I just completed my PhD in the Kline lab, in the microbial pathogenesis of group A streptococcus in infectious diseases, and am currently working in SCELSE as a Research Fellow. I have a Master’s degree from University of Hyderabad and a Bachelor’s degree from Osmania University, India, both specializing in biochemistry. I have an extensive research experience with specialization in muscle biology as well as bacterial biofilms in infectious diseases. When I am not in the lab, I enjoy reading, with special interest in post-colonial literature and classics. I am also an avid art enthusiast and blogger and love to travel and cook for friends.

During my PhD, I developed in vitro and in vivo models to characterize biofilm formation by a necrotizing strain of group A Streptococcus (GAS), in collaboration with Dr Emanuel Hanski, my co-supervisor from Hebrew University, Jerusalem. GAS causes a wide range of skin and throat infections, but is also involved in fulminant and systemic infections like toxic shock syndrome and necrotizing fasciitis (NF), also known as the “flesh eating disease”. My studies delineated molecular determinants of biofilm formation during NF by a necrotizing strain of GAS in the host, and I demonstrated a novel role of GAS secreted streptolysins in this event thereby establishing a link between bacterial pathogenesis and biofilm formation.
