Ramesh Chandra Sau

Introduction

Dr. Ramesh Chandra Sau is an Assistant Professor and INSPIRE Faculty Fellow in the Department of Mathematics and Computing at IIIT Raichur.
He received his Integrated Ph.D. (M.S. + Ph.D.) in Mathematics from the Indian Institute of Science (IISc) Bangalore, under the supervision of Prof. Thirupathi Gudi.
Prior to joining IIIT Raichur, he held postdoctoral positions at IIT Bombay, The Chinese University of Hong Kong, and TIFR-CAM Bangalore.
His research lies at the intersection of numerical analysis, finite element methods, optimal control problems, and emerging deep learning techniques for PDE and optimal control problems.
