BRIEF BIO
Dr. Sheenu Thomas took her M.Sc. (Physics-1991) and Ph.D. (Experimental Solid State Physics-1999) from Cochin University of Science and Technology. She joined CUSAT as a faculty member in 2001. Currently she is Professor at International School of Photonics, Cochin University of Science and Technology on internal deputation from Cochin University College of Engineering, Kuttanad. Her research area of interest are studies on photo-induced, thermal and optical effects of chalcogenide glass based photonic materials. She has 29 years of research experience and over seventy international journal publications to her credit. She has successfully guided ten doctoral students. Four researchers and two post-doctoral fellows are currently working under her supervision. She is the principal Investigator to funded research projects and life member of IAPT, PSI.

RESEARCH INTERESTS
nanomaterials, optical and thermal studies on chalcogenide glasses, photoinduced effects of amorphous solids, photonic materials
