BRIEF BIO
Professional (for talk anouncements etc.):
Vincent Conitzer is Professor of Computer Science (with affiliate/courtesy appointments in Machine Learning, Philosophy, and the Tepper School of Business) at Carnegie Mellon University, where he directs the Foundations of Cooperative AI Lab (FOCAL).

Previous to joining CMU, Conitzer was the Kimberly J. Jenkins Distinguished University Professor of New Technologies and Professor of Computer Science, Professor of Economics, and Professor of Philosophy at Duke University. He was also the Head of Technical AI Engagement at the Institute for Ethics in AI, and Professor of Computer Science and Philosophy, at the University of Oxford. He received Ph.D. (2006) and M.S. (2003) degrees in Computer Science from Carnegie Mellon University, and an A.B. (2001) degree in Applied Mathematics from Harvard University.

Conitzer has received the ACM/SIGAI Autonomous Agents Research Award, the Social Choice and Welfare Prize, a Presidential Early Career Award for Scientists and Engineers (PECASE), the IJCAI Computers and Thought Award, an NSF CAREER award, the inaugural Victor Lesser dissertation award, an honorable mention for the ACM dissertation award, and several awards for papers and service at the AAAI and AAMAS conferences. He has also been named a Guggenheim Fellow, a Sloan Fellow, a Kavli Fellow, a Bass Fellow, an ACM Fellow, a AAAI Fellow, and one of AI's Ten to Watch. He has served as program and/or general chair of the AAAI, AAMAS, AIES, COMSOC, and EC conferences. Conitzer and Preston McAfee were the founding Editors-in-Chief of the ACM Transactions on Economics and Computation (TEAC). With Jana Schaich Borg and Walter Sinnott-Armstrong, he authored "Moral AI: And How We Get There" (2024).

Personal: I grew up in Amsterdam, the Netherlands. Besides working and spending time with my wife and kids, I enjoy sports, in the past mostly tennis and judo, and more recently mostly soccer and running, all very much at a recreational level...

IJCAI 2011 Computers and Thought talk: slides without animation, slides with animation. The paper for my AAAI 2012 "What's Hot" talk covers similar material as the talk (but is more up to date). For an overview of some other work, maybe see my 2010 CACM article.

Computational Social Choice tutorial from the 2012 Summer School on Algorithmic Economics at CMU: ppt, pdf. (Earlier versions at COMSOC-10 (ppt, pdf) and with Ariel Procaccia at EC-10 and AAMAS-10 (my slides (ppt, pdf), Ariel's slides).)

My (outdated) intellectual development statement for Duke.

Tutorial: Automated Mechanism Design: Approaches and Applications (ppt (my slides only), pdf (also including Eugene's slides)). Given at EC-08, AAMAS-09, IJCAI-09 with Yevgeniy (Eugene) Vorobeychik.

Attracting Students to Computer Science Using Artificial Intelligence, Economics, and Linear Programming (.ppt, .pdf). (Invited talk at the 2008 AAAI Spring Symposium on Using AI to Motivate Greater Participation in Computer Science, and a 2010 ARTSI faculty workshop.)

Tutorial: Mechanism Design for Multiagent Systems (.ppt, .pdf). Given at the Dubai Agents & Multi-Agent Systems School 2008, and an earlier version at NESCAI 2006.

A game-theoretically optimal computer player for a class of Liar's Dice games (source code). Let me know if you find bugs/have comments. (Apologies for the archaic text-based interface...)

A puzzle - let me know if you solve it. Here are some hints, as well as the first few steps of the solution, and even a translation into French by Dany Bergeron. (For more puzzles, see SIGecom Exchanges.)

A 5-line integer program formulation for Sudoku in GMPL, the modeling language for GLPK (GNU Linear Programming Kit). (I'm certainly not the first to come up with such a formulation, e.g. here.) The example puzzle is from Wikipedia's Sudoku page (and solves in 0.0 seconds).

"Contizer" is the most common misspelling of my family's name; I wonder what causes this particular typo (rather than others with the same edit distance)? Of course, this is nothing compared to the misspellings of "Atila Abdulkadiroglu".
