Projects
In 2003, with two other UC Irvine graduate students, I co-created JUNG, a free and open-source Java software library for manipulating, analyzing, and visualizing network data. It's one of the top 2 Java open-source graph libraries, and is used widely in both industry and academia; to date it's been downloaded more than 300,000 times.
In 2015, I released a new Java graph library as part of Google's Guava libraries; it is also used widely. The next version of JUNG (in development) will replace its graph model with Guava's.
