Dr. Rahul Panchal

About

I am a Postdoctoral Researcher at NYCU Taiwan. I have completed my Ph.D. in liquid crystal optical device at Indian Institute of Technology, Delhi, New Delhi, in 2025. I got Masters in Physics from Sant Longowal Institute of Engineering and Technology, Punjab, in 2018 and B.Sc. (H) in Physics from the University of Delhi in 2016. The current area of research relates to liquid crystal-based electro-optic devices and fiber optic sensors.
