Gagan Kumar Sharma

Mr. Gagan Kumar Sharma is working as a Ph.D. candidate under the DST-INSPIRE Fellowship program at the Department of Physics, Indian Institute of Technology Roorkee, Uttarakhand. He is conducting research with Professor Davinder Kaur on 2D nanomaterial based composites for lead-free energy storage devices (supercapacitors). Mr. Sharma holds a bachelor’s degree (Honours) in physics from the University of Delhi. He is also a second-rank holder in his master’s in physics from Visvesvaraya National Institute of Technology, Nagpur. During his HSC/Intermediate, he emerged as a third district topper, and the Department of Science & Technology, Government of India has awarded him the INSPIRE Scholarship for UG & PG studies.

Mr. Sharma has published his research work in various peer-reviewed international journals, including Applied Physics Letters. He has presented his research findings at numerous international conferences, including AEM-2022 held at the Imperial College London. He is a recipient of the Best Poster Presentation Award for two conferences. He is also a sportsperson and loves to travel to new places.

As a Fulbright-Kalam Climate fellow, Mr. Sharma is working on the next generation lead-free and environmentally friendly energy storage technology. One of the primary goals of his research on green energy is to benefit every section of human civilization. He expects that the collaborative work will provide a tactic for commercialization at low manufacturing costs and prevent environmental imbalance. He is further optimizing several nanohybrid materials for better capacitive properties, which may solve the current energy crisis of the world. He also plans to explore various metallic foil/mesh/foam as a flexible current collector for bendable supercapacitors.

Sushmita Gouraha

Sushmita Gouraha is pursuing her Ph.D. from the Department of Hydrology at the Indian Institute of Technology Roorkee, under the guidance of Prof. D. S. Arya and Prof. Piyush Srivastava. Her research focuses on understanding the impact of urbanization on changing rainfall patterns over a complex/ mountainous terrain. She completed her BE from the Government Engineering College Raipur, Chhattisgarh, and M. Tech from the National Institute of Technology Raipur, Chhattisgarh.

Growing up in a small town, surrounded by its vibrant tribal culture and natural beauty, Sushmita felt deeply connected to her roots and harboured a desire to serve the community by understanding and addressing environmental challenges. As a Fulbright-Kalam Climate fellow at Arizona State University, Tempe, AZ, Sushmita is researching on critical concerns associated with urban dynamics, especially processes related to the impact of urban precipitation, using a numerical modelling approach. Her research will help in a better understanding of the urban processes responsible for altering precipitation patterns in complex terrains. In her free time, Sushmita enjoys exploring new places, learning about different cultures, and indulging in local games.

Harshit Sosan Lakra

Dr. Harshit Sosan Lakra, a proud Oraon tribe woman from India, serves as assistant professor in the Department of Architecture and Planning and joint faculty at the Centre for Indian Knowledge Systems at IIT Roorkee. She holds a bachelor’s degree in architecture from MANIT, Bhopal and a master’s degree in environmental planning from CEPT, Ahmedabad. Dr. Lakra was a FORD Foundation International fellow, which enabled her to pursue her second master’s in urban and regional planning from Cornell University in 2009, with a focus on international studies in planning. At Cornell University, she won the Cornell Urban Scholarship award and the Graduate Research Scholarship award. She completed her doctoral research at IIT Roorkee in 2019. In 2023, Dr, Lakra was selected as a Himalayan University Consortium fellow through which she co-leads a workgroup and collaborates with women leaders from Afghanistan, Pakistan, Bhutan, and Bangladesh.

Dr. Lakra is leading national and international projects focusing on Tribal Human Development Index (HDI), adaptation of indigenous and local knowledge systems, and Fintech Solutions for comprehensive tribal development in Chhattisgarh, along with GoAL (gender-orientated adaptive learning) for climate change and disaster risk resilience in India, Nepal, Sri Lanka, and Japan, indicating her interdisciplinary interest.

As a Fulbright-Nehru Postdoctoral Research fellow, Dr. Lakra intends to create a platform for discourse, co- and cross-learning on housing, culture, and environment at different scales and connect students, stakeholders, and indigenous communities from India and the U.S. The project will bring diverse understanding and experiences, especially for the domain and community that is less researched.

Naveen Kumar Tailor

Dr. Naveen Kumar Tailor is working as a research associate in the Department of Physics at the Indian Institute of Technology, Roorkee. He completed his M.Sc. in physics from the University of Rajasthan, Jaipur, and Ph.D. from the Indian Institute of Technology Roorkee. His Ph.D. research focused on the comprehensive description of lead-free perovskites and double perovskite single crystals, including growth and investigation of fundamental properties, structure-property relationships with cation and anion transmutation, carrier dynamics, and excited state physics using optical and electrical spectroscopy techniques, as well as applications in photodetection and X-ray detection. His Ph.D. research was recognized with the Excellence in Doctoral Research award. Additionally, he has gained experience in perovskite solar cells and explored carrier dynamics in perovskites using impedance spectroscopy, as well as fundamental photophysics in perovskite nanocrystals. Recently, he has started working on CO2 reduction, focusing on the discovery of novel materials for efficient CO2 photoreduction and studying the fundamental mechanisms behind it.

As a Fulbright-Nehru Postdoctoral Research fellow, Dr. Tailor’s has meticulously planned a project with the goal of developing cost-effective and stable X-ray detectors using solution-processed 3D/2D perovskite heterocrystals with exceptional sensitivity and low detection limits. This effort aims to increase the commercialization potential of this technology, fostering a vibrant ecosystem of X-ray detector manufacture in India and the U.S.
