niloy.das@okstate.edu

Niloy is a Ph.D. student from Bangladesh who arrived at OSU in Fall 2022. He joined Cabeen Lab in early December 2022 and started his experiments in the following month. Niloy is studying the stress-sensing nanomachine ofBacillus subtilis—called stressosome—more specifically: Analyzing RsbT kinase protein’s ability to sense stress and modulate the signaling to activate the alternative σ^Bthrough molecular biology, advanced microscopic and microfluidic techniques.

jevargh@okstate.edu

I was born and raised in Kolkata, India and am the eldest daughter in my family. I graduated from Scottish Church College, affiliated under University of Calcutta in 2015 with a B.S in Microbiology. I continued my education and earned a M.S degree in Microbiology from St. Xavier’s College, affiliated under the University of Calcutta in 2017. After working for 2 years as a Junior Research Fellow at the North-Eastern Hill University, I decided to pursue my Doctoral Degree at Oklahoma State University.

Currently, I am a Ph.D student in the Microbiology and Molecular Genetics Department working with Dr.Matthew T Cabeen.
