Dr. Lokender Tiwari, Ph.D.

I am a Senior Research Scientist, I lead a group of reseachers @ TCS Research, IIT-Delhi R&I Park, towards advancing the field of Spatial Computing. Prior to joining TCS Research, I worked at NEC Laboratories America, with Prof. Manmohan Chandraker, Dr. Quoc-Huy Tran, and Dr. Pan Ji on self-improving framework for SLAM. I received my PhD from IIIT-Delhi, with the Doctoral Dissertation Award. I was advised by Dr. Saket Anand and funded by prestegious Visvesvarya PhD fellowship. I am the recipient of Chancellor’s Gold Medal for academic excellence in B.Tech (Computer Science and Engineering) 2008-2012.
