Howdy! I am a Research Staff Member at the IBM TJ Watson Research Laboratory in the IBM Research AI – Reasoning Lab.  My research is broadly in the theory and practice of artificial intelligence; 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.  I try to make as much of the code and data available through PrefLib and GitHub.

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 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 2018 and the Program Committee for AAAI 2018, FLAIRS 2018IJCAI 2018, and AIES 2018 — consider submitting if you are working on any aspects of AI, decision theory, ethics of artificial intelligence, or theory!!

I am co-organizing the 11th Multidisciplinary Workshop on Advances in Preference Handling @ AAAI 2018!

I am co-organizing the 1st Doctoral Program on AI, Ethics, and Society at the 1st International Conference on AI, Ethics, and Society!
