehicles in the electric case, in the conventional vehicle case, in the fuels or vehicles or in the hybrid vehicles. So I will let them know. I will ask them to prepare a comparative analysis which they will evaluate and they can let me know. So due to this, they will also come to know.

But what are the defects and what are the what are the best, what are their best, what are their pros and what are their cons? They can write them. So after evaluating the best method, we can send them to to research more and more on them. Like you can see the fuels in hybrid electric vehicle. Although it is very much favors in the European countries, but in India it is still it has it has been introduced but it has a long way to go. So like this only I can ask them to see.

Better to analyze them then studies more and more data on them and then to form or then to perform research for the new topics or the for the new discoveries. And what are the best methods which can be introduced in them to make their performance better through simulation or through modeling?

Thank you, Sir.

So, uh, if I, if you ask me about 3, my three-year research, uh, planning. So, uh, my first plan, uh, of this, I have been planned from 2026. I am basically seeking for a project in the field of fuel cell, uh, or renewable energy, uh, to make an industrial collaboration. Uh, so that because I don't have any industrial collaboration. So I want to know, uh, the, what is the real time scenario and how does really the indust?

Professor, could you provide your 3-year research roadmap in renewable engineering if you were to join our institution? How will your vision align with advancing our academic and industry objectives?

Look, in this area. So my first of all, my first of first goal is to go for a research project in this area or an incense industrial collaboration. Secondly, I also would like to have some of the projects, some of the papers, good papers to be written in this area, which would certainly require some of the experimental works as well as because so that the findings could be just verified. And thirdly, I would I I am seeking towards development. Of the developing some of the labs related to this, which you would have major renewable energy sources which in the form of panels like PV panels we can have or PV you can say like in the laboratory you can have fuel cell, which is when the search work. So I'm basically thinking for next three years, I'm basically seeing for some of the projects. Research paper and lab and if the and from those research papers.

Or the experimental works, which I can see. I could also, uh, go thinking for a patent, which could be useful for the, uh, for the researcher as well as the scientific community as well.
