Jeff Erickson's ResearchMy main research interests are computational geometry, computational topology, and graph algorithms. Specific problem areas I have worked on include basic questions in combinatorial geometry and topology; analysis of realistic geometric inputs; geometric range searching; algorithms for continuously changing data; flows, cuts, shortest paths, and other structures in planar and surface graphs; and applications of geometry and topology to combinatorial optimization, computer graphics, robotics, spatial and temporal databases, and mesh generation.
Almost all of my research has been supported by the National Science Foundation, under an Mathematical Sciences Research Postdoctoral Fellowship, a CAREER award (CCF-0093348), and several other grants (DMR-0121695, CCF-0219594, DMS-0528086, CCF-0915519, OCI-0948393, CCF-1408763, and CCF-1725544). I was also supported by a Sloan Research Fellowship from 1999 to 2002.

My local colleagues
- I work with fantastic graduate students; currently, Christian Howard, Patrick Lin, and Yipu Wang
- I have been area chair of the CS department's algorithms and theoretical computer science research group.
- Other Illinois faculty (past and present) whose academic interests overlap mine include Bob Haber (now retired), Chandra Chekuri, Doug West (now retired), Edgar Ramos (now in Colombia), George Francis (now retired), Ilya Kapovich, Jean Ponce (now at INRIA/ENS), John Hart, John Sullivan (now at TU Berlin), Michael Garland (now at NVIDIA), Nathan Dunfield, Rob Ghrist (now at Penn), Sariel Har-Peled, Seth Hutchinson (now at Georgia Tech), Steve LaValle (now at Oulu, Finland), and Timothy Chan.
My global colleagues
- Twelve of my former students have graduated with PhDs:
- Alper Üngör (PhD 2002), who I
stole fromco-advised with Shang-Hua Teng, is an associate professor of computer science at the University of Florida, Gainesville. Alper won an NSF CAREER award in 2009.
- My first academic grandchild Hale Erten (PhD 2009, Florida) works in the computational lithography group at Intel Oregon.
- Shripad Thite (PhD 2005) is a software engineer at YouTube.
- David Bunde (PhD 2006) is an associate professor and the chair of the Department of Computer Science at Knox College. That makes David my first student to outrank me.
- Dan Cranston (PhD 2007) is an associate professor of mathematics at Virginia Commonwealth University. I was Dan's MS advisor; Doug West was his PhD advisor.
- Erin Chambers (PhD 2008) is a full professor of computer science at St. Louis University. Erin won an NSF CAREER award in 2011.
- Feida Zhu (PhD 2009) is an assistant professor of information systems at Singapore Management University. I was Feida's advisor for his first few years at Illinois, before he found his real voice working with Jiawei Han.
- Kevin Milans (PhD 2010) is an associate professor at the University of West Virginia University. I was Kevin's MS advisor; Doug West was his PhD advisor.
- Amit Patel (PhD 2010, Duke) is an assistant professor of mathematics at Colorado State University. I was Amit's MS advisor; Herbert Edelsbrunner was his PhD advisor at Duke.
- Amir Nayyeri (PhD 2012) is an assistant professor at Oregon State University.
- Pratik Worah (PhD 2013, Chicago) works at Google in New York. I was Pratik's MS advisor; Janos Simon was his PhD advisor at the University of Chicago.
- Kyle Fox (PhD 2013) is an assistant professor of computer science at UT Dallas.
- Hsien-Chih Chang (PhD 2018) is a postdoc in computer science at Duke.

- I can still lower my Erdös number, but not without writing another paper.
I came in late to Jeff Erickson's 8:30 pm talk on "Lower Bounds in Computational Geometry." Jeff's a CS grad student at Berkeley, and when I emailed Yarvin to ask if he knew this guy Jeff who did theoretical computational geometry, he responded, "Theoretical computational geometry makes me ill."
