A former actor who has worked with Tamil directors like Bharathiraja, Radica started learning dance as a child under Guru KJ Sarasa, an exponent of the Vazhvoor school of Bharatnatyam. She eventually moved to the US after marriage, leaving her film career behind. After a decade long hiatus from dance, Radica reunited with it in 2000 and resumed her training under A Lakshman, a senior student of Sarasa, mostly during her visits to India during the summer vacation. Today, Radica is a well-known performer at the Chennai sabhas every winter and teaches Bharatnatyam to a class of 70 students at her institute Anjali Natya in California.
