Personal Information

I like programming the iPhone, building and playing ukuleles, folding origami, listening to podcasts, reading (to myself and my kids), playing board games, and watching Doctor Who (when I have the time).

Web Resources

Here are a few of my favorite biomedical text mining resources on the Web:

• BLIMP (Biomedical Literature and Text Mining Publications), a forum for collection, compilation, and exchange of publications on biomedical text mining.
• Alex Morgan's page on BioNLP resources, although it has been a while since it has been updated.
• TREC Genomics Track home page.
• BioPython project home page. Not geared specifically to text mining BioPython contains lots of tools for working with resources useful in biomedical text mining.
• Python.org, the home of the Python language. You do know about Python, right? After spending years getting paid to program in Assembly, C, C++, and Java, I now do almost all of my text mining research using Python. It's my favorite language.
