I am a physicist, data scientist and machine learning enthusiast currently working as a process engineer at Intel.
I conducted my graduate research as a member of Prof. Andrew Mugler’s research group at Purdue University. For my thesis dissertation I studied phenomena related to single and multicellular chemotaxis using computational tools and mathematical models. The research problems were primarily related to how noise and fluctuations in a cell’s microenvironment limit its ability to chemotax, and how collective cell behavior can improve chemotactic performance. My thesis can be found on Purdue’s library website and on my github.
