Spacecraft Collision Probability Analysis: Theory and Problems Dr. Matt Hejduk 3:30 p.m. – 4:30 p.m. Thursday, September 26th, 2013 GL51, Marrs McLean Science Building The Department of Statistical Science welcomes Dr. Matt Hejduk to campus to present “Spacecraft Collision Probability Analysis: Theory and Problems.” Dr. Hejduk has spent over twenty years in the design, development, and assessment of space sensing and command and control systems. He holds degrees from Princeton University, Southern Methodist University, and the University of Dallas, and presently serves as chief scientist for the spacecraft Collision Avoidance and Risk Assessment (CARA) project at NASA Goddard Space Flight Center and as lead for the Space Surveillance Performance Analysis project at headquarters Air Force Space Command. His research interests include satellite characterization and modeling from nontime-series signature data, satellite orbit determination and characterization, and sensor and network simulation. A reception with light refreshments will be held for Dr. Hejduk at 3:00 in the lobby of the Statistical Science Department on the first floor of Marrs McLean Science.
