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 2003.
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 Computation and Information.
She also organizes audit courses in Classical music, Indian and Western, at the Institute,
