Life and Work

Ghrist received in 1991 his bachelor's degree in mechanical engineering from the University of Toledo and in 1994 his master's degree and in 1995 his PhD from Cornell University under Philip Holmes with thesis The link of periodic orbits of a flow.[1] From 1996 to 1998 he was R. H. Bing Instructor at the University of Texas and from 1998 an assistant professor and then from 2002 an associate professor at the Georgia Institute of Technology. In 2002 he became an associate professor and in 2004 a professor at the University of Illinois at Urbana-Champaign. From 2007 he was at the Information Trust Institute. In 2008, he was appointed Andrea Mitchell Penn Integrating Knowledge University Professor in Mathematics and Electrical/Systems Engineering at the University of Pennsylvania.

Ghrist was a visiting scientist in 1995 at the Institute for Advanced Study and in 2000 at the Isaac Newton Institute in Cambridge. He works on the application of topological methods to dynamical systems, robots, hydrodynamics, and information systems, such as sensor networks.[2]

Honors and Awards

In 2002 Ghrist received a Presidential Early Career Award. In 2013 he received the Chauvenet Prize for Barcodes: The Persistent Topology of Data[3] and in 2014 the Gauss Lectureship of the German Mathematical Society.

gollark: You can convince this sort of person to leave you alone by reciting a complete description of Macron to them.
gollark: This would miss unusual meanings, but we can't do much about that without accursed ML things of some sort.
gollark: The formulae seem to be based on word length and other such badness, but we have computers now, so a lookup table for word weirdness is very practical.
gollark: I'd probably try and do it based on grammatical nesting level and commonness of words.
gollark: ddg! Analytic vs infinitely differentiable
