Welcome to the personal and professional website of Nicholas ( Nick ) Mattei.

I am currently a senior researcher working with Prof. Toby Walsh in the Decision Sciences group at Data61 (formerly known as the Optimisation Group at NICTA).  I am also 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.

Previously, I was a Ph.D student at the University of Kentucky (UK) working with Prof. Judy Goldsmith on AI and Complexity Theory.

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.

I am on the academic job market for 2016!

I am looking for positions in Computer Science at a US based university or research facility.

I will be at AAAI in Phoenix and the University of Kentucky in April.


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.
