About Me

I am a PhD candidate in the Department of Mechanical, Materials, and Industrial Engineering at the University of Cincinnati, working at the UC Lab for Interfacial Dynamics under Dr. Kishan Bellur.

My research develops computational models of liquid-vapor phase change and transport phenomena. Recent work combines kinetic and transition state theory to build CFD-embedded multiscale models of evaporation in cryogenic fuels, eliminating common unphysical tuning parameters. Currently, my work investigates how phase change influences the stability and dynamics of thin films and moving contact lines using finite element analysis and molecular dynamics simulations.

During my graduate career, I have worked as a Research Assistant at the P&G Digital Accelerator and taught three undergraduate courses as instructor of record at the College of Engineering and Applied Science. I previously earned a Master of Science in Aerospace Engineering and a Bachelor of Science in Mechanical Engineering Technology from the University of Cincinnati, including five semesters of co-op experience in design and manufacturing engineering.
