About Me...

My research interests focus mainly on topics in machine learning especially evolutionary computation although I'm also keenly interested in programming language and software engineering issues. I've recently become interested in the data science movement because of my background in both programming, machine learning and statistics.

"If you have an idea that is obviously wrong, find a cheap way to test it because if it works, it's interesting. Obviously correct ideas have probably been thought of by someone else" --Kent Beck
