Rowand Zara — professional headshot

I'm a double-degree student in aerospace engineering and applied mathematics at the University of Maryland, focused on the thermal and structural problems that decide whether flight hardware survives its environment — I simulate spacecraft thermal systems and hypersonic flow, then build the hardware to match.

I'm drawn to hypersonics, spacecraft thermal design, and autonomous robotics — anywhere physics, simulation, and hands-on fabrication meet. I care most about systems that have to work the first time, and I'm looking for internships and research where I can build them.
