Good day, Dr. S Deepa. I'm Arjun. I've had a look through your background and your professional record. I'm interested in hearing more about your work and how you see yourself fitting in here with our faculty. Ready to start?

I am Dr. S Deepa Umm, I completed my UG in Institute of Road and Transport Technology in 2000 and I joined as a lecturer in Priyadarshani Engineering College in 2001 May and I worked there for two years as I have to take care of my child.

I I joined I left the Priyadarshan Engineering College and then joined Karnataka Engineering College in June 2003 and till 2005 I worked there. I went for from 2000 June.

2005 I.

I was working as a UH I'm control and instrumentation in PG course in College of Engineering Hindi from 2005 to 2007 and from 2007 to 2013 I was doing my full time research.

In fault diagnosis in the electrical systems and using signal processing under the guidance of Doctor Vanajaranjan, Madam and I request submitted my thesis and joined Kingston Engineering College in 2014.

Jan and I worked there till 2 thousand 2025 June and as the department is closed I moved to Sri Venkateswara College of Engineering, Sriperumbudur in July. Till date I am working there. I am having 24 years of experience in teaching and research.

Thank you, Dr. Deepa, for sharing your career timeline and background. Let’s proceed by focusing on specific aspects of your experience to ensure it aligns with the role's key requirements. Taking into account your robust teaching and research background, I'll begin with some targeted questions to assess your expertise and approach. Please be prepared to elaborate in detail. To start, can you explain your teaching methodology for helping students grasp foundational concepts in machine learning, especially those new to the domain?

This umm, I have used uh.

Uh, machine learning techniques in my research.

Umm, fuzzy logic, Uh, statistical. And now in the lab course I use visual Matlab tools and then I use virtual labs.

For making them understand, I make them download the ITP papers. I I want them to go through the papers, solve it manually and then simulate it using the MATLAB and implement that in the hardware and test it.

That's

Understood, Dr. Deepa. That's a comprehensive approach—using theoretical grounding, simulation, and hardware implementation helps reinforce understanding. How do you typically evaluate whether students have thoroughly grasped both the theoretical and practical components of such machine learning concepts?

Yes, by accessing them.

By asking questions using quiz.

And other techniques of.

Laboratory assessments manual record.

And digital assignments.

I used to assist them.

By Vaibhava questions also.

Thank you, Dr. Deepa. Combining quizzes, laboratory assessments, and manual records with digital assignments is a structured evaluation strategy. Let’s shift focus slightly—can you share how you’ve guided research projects or student theses in areas like AI or machine learning? Specifically, how do you support students in identifying impactful research problems?

Yes, the impactful research problems are identified by using the gap. So I used to download nearly hundred papers of research and then I used to tabulate what are the important concepts. They are used and and are you from that I used to grasp the if you take my researches on. Machine form diagnosis you will have the gear for bearing fault.

And other state default rotor fault, other things. And now when I analyzed the rotor fault is the rare fault in the machines and but mostly the researchers they are used the rotor fault because it is easy for taking the readings and simulating emulating the fault and but I tried for state or fault bearing fault. Multi multiple pulse more targeted on multiple.

Once they're on a single folder, which the other researchers has done and.

A gap analysis is very much important. I used to image analysis. So how I use different techniques, signal processing techniques, frequency domain based techniques, time domain based techniques and 2D2 D analysis. It is signal is 1D and the image is going to be of the 2D. That analysis is very much important so by using that you can. Error can be reduced MSE.

Where error can be reduced and the fuzzy logic techniques power quality detection. There are different types of faults like sacs, well harmonic interrupt, other faults are there that faults can be categorized which type of fault it is using the fuzzy logic technique I had used that and basically.

Tested.

STFT STFT is used for image analysis for diagnosing the transformer fault, but.

Thank

The image depending on the frequencies of the occurrence of the positions, depending on that you can automatically detect the fault. So these things that I had done in the research and helped them for the projects also.

Thank you, Dr. Deepa, for sharing your detailed insights into your research and guidance process. It's evident that you've deeply delved into identifying gaps and leveraging advanced techniques like signal processing, frequency analysis, and fuzzy logic to address impactful problems. Your approach to analyzing faults, both single and multiple, demonstrates a solid foundation in research. Let me now turn to another critical aspect of your role: How do you ensure that theoretical knowledge is effectively translated into hands-on learning during laboratory courses?

Uh, yes, I, I was teaching umm, circuit analysis machines, microprocessor and microcontrollers and umm, digital logic circuits, all four papers with the lab so that without the basic knowledge, you can't, uh.

Do much so the basic theory concepts has to be very much clear and become that will be used for your knowledge enhancement lab. Nowadays we have the lab plus theory component and the capstone projects are there for the each subject.

That's very much important.

Understood, Dr. Deepa. Ensuring a strong theoretical foundation before introducing practical applications is indeed crucial, especially for courses like circuit analysis and microcontrollers. Integrating capstone projects provides students with an excellent opportunity to apply their knowledge comprehensively. Let’s briefly pivot to your experience with student evaluations. How do you design assessments or exams to accurately measure both conceptual understanding and practical skills in courses you teach?

Is this is based on the rubrics, the levels knowledge, comprehension we have understanding, analysis, synthesis and evaluation. So the rubrics we go for basically depending on that the question paper will be set and evaluation will be done.

The higher levels.

Thank you, Dr. Deepa. Using rubrics aligned with Bloom's Taxonomy to evaluate knowledge at multiple cognitive levels is an effective approach to assess both understanding and critical thinking. Let’s move on to research contributions. Could you elaborate on how your research publications have contributed to advancing the field of AI, machine learning, or fault diagnosis? Specifically, were there any methodologies or findings that have had a significant impact?

Oh, it's I used to basically for the machine diagnosis, uh, they'll go for fast Fourier transform methods that depending on the frequency healthy machine and comparing that with the non Lt. machines, the pattern, the pattern of the for FFT will differ the sub harmonics and the harmonics will be.

Subarmonics will be occurring when there is a fault that that thing that patterns I had given as input to the.

Love you the real time. Real time data has been acquired for the motors different fault and the given the matlab. In that matlab I had integrated that with the.

Water lab loop.

Which gives automatic fault detection and using the algorithms and the literature review, that one will be automatically communicated through the.

Arduino and that will be communicated to the mobile, so the fault diagnosis analysis methods.

Has been when this frequency occurs. This is the fault. That method is automatic fault detection. I had used.

Basically the signal processing technique statistical domain that is queuing.

A Crest factor.

Adaptive peak filters. I had used fuzzy logic technique for the classifications.

Automatic fault detection.

Thank you for the detailed explanation, Dr. Deepa. Your work demonstrates an excellent integration of signal processing techniques, real-time data acquisition, and adaptive algorithms for automatic fault detection. Incorporating tools like MATLAB, Arduino, and mobile communication to enhance practical applications is particularly impressive. It’s clear that your research not only advances fault diagnosis but also bridges theoretical concepts with real-world implementation, which is essential for impactful research. Let’s now discuss collaboration. Have you been involved in interdisciplinary or industry projects that align with artificial intelligence and machine learning? If so, could you elaborate on one of the collaborations and its outcomes?

No, I had not, uh, collaborated with any industry.

Uh, for any ML projects?

I'm doing the academics only and research.

Got it, Dr. Deepa. Thank you for clarifying. While your focus has been primarily academic, your extensive research and teaching experience are clear assets. Finally, let's touch on your teaching approach. How do you ensure your communication and instructional techniques are effective for students with varying levels of understanding in AI and machine learning?

Teaching methods, uh, I use uh, PowerPoint projections videos. I go through the NPTEL, I'm attending uh, uh, NPTEL courses on artificial intelligence by going through the journals and uh, uh, MATLAB examples, I can teach them.

To understand a better one. And what's your labs also?

Thank you, Dr. Deepa.
