Professor Robert Ghrist

Robert Ghrist is the Andrea Mitchell Professor of Mathematics & Electrical/Systems Engineering at the University of Pennsylvania. He previously held tenured positions at Georgia Tech and the University of Illinois. Prof. Ghrist received a Presidential Early Career Award for Science and Engineering (PECASE) from President Bush in 2004, and was named to Scientific American’s “top 50” for research in 2007. His many contributions focus on contemporary applied mathematics, especially topological methods, where he has been a major force in integrating topological thinking into real world technological situations

Topological Methods for Systems and Signals

Wednesday, May 16 ■ 12:30 ■ Meyer Bldg., Auditorium 1003

[Refreshments at 12:30, the lecture will start at 12:45]

Abstract: This talk will survey some recent advances in a qualitative approach to signal processing using tools from algebraic topology. Topology — the mathematics of qualitative description and local-to-global inference — is an ideal tool-set for several applications in engineering, especially in settings that are coordinate-free or otherwise employ “minimal” types of data. The applications surveyed here will span localization, mapping, aggregation, and optimization in robotics, sensing, and planning.

Professor Ghrist will also deliver a Mathematics Colloquium

Constructible Sheaves and Data

Monday, May 14 ■ 15:30 ■ Amado Bldg., Room 232

(Refreshments at 15:00, in the Math Lounge, 8th floor)
