Research Interests: Research in our lab focuses on plant systematics—the study of plant diversity, and explores questions of phylogeny, taxonomy and evolutionary process. While a number of different plant groups are subjects of investigation, the long-term research focus of the lab is the plant genus Eriocaulon of the family Eriocaulaceae. Our work is conducted in the laboratory, herbarium as well as in the field.

Molecular Systematics of Plants:

  • The research scope of the laboratory covers phyto-diversity documentation and discovery utilizing modern tools and techniques and exploring questions of phylogeny, taxonomy and evolutionary process. We are also interested in phylogeography, population biology and conservation biology topics. Our present focus is to work on the molecular phylogeny of Eriocaulon L. of the Northern Western Ghats in India. The genus possesses the greatest number of threatened species percentage (about 25%) in the Western Ghats. We assume the study would help in elucidation of a high-resolution molecular phylogeny of the group:
