Good day, Gowrisankar Ganesan. 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?

You've completed a Ph.D. in Hydrogeology at Anna University, and it seems you possess expertise in Hydrology, Groundwater Resources, Climate Change, and several other technical areas. Your DAAD Fellowship and high-impact research acknowledgment suggest a strong foundation in academic excellence. Given your research background, could you share your perspective on the current challenges affecting sustainable water resource management, particularly in the context of climate change?

Yeah.

Yeah. So good evening.

So I come myself. Yeah, myself, Doctor Gauri.

So, uh, now currently have in India have most, uh, 70% people in rural area depend on, uh, sustainable groundwater for drinking purpose. So, uh, not sustainability is big issue in, in India. Actually they have, uh, geogenic naturally occurring and activities affected from groundwater like arsenic, fluoride.

And, uh, nitrate.

So we want.

Yeah, we want to rectify that problem because many people not drink safe drinking water in India, according to internation reports.

We won't renew, uh, problem for safe drinking water like that. So many regions have climate, uh, variability, less rainfall.

So that groundwater?

Thank you for sharing

Yeah.

You're emphasizing the dependency on groundwater for drinking water in rural India, highlighting issues like contamination from arsenic, fluoride, and nitrate, along with challenges brought about by climate variability and reduced rainfall. It's clear you're concerned about finding sustainable solutions for safe drinking water. Could you elaborate on specific methods or techniques you believe could help address these groundwater sustainability issues?

Yeah, I think I am actually. I'm already done managing the recharge and some example case study in Southern India, actually in Bureau Indian standards in fluoride contamination for limb one, 1.5 milligram per liter. Actually we find some drinking water. Dug wells that BBQ Chittipatti village Arur region in in southern Tamil Nadu.

Take

That peoples around 1000 people they depend on open wells drinking water. So we finding research for four, four years.

Far they I have more.

Ma yeah, more fluoride concentration in groundwater. So we, uh, constructed on pilot Duckworld Reacher system and uh, to recharge for rainfall to collect in, uh, in percolate, percolate pond to constructed to recharge this, uh, groundwater system to surface water and groundwater interaction. So when rainfall, we collected that rainwater to store the tanks.

And two through and gravel levels to used tool after to pass through 111 meter difference dug well and that induced recharge ballot dug well recharge system that that collection rainfall to the bus it with Doug wells that more recharge for both season before rainfall after rainfall also that Doug gold reaches system have excellent to work that people very happy.

And during my PST also, uh, so my suggestion to reduce the for, uh, concentration of more, uh, in groundwater, we reducing first method managed recharge second method in situ for pilot duck will reach a system. This is main, uh, we focused.

Yeah. Yeah.

Yeah, yeah.

Take your time.

Yeah, sure. Uh, my research outcomes actually, uh, my PhD entitled thesis, uh, for managed acupuncture recharge to reduce the fluoride concentration. Yeah. Case study in southern India. Yeah, I think we choose the Pamba River basin. Uh, we, uh, actually they already uh, government established across the river, they constructed one check dams. So we have monitoring for every three months once and nearby check dams.

Uh, aquifers, uh, uh, how to work that reach, uh, check dams for nearby groundwater systems, some example. And that storage in upstream, that water downstream have flow, the, uh, water, but that storage water have very less concentration, uh, for, uh, because, uh, rainfall to be stored, but already that regions have more. Uh, more concentration in fluoride or arsenic, any kind of things like that.

How, uh, three square kilometer area? How to work that?

But my PhD outcome we focused on fluoride regions, so we used managed acupuncture recharge. How to work? Because my regions have two type of wells, type 1, type 2, type 1 wells have have when rainfall that time groundwater recharge but concentration also less. But another type 2 wells when rainfall recharge that time water quality very less but. Fluoride concentration very high.

Compare between type 1, type 2 wells. So, uh, we, we finding.

Why this happened during rainfall? One type of wells, uh, to occur in for saturated, like, uh, sharpened conditions. They recharge and dilute all concentration. It's good for drinking purpose. But my uh, another one type of wells type 2, they have a more recharge, but concentration very high due to.

For D sharp process occurring in my uh, regions, this is finding one. Next finding uh, one across the river, we constructed check dams. We have estimation for uh, using with groundwater modeling tool. So is working with, with check dam. How uh, water quantity and nearby surface, nearby area have more recharge be identified. And without check dam, we compare very less.

Uh, check dams have concentration fluoride as well as all water quality is good. Uh, then away from the check dams have a very high concentration groundwater quality, groundwater quality also very high. This is not fit for uh, drinking purpose. So main my PhD outcomes manager acupuncture recharge to reduce the full rate concentration.

Very less concentration, very less recharge then second findings nearby.

Second, uh, we, we have constructed the across the river, uh, 2 kilometer once, so more recharge will come.

So this is my PhD outcomes.

Yeah. Thank you.

You're welcome! Let's examine your teaching approach next. How would you engage undergraduate students in understanding complex hydrological processes using practical examples?

Yeah.

Yeah. So currently I'm working, uh, working in the Indian sub science. So, uh, getting to based on my IAC experience, I handling for UG and PG, uh, students for the CS, uh, kind of things like that. But I have easily handled because during my academic career, during my PST, I have handled for. Yeah, master level students for teaching and practical.

Under research for uh thesis, uh, I have already experienced, but I have umm, I have handling with regular practice examples. Some example I I have teaching with groundwater hydrology. Some I will compare between online to practical applications and fundamental basic concepts. Some, uh, if possible, I will be they allotted time and we take with that batch of students for field investigations.

To field to classrooms and so easily they will, uh, understand.

Yeah. Yeah, if possible I will compare compare for online class teaching and real life examples also.

That's an excellent strategy. It connects theoretical knowledge with real-world applications and encourages deeper student engagement. Would you say your approach emphasizes problem-solving and interactive learning during field studies, or do you focus more on observing environmental systems?

Yeah.

Uh, I'm focused on, uh, more environmental systems because environmental system and field investigation also, uh, because uh, uh, is environmental, uh, environmental also OK, because we teaching something small, small scale, they not understand. So we will take that field and the laboratory also some example we'll take.

Uh, some they did not understand. Suppose we will approach with laboratory, with instruments how to work this some example, some any methods, uh, like example uh, address geological problem pumping test Uh. So we, we, we mentioned uh, for RCD, we calculated like TS equal to KB. This is a transmissivity like that they did not understand. So we have set up 1 laboratory we will give.

Practical class.

Uh, take some, uh, some practical application. It's useful for you, just you just students for easily understand.

Some, then we will.

You've emphasized combining fieldwork, laboratory setups, and practical applications to bridge gaps in understanding challenging environmental and geological concepts. It demonstrates a thoughtful approach to teaching. How do you evaluate the effectiveness of your teaching methods and the students' grasp of the subject material?

Yeah. And, uh, I have evaluated, uh, based on, I will give one, uh, one, uh, one example. So how do they sort out?

Uh, like example, I will give one, uh, some sand columns. So you will take some drinking water or tap water. Suppose you'll suppose some example I will take very important for, uh, estimation of groundwater hydrology, like groundwater flow estimation, aquifer parameter estimation, sea-based analysis, groundwater recharge estimation like that. So suppose I will take that class. So, uh. Yeah, Q is equal to KIAQS equal to recharge, K is equal to idyllic conductivity is equal to hydraulic gradient is equal to area of cross section. So suppose I take.

Online or offline classes suppose they did not understand some example I will take one I will call one students I give to one liter water one we have one we have one set up like any small maybe we'll take one plastic open cans. So you will put that water so that water how to enter how?

How long they take this is called Tarsila.

So I will I I will teach easily to the students.

With the practical application.

You've demonstrated a clear and effective approach by using hands-on experiments, such as flowing water through sand columns, to illustrate hydrological concepts like recharge and permeability. By integrating theoretical equations with tangible examples, you're ensuring students gain both conceptual clarity and practical understanding. Do you have strategies to ensure students connect these lessons to broader environmental issues or real-world water management challenges?

Yeah, sure. Because nowadays where we very real world, we are known for issues there in like groundwater systems, surface water like that. Suppose some example now trending with microplastic in groundwater system in in the world across the world, including in India, Tamil Nadu as well as but.

Uh, that student not aware that's a groundwater challenges and groundwater problem. So some example regularly you will drinking what type of water. Just I ask this small question, they tell something. I drinking for RO water. I drinking for canned water. I drinking for surface water, I drinking for, uh, tap water, kind of things like that. So first you, uh, understanding basics concept of our drinking water daily usage.

Some example we drinking so total disaster solids what total dissolved solids you will think that much first because your Bureau and standard they recommend limited 500 milligram per liter below and you go also have health concern. So bust we want our then you based on based on you understand then you will establish worldwide what problem is there for like anything microplastic.

Nitrate, nitrate, fluoride and arsenic kind of things so have many health concern. So first that students wants uh involved daily usage of drinking water.

And domestic use also, so both water have what problem. So first we have understand then we identified environmental challenges.

You've successfully explained how engaging students with their daily experiences, such as analyzing their drinking water, helps them appreciate broader environmental challenges. By grounding theoretical knowledge in real-world relevance, you're inspiring them to connect learning to global water quality issues like microplastic contamination or nitrate pollutants. Would you like to highlight any particular initiatives or collaborative research ideas you’d propose to advance student involvement in addressing these hydrological challenges?

Yeah. Uh, so, uh, I think during my PhD now, currently I'm working with the AC already I mentioned in my CV. So already I collaborate with uh, uh, for free University Berlin I published in access scientific data paper and uh, currently Vit university also Vit and I, he delved Netherland. We already collaborated and started to working with the microplastic.

And groundwater systems, we already submitted one paper. So I think now currently working with IAC 2 for Columbia State University in New York for ISO isotope geochemistry. So already we have I have already published many countries along with international reputed journals. If I get chance so I will. I have experience in groundwater ideology, hydrogeology, hydrogemia and groundwater. So based on expertise, so I will find a world.

Uh, what problem in, first of all, uh, we'll find then based on I will write my expertise for proposal. Then I have, I know where a lot of peoples in colleagues in different across the world. So I will collaborate and, uh, to establish, uh, research proposal and submit for some Funding Agency like dad and dad federal government fellowship or, uh, USDA. Uh, like national fellowship of the US?

Wait, what problem is available like example geogenic or androgogenic and then our nature or our climate change? So whatever it is they have.

So kind of things like that, I will, uh, I will apply and bring with, uh, new projects, uh, based on my expertise.

You've outlined an impressive record of international collaboration and publishing across globally recognized journals. Your ability to engage with institutions like Free University Berlin, Columbia State University, and others demonstrates a strong capacity to build impactful research networks. By targeting specific hydrological challenges—be it geogenic or anthropogenic causes, climate change impacts, or emerging issues like microplastics—your approach reflects academic rigor combined with practical application. This focus on fostering research collaboration and securing funding aligns well with advancing both institutional and student involvement in water resource studies. Let's now discuss how you envision contributing to curriculum development or the broader academic community as a Water Resources/Hydrology Professor. What's your perspective on this?

So. As as I'm basically so I have.

I have several years experience the in groundwater ideologies field. Suppose I get chance in working with the VAT, so I will develop individual research group to to developing for developing for groundwater challenge.

Challenges in Group. So I will suggest some uh, some ideas in in country and uh, publish the reputed journals and the inventory students.

You clearly aim to establish a focused research group addressing groundwater challenges, with the intent to publish widely and mentor students. Could you elaborate on the kinds of resources or support you'd consider essential for building this academic and research environment effectively?

Some rural community. This is my aim.

Your focus on improving groundwater quality for rural communities by forming a dedicated research group demonstrates your commitment to societal impact. This aligns well with the academic mission of advancing both research and real-world application. Given your intent, what unique teaching methods or interdisciplinary collaborations do you plan to incorporate to ensure students and researchers are thoroughly engaged with these community-oriented goals?

So based on my experience, I will take course subject, groundwater engineering, environmental impact assessment, enormous sciences, underground groundwater hydrology.

You aim to offer a curriculum that combines technical depth in groundwater engineering, environmental impact assessment, and hydrogeology with real-world applications. By focusing on these areas, you're equipping students to address complex water resource challenges effectively. Would you also explore integrating data science or advanced modeling techniques into the curriculum for addressing hydrological issues?

Uh, during my academic career nowadays, uh, now also I'm working within IAC, I have already, umm, I have already used my, in my research groundwork model, uh, for using with the feedflow, uh, for estimation of groundwater flow, uh, then estimation of groundwater recharge kind of things. Uh, so using within 3 dimensional finite element modeling, using with climate data to assess the effect of recharge from check dams and how. To work with groundwater quality, then what direction in groundwater flow already I done during my academic career. So I already published one uh, machine learning to using with uh, uh, accessing of groundwater quality in Cuddalore region. This paper also we published in collaborative with VIT university already. So I have some have experience is there in machine learning as well as groundwater modeling. So groundwater modeling I done 1 chapter in during my.

You see using with the free flow software.

Your expertise in advanced modeling techniques, such as three-dimensional finite element modeling and machine learning applications for groundwater quality analysis, demonstrates a strong foundation in integrating technology with environmental studies. By incorporating these into your curriculum, you'll equip students with cutting-edge tools for tackling hydrological challenges effectively. Let's transition to the next part of the discussion. Could you delve into how you plan to balance your teaching responsibilities with advancing research initiatives?

Yeah, I'm balancing because I have experience with the Indian Institute of Science. So, uh, already I have uh, I have aligned with, uh, experience with mentoring students and published for individually published in research articles. So based on this IAC experience, I will handled for uh, uh, UG and PG students and uh, I will publish for individually. Donors, so kind of things like that.

Balancing teaching and research through mentoring undergraduate and postgraduate students, coupled with a robust record of publishing, reflects your ability to integrate both facets effectively. This is essential in maintaining academic excellence. Lastly, considering your extensive background, how do you envision contributing to the broader institutional goals, such as advancing research collaborations, community impact, or interdisciplinary programs?
