Sangeeta Murugkar

Dr. Sangeeta Murugkar is a Full Professor in the Medical Physics Group in the Department of Physics at Carleton University in Ottawa, Canada. She is an expert in developing non-invasive, rapid and cost-effective optical imaging instrumentation and quantitative analysis techniques utilizing lasers. 

Sangeeta established the Laboratory for Laser-Assisted Medical Physics and Engineering (LLAMPE) in the Department of Physics after joining Carleton University in 2013. Following her undergraduate degree in India, Sangeeta completed her PhD in Physics at the University of Michigan, Ann Arbor, studying the fundamental physics of semiconductor superlattices using Raman spectroscopy. She developed her interest for real-world applications of photonics as a post-doctoral fellow at McMaster University for two years and a Research Scientist in the telecommunications industry giant JDS Uniphase in Ottawa for five years. Sangeeta discovered her passion for Biophotonics in 2006 while working as a Research Associate to Prof. Hanan Anis at the University of Ottawa for five years. She enjoyed the opportunity to work with Prof. Robert Boyd, an international expert in nonlinear optics at the University of Ottawa from 2011-2013.
