University Post-Doctoral Fellow

Email: unni.ukps87@gmail.com


Dr. Unnikrishnan is a University Post-Doctoral Fellow (UPDF) in Prof. G.S. Sailaja’s team at the Department of Polymer Science and Rubber Technology since August 2021. Before joining in this group he completed his post doctoral project in large animal model for the clinical translation of bone grafts for tissue regeneration at Amrita Centre for Nanosciences and Molecular Medicine. He obtained his Ph.D. degree in Biotechnology from Vellore Institute of Technology, 2017 under the supervision of Dr. M. A. Jayasri, where his research focused on bio-prospecting of seaweeds with special reference to diabetic complications. He presently works on the project “Biocompatible 3D Scaffolding through Femtosecond Laser Photo- polymerization for Tissue Engineering and Regenerative Medicine”.
