Master's Students

Rutvik Dagadkhair

Rutvik Dagadkhair is a master's student at Virginia Tech, working with Dr. Mathieu Joerger.

Casey Smith

After obtaining his BS in Mechanical Engineering from Rowan University (New Jersey), Casey Smith worked for Canon Virginia Inc., where he designed and programmed robotic assembly systems. Experience with 6-axis and self-driving robots led him to Virginia Tech to pursue research with autonomous systems.

Casey Smith's work is focused on analyzing and reducing the collateral damage created by precise counter-UAV systems for deployment in potentially cluttered airspaces. A working knowledge of UAV PNT architecture, GNSS, and RF devices is required. His work consists of derivations from first principles followed by MATLAB simulations.
