The Sensing, Controls, and Probabilistic Estimation (SCOPE) Group at Purdue University is advancing research in state estimation and tracking, information-driven autonomy, and space applications. Our goal is to enable the next generation of intelligent sensors and vehicles through a combination of estimation, control, and information theory.
The SCOPE Group is always looking for talented and driven students from a diverse set of backgrounds. Interested students should email Prof. LeGrand at klegrand@purdue.edu and include a CV and short summary of why they want to join the group.
Postdocs
Andrea De Vittori is a postdoctoral researcher at Purdue University, specialising in Cislunar Space Situational Awareness (SSA), with a focus on state estimation for space object tracking, maneuver characterization and detection, conjunction assessment, and sensor fusion. He earned his PhD in Aerospace Engineering from Politecnico di Milano, graduating Summa Cum Laude with a thesis on enhanced collision avoidance strategies in the near-Earth environment. He also holds a Master’s degree in Space Engineering and a Bachelor’s degree in Mechanical Engineering, both from Politecnico di Milano, graduating Cum Laude. Andrea previously served as an Assistant Professor at Politecnico di Milano, contributing to SPACE IT UP! (SPOKE 1), where he was involved in the initial phases of developing technologies for very low-altitude Earth observation. His research portfolio includes postdoctoral work on terrestrial and cislunar SSA, a visiting researcher role at the University of Colorado Boulder addressing low-velocity encounters between space debris and operational satellites, and extensive contributions to collision avoidance manoeuvre design, low-thrust trajectory optimisation, and AI-based space object detection.
