Why I joined the ECS Ph.D. Program

The ECS Ph.D. Program is like a buffet of diverse scientific-cultures, where, you come across students, faculty and, professionals from diverse backgrounds. Moreover, the interdisciplinary group of people from around the globe allow us to share our diverse experiences and build a lifelong relationship besides academia. The friendly environment and exciting events encouraged me to continue with ECS program.

My research

My research interests include the parasites Cryptosporidium, water treatment applications, biotechnology, and proteomics

I work with Cryptosporidium parvum, a protozoan parasite that primarily causes Cryptosporidiosis in humans and other hosts. It can be fatal to immunocompromised hosts such as patients with AIDS, Cancer, Transplanted organs, etc. My research, primarily deals with understanding the environmental stimuli for causing the parasite to infect the host cells. I am also interested in investigating the post-translational changes occurring, before and after excystation.

So far, the ‘excystation mechanism’ is incompletely understood. Thus, learning about excystation can lead to a better understanding of environmental persistence and host specificity of Cryptosporidium. It can also help scientists to identify environmental and chemotherapeutic interventions.
