Divya Venkatasubramaniam Iyer

Kanika is born as Divya Venkata Subramaniam in a Tamil-speaking Iyer Brahmin family in Madurai. Her father Venkata Subramaniam Iyer was an engineer. She won the Tamil Nadu State Award for Educational Excellence in 1999. She pursued her Mechanical engineering degree from 1999 to 2003 in BITS Pilani.

Having improved her singing talent since childhood by participating in pop music and light music shows, Divya was interested in performing arts. While she was still studying, she gave stage performances as a pop singer from time to time. When she was scheduled to perform at the Miss Chennai beauty pageant in 2001, she was selected to participate in the pageant after a model had backed out at the last minute. Despite lack of experience, she emerged victorious in the contest, which later paved way for a film career. Susi Ganesan spotted Kanika on a magazine cover page and insisted on her performing the lead female role in his second feature film. Divya eventually entered the Film industry, accepting the offer, while her name was changed to Kanika. Her debut film was the Mani Ratnam-produced Five Star (2002) with Prasanna, who made his acting debut as well, in which Kaniha portrayed a traditional village girl. She completed the entire film during her summer holidays, since she was a student.

Kanika turned down all projects that were subsequently offered to her, including films by S. Shankar and P. C. Sreeram, and went on to complete her graduation. Even before she finished her graduation, she completed her Telugu debut film Ottesi Cheputunna during her winter vacations, acting under another stage name Sravanthi. In regard to her performance, Idlebrain wrote: "Sravanthy looks homely in the film and suited the character. She performed well. She is good at dances as well".

After completing her studies, Kanika decided to give herself a go at the Tinsel towns. She starred in the Kannada film Annavaru (2004), a remake of Mani Ratnam's Thalapathi (1991), stepping into Kannada filmdom, too. She followed the movie with a cameo role in Cheran's Autograph. Kaniha next appeared in a comedy oriented role in a commercial film by K. S. Ravikumar, Aethiree along with Madhavan, Sada, in which she portrayed a "naughty Brahmin girl". Sify labelled her performance in the film as "outstanding". She went on to play the female lead in Dancer opposite physically disabled Kutty, following which she returned to Telugu cinema, accepting to reprise her role in the Telugu remake of Autograph, Naa Autograph, playing the same role as in the original version. She proved to be an actress to reckon with in the Kannada film Sye, a remake of Tamil film Dhill. She finally ventured into Malayalam cinema as the heroine for the campus-based film Ennitum.

Later in 2006, she appeared in her biggest project until then, Varalaru, directed again by K. S. Ravikumar, in which she shared screen space with Ajith Kumar. She won plaudits for her role as a mentally disordered girl. After a two-years gap, her most recent Kannada film Rajakumari opposite Ravichandran got released, in which she again got to play the female lead role.

After her marriage, when she was supposed to bid adieu to the film industry, Kanika returned to Malayalam cinema in 2009, with the films Bhagyadevatha, directed by veteran Sathyan Anthikkad and starring Jayaram and Narain as well, and Pazhassi Raja, directed by reputed director Hariharan and starring Mammootty, Sarath Kumar and Padmapriya among others. While the former one, in which she played the role of a homely Christian girl, was highly successful at the box office, the latter one, a biographical historical film, in which she played the role of a queen opposite Mammootty. Her performance in Bhagyadevatha led to her winning several awards. Her rising adulation in the Malayalam industry saw her eventually sign laudable roles in the films My Big Father and Christian Brothers before she took a maternity break.
