Short CV
Venugopal received his Bachelor’s Degree in Physics from Fergusson College (Autonomous) affiliated to Savitribai Phule Pune University, Pune, India in 2019. He completed his 3 years master’s degree, M.Sc. (Tech) in Engineering physics with Photonics specialization at the National Institute of Technology, Warangal, India in 2022. He completed his master’s thesis on “Speckle-based deep learning assisted free-space optical communication”. In September 2022, Venugopal started his Ph.D. at the Nanophotonics and Metamaterial group, Optoelectronics Research Center (ORC), University of Southampton.
