Hi ! I am Shashank Kumar Roy, a researcher working at the intersection of Artificial Intelligence and Data Assimilation. I am a postdoctoral researcher at Mathematical Institute for Machine Learning and Data Science (MIDS) at the Katholische Universität Eichstätt-Ingolstadt, in Germany with Prof. Tijana Janjic. Previously, I was a postdoctoral research engineer (Ingénieur de recherche) working in Lab-STICC under Prof. Ronan Fablet at the Institut Mines-Télécom (IMT), Atlantique, Technopole-Brest, France.
Trained as a physicist, my research interests span across data assimilation and scientific machine learning applied to solve inverse problems in geosciences. My approach to such investigations involve understanding and developing state estimation algorithms, uncertainty quantification methods, graph based algorithms as in geometric deep learning. I obtained my PhD at International Center for Theoretical Sciences - Tata Institute of Fundamental Research, India. My PhD thesis titled,‘A study of dynamical instability and filter stabilit using ensemble Kalman filter’ is now available here on ICTS Thesis arxiv. In the thesis, I worked with Ensemble Kalman Filters, a class of monte-carlo based state estimation algorithm that implements approximate bayesian posterior computation sequentially over time. I completed my doctoral work under the guidance of my advisor Prof. Amit Apte & Prof. Samriddhi Sankar Ray at ICTS.
If you are someone who is interested in collaborating along some of these ideas, please feel free to reach out via email or linkedin. I am also open to collaborations and discussions on similar topics in other applied fields as well. e-mail shashankroy1997@gmail.com or linkedin Before that I completed my Bachelors in Physics from Ramjas College, North Campus, Univeristy of Delhi, India.
