Introduction
I am an incoming assistant professor of entrepreneurship and organizational behavior and theory at CMU's Tepper School of Business. My research lies at the intersection of entrepreneurship, strategy, and organizational research, focusing on how entrepreneurs create successful ventures. I am especially interested in how entrepreneurs manage change and learn from failure and success.

Research Summary
Integrating research on the persistence of founding conditions and the effects of environmental change, we explore how a venture's performance outcomes following environmental change depend on the venture's environmental conditions at founding. Using a unique sample of 1,060 new ventures from a comprehensive survey of university al...

Inspired by dynamic similarity in fluid systems, we have derived a general dimensionless form for locomotion in granular materials, which is validated in experiments and discrete element method (DEM) simulations. The form instructs how to scale size, mass, and driving parameters in order to relate dynamic behaviors of different locomotors in the sa...
Inspired by hypotheses of Resistive Force Theory, we have discovered a general dimensionless form for granular locomotion, which instructs how to scale size, mass, and driving parameters to relate dynamic behaviors of different locomotors in the same granular media. We experimentally confirm these scalings with wheel pairs of various shapes and siz...
Physical experiments were conducted using 3D printed wheels and a sand testing bed to explore the applications and predictive power of the Resistive Force Theory (RFT), an empirical model based on linear superposition designed to predict the interactive forces between solid bodies and granular media. Four-spoke wheel designs, made of four treads wi...
