Kalamandalam Radhika started dancing at the age of three, under training of Guru Rajan. In her quest to learn the different aspects of dance she learnt mridhangam vaitharis from Guru Ponniah pillai to attain mastery over the techniques of rhythm. She then learnt Kathakali from Muttar Sri. Narayana Panicker to hone her skills and talent. She later specialized in Mohiniattam having studied under the all time Great Gurus like Late Chinnammuamma and Kalamandalam Sathyabhama. She was also under the teaching of Late Kalamandalam Kalyani Kutty Amma for a short period. Her training under Kalamandalam Padmanabha Ashan in kathakali polished her Abhinayam to a great extent.

She has also given lecture demonstrations both at the National and International levels on Mohiniattam, since she has done extensive research for nine years on Mohiniattam. As a result she has systematized the basic Adavus (steps), have revived the costumes and jewellery worn by the old time Mohiniattam dancers as early as 1940. She is the pioneer to perform Mohiniattam in all languages. She has to her credit more than 2000 performances and workshops in India and abroad. Radhika has performed both at the National and International levels. She has performed for dignitaries like the SAARC delegates, WHO delegates, Soviet Representatives, Diplomats and others.
