Dr. Ullas Gurudas teaches Engineering Physics, Electromagnetic Theory and related subjects to the Engineering graduates. He is workaholic, has a passion for teaching and believes that one cannot be a good teacher without being a good researcher. He has many years of teaching and research experience in India and abroad. He was a Postdoctoral Fellow at the Institute of Atomic and Molecular Science, Academia Sinica, Taipei, Taiwan and Rutgers University, NJ, USA, Visiting Scientist to Princeton University, NJ, USA and Paul Scherrer Institute, Villigen, Switzerland and Research Scientist, New York University, NY, USA. Prior to moving to the USA, he was an Assistant Professor at the Center for Laser Spectroscopy, MAHE, Manipal, where he developed an interest in the applications of Laser Spectroscopy in Medicine. He has published many research articles in leading scientific journals. Prof. Ullas holds an Undergraduate and Postgraduate Degrees in Physics from Kerala University and a Doctoral Degree in Physics (Laser Spectroscopy) from Banaras Hindu University, Varanasi, India.

His research areas are Laser Physics, Laser Spectroscopy, Ultrafast Optics, Nonlinear Optics, and Nanophotonics.
