Howdy! I am a Research Staff Member at the IBM TJ Watson Research Laboratory in the Cognitive Computing Group.  My research is broadly in artificial intelligence (AI) and its applications; I am motivated by problems that require a blend of techniques to develop systems and algorithms that support decision making for autonomous agents and/or humans. Most of my projects and leverage theory, data, and experiment to create novel algorithms, mechanisms, and systems that enable and support individual and group decision making.

Along with Prof. Toby Walsh, I am the founder and maintainer of PrefLib: A Library for Preferences.   So check it out at www.PrefLib.org for lots of great preference data and PrefLib-Tools on GitHub for more data wrangling tools.  We also have had a great time with our Exploring Beyond the Worst Case in Computational Social Choice (EXPLORE) series held at AAMAS in 201420152016, and (soon) 2017.

Previously, I was a senior researcher working with Prof. Toby Walsh in the AI & Algorithmic Decision Theory Group at Data61, formerly known as the Optimisation Group at NICTA, a unit of the Commonwealth Scientific and Industrial Research Organisation (CSIRO).  I am (still) an adjunct lecturer in the School of Computer Science and Engineering (CSE) and member of the Algorithms Group at the University of New South Wales in beautiful Sydney, Australia.  Before that, I was a Ph.D student at the University of Kentucky (UK) working with Prof. Judy Goldsmith on AI and Complexity Theory. And in the way olden days I worked for the National Aeronautics and Space Administration (NASA) Ames Research Center designing embedded hardware and software flight systems for nano-satellites.

In another life I drove trucks full of carnival prizes all over central Kentucky and Indiana … you don’t know fun till you’ve delivered several hundred pounds of stuffed animals to shooting booths at remote county fairs.

Some Current Things You Should Submit To!

I am currently on the Senior Program Committee for AAMAS 2017 and the Program Committee for AAAI 2017, FLAIRS 2017IJCAI 2017, and ADT 2017 — consider submitting if you are working on AI or decision theory!!

In conjunction with ACM SIGAI I am organizing the ACMSIG AI Student Essay Contest on the Responsible Use of AI Technologies.  We have great prizes!! Please encourage your students to submit!

I am also co-organizing the 4th Workshop on Exploring Beyond the Worst Case in Computational Social Choice (EXPLORE 2017) @ AAMAS 2017!

I am also on the DC committee for ADT 2017 — encourage your students to apply!
