Background: Having obtained an M.Sc. (Hons.) degree in Biological Sciences from BITS-Pilani, Pilani, India, Dr. Shruthi S. Vembar moved to the University of Pittsburgh, Pittsburgh, USA, for her PhD work. For her thesis, she studied the molecular basis of Hsp70-Hsp40 interactions in budding yeast under the guidance of Dr. Jeffrey L. Brodsky. She then moved to Institut Pasteur, Paris, France, to work with Dr. Artur Scherf for her post-doctoral studies, which was supported by prestigious fellowships such as the EMBO LTF and Marie-Curie IIF and during which, she focused on understanding gene regulation in the malaria parasite Plasmodium falciparum. Dr. Vembar joined IBAB in 2018 as a Faculty Scientist to head a research program in malaria molecular parasitology. She also received the Ramalingaswami Re-entry Fellowship from DBT for the year 2018.

Research Interest Profile:
Dr. Shruthi Vembar is interested in understanding the molecular basis of gene regulation in the malaria parasite Plasmodium falciparum. Specifically, she wants to study the role of atypical RNA-binding proteins, which are abundant in Plasmodium spp. parasites, and novel DNA modifications in parasite gene regulation and host-parasite interaction. Dr. Vembar plans to use molecular, cellular, biochemical, genetic (with state-of-the-art genome editing tools such as CRISPR/Cas9-Cas13) and omic approaches to understand these phenomena. She is also interested in the genetic diveristy of malaria parasites that are endemic to India and how host factors contribute to maintaining and/or amplifying this diversity. The ultimate goal is to identify new targets for anti-malarial drug and vaccine development.
