Yogita Kalra

Dr. Yogita Kalra is an Associate Professor in the Department of Applied Physics, Delhi Technological University (DTU), Delhi .

I had developed a keen interest in the sciences in my school days. I took up Physics as my main subject during graduation and went on to complete M.Sc. in Physics from the Indian Institute of Technology (IIT), Delhi, India in 2001. In 2007, I received my Ph.D. degree from the University of Delhi, India. My journey of teaching started in Gargi College in 2006-07 and my will to pursue a career in it was strengthened over time as I joined and continued at Bharti Vidyapeeth College of Engineering, Guru Gobind Singh Indraprastha University from August 2008 to January 2010.In the same year i.e in 2010 my full time commitment to a life of teaching, learning and research was confirmed with a regular job as an Assistant Professor at Delhi Technological University.  My research interests mainly include design of all optical integrated devices, optical nanoantennas and nanophotonic devices based on photonic crystals and meta-materials.

I have been working as the coordinator of the Technology Information, Forecasting and Assessment Council (TIFAC) – Centre of Relevance and Excellence (CORE) in Fiber Optics and Optical Communication, DTU under Mission Reach program of Technology Vision 2020.

One of the main motivation factors behind my professional work has been to find ways to utilise the wonders of Physics to develop new technologies and contribute to the overall development of society and nation. Our dream of becoming a developed nation can be fulfilled by making the advances of Technology available and accessible to all and I hope to contribute to the same in my own small but significant manner.
