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.
