My research interests include topics in machine learning, artificial intelligence, algorithmic game theory and microeconomics, computational social science, and quantitative finance and algorithmic trading. I often examine problems in these areas using methods and models from theoretical computer science and related disciplines. While much of my work is mathematical in nature, I also often participate in empirical and experimental projects, including applications of machine learning to problems in algorithmic trading and quantitative finance, and human-subject experiments on strategic and economic interaction in social networks.

Aaron Roth and I have written a general-audience book about the science of designing algorithms that embed social values like privacy and fairness; here is the publisher's description:
Over the course of a generation, algorithms have gone from mathematical abstractions to powerful mediators of daily life. Algorithms have made our lives more efficient, more entertaining, and, sometimes, better informed. At the same time, complex algorithms are increasingly violating the basic rights of individual citizens. Allegedly anonymized datasets routinely leak our most sensitive personal information; statistical models for everything from mortgages to college admissions reflect racial and gender bias. Meanwhile, users manipulate algorithms to "game" search engines, spam filters, online reviewing services, and navigation apps.
Understanding and improving the science behind the algorithms that run our lives is rapidly becoming one of the most pressing issues of this century. Traditional fixes, such as laws, regulations and watchdog groups, have proven woefully inadequate. Reporting from the cutting edge of scientific research, The Ethical Algorithm offers a new approach: a set of principled solutions based on the emerging and exciting science of socially aware algorithm design. Michael Kearns and Aaron Roth explain how we can better embed human principles into machine code - without halting the advance of data-driven scientific exploration. Weaving together innovative research with stories of citizens, scientists, and activists on the front lines, The Ethical Algorithm offers a compelling vision for a future, one in which we can better protect humans from the unintended impacts of algorithms while continuing to inspire wondrous advances in technology.

PUBLICATIONS:BOOKS
PUBLICATIONS: RESEARCH ARTICLES
What follows is a listing of (almost) all
of my research papers in (approximately) reverse
chronological order. For papers with both a conference and journal version,
the paper is usually placed by its first (conference) date.
Also, as per the honorable tradition of the theoretical computer science community, on almost all of the
papers below that are primarily mathematical in content, authors are listed alphabetically.
Acronyms for conferences and journals include:
AAAI: Annual National Conference on Artificial Intelligence;
AIES: AAAI/ACM Conference on Artificial Intelligence, Ethics and Society;
AISTATS: International Conference on Artificial Intelligence and Statistics;
ALT: Algorithmic Learning Theory;
COLT: Annual Conference on Computational Learning Theory;
EC: ACM Conference on Economics and Computation;
FAccT: ACM Conference on Fairness, Accountability and Transparency (formerly FAT* and FATML);
FOCS: IEEE Foundations of Computer Science;
HCOMP: AAAI Conference on Human Computation and Crowdsourcing;

In addition to the list below,
you can also look at my page on
Google Scholar,
and this
DBLP query
seems to do a pretty good job of finding those publications that appeared in mainstream CS venues (though not others),
and can be useful for
generating bibtex citations.
NOTE:
The main result of the paper above --- an efficient algorithm claimed to find a
single
exact
Nash equilibrium in tree graphical games --- is unfortunately
wrong.
This was discovered and discussed in the very nice paper by Elkind,
Goldberg and Goldberg, which can be found
here.
The problem of efficiently computing an exact Nash equilibrium in trees remains open (though
EG&G demonstrate that no two-pass algorithm can suffice). The
original polynomial-time
approximate
Nash algorithm from the K., Littman, Singh UAI 2001 paper
is unaffected by these developments, as is its NashProp generalization in the
Ortiz and K. 2002 NIPS paper.
