Assistant Professor at University of Pennsylvania (Mechanical Engineering and Applied Mechanics)

Philadelphia, Pennsylvania, United States

About

I graduated from Princeton University with a bachelor's in Mechanical and Aerospace Engineering in 2017, spent a year at the Technical University of Darmstadt in Germany as a Fulbright fellow, and then obtained a master's in Mechanical Engineering from Stanford University in 2020 before moving with my advisor, Prof. John Dabiri, to the California Institute of Technology. I completed my Ph.D. in Aeronautics in 2023 on the unsteady aerodynamics of wind-energy systems, and was a Distinguished Postdoctoral Fellow in the Andlinger Center for Energy and the Environment at Princeton University for one year. I joined the Department of Mechanical Engineering and Applied Mechanics as an assistant professor at the University of Pennsylvania in August 2024. I seek to push the frontiers of experimental fluid-mechanics research at lab and field scales to answer pressing questions regarding how humans can live more harmoniously with the air we breathe. My interests span the intersection of unsteady aerodynamics, climate science, and wind-energy technologies, as well as their ecological, environmental, and societal implications. I also love capturing the imaginations of students from grade school to grad school with the fascinating nature of the world we share, and empowering them to serve those in need through empathetic engineering design.
