Ali Beheshti, Ph.D., Principal Investigator

Ali Beheshti is currently an Assistant Professor and director of Tribology and Surface Mechanics Lab in the Mechanical Engineering Department, George Mason University. His research interests are inspired by the impending need for sustainable design and operation as well as prolonging the lifecycle of advanced components especially focusing on surface mechanics.  The current objective and focus of his lab is on tribology (science of lubrication, wear and friction), and contact and interfacial mechanics at different scales. The pivot of his research is centered around performance of advanced materials and components such as super alloys as well as additively manufactured parts under extreme environments.

Prior to joining Mason, he was an Assistant Professor at Texas State University-Lamar for 2.5 years and a visiting Assistant Professor at Texas A&M University. He received his Ph.D. in Mechanical Engineering with a minor in Civil and Environmental Engineering from Louisiana State University in December 2013. At George Mason and Lamar Universities he has secured near $600K in research funding from federal and state agencies (Department of Energy, National Science Foundation, and Port of Beaumont). He is the recipient of Texas State University Junior Faculty Merit Award in 2017. He has authored and coauthored near 35 peer-reviewed journal papers in highly reputable journals such as Mechanics of Materials, Materials and Design, Applied Mechanics-ASME, Tribology International and Solar Energy. He is also serving as a reviewer for several journals and served as NSF panelist, chair and co-chair for several conferences sessions such as ASME, Tribology Frontiers, and STLE as well as severed as a session organizer for K-12 STEM activities.

Manisha Tripathy, PhD Student

Manisha Tripathy is a Ph.D. student in the Mechanical Engineering department at George Mason University. She completed her Master’s in Mechanical Engineering from Lamar University in 2017.  Prior to that, she worked for 3 years as an Assistant Manager in Maruti Suzuki India Limited, the largest automobile company of India. She, also, has wide international exposure having handled projects and responsibilities at the parent company, Suzuki Motor Corporation, Japan.

Curiosity and an innate desire to explore the unknown and uncharted territories of science & engineering are the two most compelling reasons why Manisha decided to pursue a career in research. Her current research interests include multiscale modeling and simulation of rough contact between surfaces and mechanical and tribological characterizations of additively manufactured Inconel alloys. Outside of her lab habitat, she would be often found playing drums, creating interesting rock drum fills, or pondering over questions like “order in chaos, or chaos in order,” etc. Skills: MATLAB, AUTOCAD, Unigraphix, Catia, ANSYS (Workbench, APDL, FLUENT) etc.
