• Mining Software Archives — What can we predict from the history of changes and errors? (A lot.)
• Automated Debugging — When a program fails, can we automatically determine the cause for the failure? (We can.)
• Mutation Testing — How can we tell whether a test suite is adequate even for large programs? (We can.)
• Mining Models — Can we generate abstractions that capture the common properties of multiple programs or runs? (Yes.)

• 2009-09-21: A new piece on Research and Researchers.
• 2009-07-27: My paper "Yesterday, My Program Worked. Today, It Does Not. Why?" from ESEC/FSE 1999 has been selected to receive this year's ACM SIGSOFT Impact Paper Award. (This paper introduced delta debugging and was one of the first to leverage version histories for program analysis.) Watch my keynote talk!

(I contributed a chapter on "Beautiful Debugging"; all proceedings go to Amnesty International.)
• 2007-12-22: IBM is supporting our project "Mining Jazz Data to Assess Development Processes" with a Jazz Faculty Grant. Thanks!

• My resume has a full record of my projects and publications.
• I have a reputation for being a good presenter. Here's a keynote I was pretty happy with.
• Here is a picture of me in high resolution (2804x3197 pixels).
• Here's a few thoughts on what makes good research and researchers.

• See the top of this page for my address, e-mail, and phone. E-mail me for iChat (AIM) or Skype contacts.
• If you are at the university, please meet me in my office in Building E1 3, Room 303. Official appointment hour (»Sprechstunde«) is Monday 2-3pm, but my office is normally open for visitors all day long.
• To meet me elsewhere, check out my travel plans.
• Here are the directions to my home.

• The chair page holds recent resources for projects and courses.
• Here are some tips on how to give a good research talk.
• On average, I get 7-10 e-mails per week in which people apply for internships or open positions. We do not offer internships, nor do we have open positions right now; and I do not answer mails that are obviously mass mailings.
• I used to have a personal LaTeX style for my presentations (short intro). Today, though, I use and recommend Apple's Keynote.
• Zeller's Clock is a 25-minute countdown inspired by Michael Ernst's Countdown. This can be run by session chairs during a talk on a laptop facing the speaker, so the speaker always knows how much time is remaining. (The name "Zeller's Clock" was not coined by me, but by the participants of a Dagstuhl seminar where it was first used.)
