Research in my lab currently focuses on two aspects. The first one deals with the discovery and development of novel products from the insectivorous plant Nepenthes khasiana for the natural control of plant diseases. Our plan is to inject plant pathogens directly into the unopened pitchers of N. khasiana. If the plant triggers a response, this may lead to the identification of novel compounds that can be developed into products for the natural control of plant diseases. The second one involves the critically endangered Himalayan medicinal herb Nardostachys jatamansi. Our goal here is to understand the underlying mechanisms controlling the production of secondary metabolites in the rhizomes and roots of N. jatamansi. We can then use part of this information to genetically engineer E. coli or yeast having the ability to synthesize the metabolites of interest. Besides, we also work to understand pitcher development in N. khasiana
