  1. 1. Ron Kohavi, PhD ronnyk@CS.Stanford.EDU Work Experience 2005- Product-Unit-Manager, (Seattle, WA). 2003-2005 Director, Data Mining and Personalization, (Seattle, WA). Manage multiple teams in a 65-person organization responsible for Amazon’s personalization, automation, consumer behavior / data mining, site experimentation, and automated e-mail. Introduced several features estimated to be worth several hundred million dollars in incremental revenue. 2002-2003 Vice President, Business Intelligence, Blue Martini Software (San Mateo, CA) Managed the Business Intelligence Sales Demo team and the Analytic Services team. Helped drive Business Intelligence sales and marketing activities, created success stories, and helped the professional services organization in complex implementations as a center of excellence. Senior director, Data Mining Applications, Blue Martini Software Led the engineering team, including two managers. Responsible for the data 2000-2002 collection, transfer (ETL), analysis, reporting, visualization, and campaign management in Blue Martini's products. Director, Data Mining Applications, Blue Martini Software Designed and architected the data mining, reporting, and transfer (ETL) modules. 1998-2000 Led the engineering team responsible for these components. 1997-1998 Manager, MineSet, Silicon Graphics Inc. (Mountain View, CA) Managed the MineSet data mining and visualization engineering team of 15, including another manager. 1996-1997 Manager, Analytical Data Mining group, MineSet, Silicon Graphics Inc. Managed a team of five engineers that designed and implemented the analytical (server-side) data mining engines of MineSet on top of MLC++. 1995-1996 Project lead, MineSet, Silicon Graphics Inc. Designed and implemented data mining algorithms for MineSet using MLC++. 1993-1995 Project lead, MLC++, Stanford University. Designed and Implemented the Machine Learning library in C++ for data mining. Supervised four students, including one 50% research assistant dedicated for the project. The library was adopted as the basis for the analytical engines in MineSet when I moved to SGI and later licensed by Blue Martini Software.
