Our lab research focus lies in plant developmental biology and metabolic engineering. Several important plants undergo activity-dormancy cycles in the Himalayan region, which is required to survive under unfavourable conditions. Also, critical developmental processes such as flowering, metabolite synthesis, tuber/corm/bulb formation etc., are regulated by photoperiod and temperature.  Thus, we aim to decipher the molecular regulation of seasonal growth, development and dormancy in economically important underground vegetative tissues.

Secondly, secondary metabolites produced in plants have therapeutic and culinary uses. These specialized metabolites are synthesized via different pathways in planta. We aim to elucidate these pathways and engineer them for enhanced metabolite production. Below are a few projects going presently in the lab.

  1. Saffron Developmental Biology
  2.  Synthetic biology approach to engineer Asafoetida's specialized terpenoid production
