Research Interests

My area of research is plant taxonomy, floristic studies, evolution and diversification of gymnosperms and conservation biology. As a passionate field botanist and plant conservationist, I believe in expanding our current understanding of species complexes, restricted distribution and evolution of ancient vascular plant groups. My interdisciplinary research aims to solve taxonomy complexity, and understand evolution and adaptability of species to varied environmental conditions over the time. Besides botanical research, I am also involved in varietal development of floricultural crops and domestication of wild ornamentals.
