Poulami Nandi

Dr. Poulami Nandi is a postdoctoral fellow at the Indian Institute of Technology Gandhinagar, Gujarat since March 2022. She received her Ph.D. in physics from the Indian Institute of Technology Kanpur (IITK) in April 2022. She earned her master’s in physics from IITK and joined the research group of Prof. Arjun Bagchi in 2017 to pursue her Ph.D. Her doctoral thesis “Carrollian Conformal Symmetry and Holography” focuses on Carrollian conformal and BMS field theories, and their relations with the holographic principle for asymptotically flat spacetimes.

During her Ph.D., Dr. Nandi was awarded two international fellowships: the Fulbright-Nehru Doctoral Fellowship 2019-2020 for nine months to visit the University of California, Davis and the Overseas Visiting Doctoral Fellowship 2018-2019 for 12 months by the Science and Engineering Research Board (SERB), Government of India. She was also affiliated with the Vienna University of Technology (TU Wien), Austria for six months from August 2019 before moving to California in 2020. She was awarded International Travel Support (ITS) by SERB in 2022 to present her work at the prestigious annual conference “Strings” in Vienna. She also received the INSPIRE scholarship from the Department of Science and Technology, Government of India during her undergraduate studies. She has co-authored several publications in international high-impact journals and presented her works through multiple seminars and posters in India and Europe.

The holographic principle is one of our best hopes to understand quantum gravity. One of its most prominent examples is the AdS/CFT correspondence, which is also deeply connected to diverse branches of physics, such as condensed matter, quantum information, and optics. During her Fulbright-Nehru Postdoctoral Research fellowship, Dr. Nandi is investigating the interface of quantum theory of gravity and theory of quantum computation. She is working to understand aspects of quantum information theory for non-Lorentzian field theories, in the context of flat-space holography, and also the dynamics of quantum systems.

Rishiraj Adhikary

Mr. Rishiraj Adhikary is a Ph.D. student at the Computer Science Department, Indian Institute of Technology (IIT) Gandhinagar, Gujarat. His research interest is in human-computer interaction, ubiquitous computing and sensor-enabled embedded systems that can impact healthcare delivery or pave the way towards making healthcare more accessible. His current research focuses on retrofitting consumer-grade masks with sensors to detect lung health. His prior work has also studied the perception of people around air pollution to aid in risk communication.

During his Fulbright-Nehru Fellowship, he will study how contexts like human activity can be leveraged to implement opportunistic sensing techniques in smart masks. Successful research on context sensing will pave the way to preserve privacy and reduce the energy consumption of a smart face mask.

Mr. Adhikary received his B.Tech. (Electronics and Communication Engineering) from Gauhati University, Assam, where his capstone project was recognised as the best project. He has successfully conducted events targeting school children in the past where he has demonstrated prototyping tools to help students understand the basics of electronics. He also takes a keen interest in teaching undergraduate and school students.

Sonam Sonam

Dr. Sonam obtained her doctorate in earth sciences from the Indian Institute of Technology, Gandhinagar in 2019, and her B.Sc.(H) and M.Sc. in geology from Hansraj College, the University of Delhi in 2011 and 2013 respectively. Her specializations are in the field of fluvial geomorphology, hydrology, and geospatial science.

Dr. Sonam was awarded the CSIR-Research Associate grant in the year 2021 and is currently a CSIR-Research Associate at IIT, Gandhinagar. She is also recipient of the CSIR-UGC JRF fellowship in the field of earth, atmospheric, ocean and planetary Sciences 2013-2018, and the DST-SERB International Travel grant to present her work at the European Geosciences Union (EGU), 2018. After her Ph.D., she worked as a post-doctoral Research Associate on the arid zone rivers and biodiversity, as a part of the Gujarat state climate change project under the National Mission for Strategic Knowledge on Climate Change, DST, Government of India.

Dr. Sonam’s Fulbright-Kalam Climate fellowship for Postdoctoral Research project is regarding environmental flow modelling for sustainable management of river systems. To understand the gravity of the crisis associated with degraded river health and to ensure sustainable development for all stakeholders, a combined socio-hydro-geomorphic approach, including indigenous knowledge and geospatial techniques, is needed. However, this integrated strategy lacks well-defined methodology. Dr. Sonam is using geospatial tools and integrating them with indigenous knowledge to model environmental flow needed to ensure a healthy functioning river: geospatial techniques are used to analyze river morphological susceptibility to exogenous forcing and indigenous knowledge is used to explain a river’s flow requirements at local scales.

Vinod Narayanan

Dr. Vinod Narayanan earned his Ph.D. from Jawaharlal Nehru Centre for Advanced Scientific Research, Bengaluru, and is currently Associate Professor at the Indian Institute of Technology Gandhinagar, Gujarat. He joined IIT Gandhinagar in 2009, where he supervised two Ph.D. students and twenty master’s students.

Dr. Narayanan’s research expertise is in theoretical and computational fluid dynamics. His research interests are hydrodynamic stability and transition to turbulence, fully developed turbulence, mixing and combustion in high-speed flows. His team has developed various computational models in hydrodynamic stability and flow control. He has authored more than 20 publications in peer-reviewed international journals and more than 50 articles in conference proceedings.

During his Fulbright-Nehru Academic and Professional Excellence fellowship, Dr. Narayanan aims to develop numerical models and experimental techniques for suspensions in isotropic and wall-bounded turbulent flows. This project fundamentally investigates the fluid mechanics of suspension, its basic properties, and its effects on large-scale dynamics, using a combination of high-resolution numerical simulations and state-of-the-art laboratory experiments.
