I have been a faculty member in the Department of Computer Science since 1998 and a full professor since 2010; I was named a Sohaib and Sara Abbasi Professor in 2020. I have published over 100 technical papers in computational geometry, computational topology, graph algorithms, and related topics at the intersection of computer science and mathematics. Among many other conference committee memberships, I was the chair of the community-elected steering committee for the International Symposium on Computational Geometry (SOCG) from 2013 to 2016, and I am currently a SafeTOC (anti-harassment) advocate for SOCG and for the ACM-SIAM Symposium on Discrete Algorithms (SODA).
I primarily teach large algorithms classes; my free Algorithms textbook is used in dozens of computer science departments and by myriads of of students, recruiters, and professionals around the world. I am an Education Innovation Fellow in the Grainger College of Engineering's Academy of Excellence in Engineering Education. Exactly half of my former PhD students have won NSF CAREER awards. My own awards include a Sloan Research Fellowship, an NSF CAREER award, and numerous teaching and research awards from the University of Illinois.
At various times in my professional life I have been an associate department head (in charge of faculty hiring), the chair of the faculty advisory committee, an Apple II assembly-language programmer, a disk jockey, a pizza cook, and a knot-tying instructor at a Boy Scout camp. My current favorite brands of espresso are Unicorn Blood by Dark Matter and Redacted by Blue Copper. Please see http://jeffe.cs.illinois.edu/cv.pdf for a detailed curriculum vitae.
