Radhika did her PhD work on formal quantization techniques at the Institute of Mathematical Sciences, Chennai, under Dr G Date. Her Thesis was entitled “Studies in Quantization: Methods for Constrained Systems and Semi-classical Spectra of Many-body Systems”. She was a CSIR Research Associate at Harish Chandra Research Institute, Allahabad till 2001 December after which she joined the Physics Group at BITS Pilani (Pilani Campus) where she was associated with the DLPD. She moved to the Goa Campus in December 2004.
Her research interests include Mathematical Physics (formal quantization), Many-body Physics (multi-particle clusters, anyon physics, fractional statistics), High Energy Physics (gravitation, string theory) and more recently, Quantum Information and foundations of quantum mechanics.
She is passionate about teaching and tries out different methods of active learning and blended learning in her classes.
She has recently written a text book on Quantum Physics and Quantum Information addressed to undergraduate students, published by CRC Press in 2015
She also has an abiding interest in Indian Classical music, being an amateur vocalist and veena player.
She has started research into the acoustic characteristics and construction mechanics of Indian musical instruments, in collaboration with the Mech Engg dept.
