Professor Geoff Holmes headed the highly successful machine learning group at the University of Waikato for more than a decade, and has been involved in several open source projects over the last 20 years.
He has made contributions in machine learning across several branches of the subject and has been active in finding ways to reward researchers for their efforts to produce open source software.
In this regard he acts as an action editor for the branch of JMLR dedicated to open source software. He has a history of developing applications of machine learning, particularly in the agricultural sector, and was part of the team that in 2005 won the SIGKDD Data Mining and Knowledge Discovery Service Award for Weka.
He regularly serves on senior program committees for major conferences in machine learning and data mining and since 2006 he has been working on the MOA (Massive Online Analysis) Project making contributions to Big Data Analytics.
