Kreylos is also affiliated with the UC Davis W.M. Keck Center for Active Visualization in the Earth Sciences KeckCAVES.


Glenda Gaines received a bachelor’s degree in Political Science from University of California, San Diego. 

Having studied international politics and from the standpoint that all things are political—from the votes we cast, to the food we eat, to the shelter we seek—I have found it is the art of governance that maintains the ability to not only define the human condition but improve upon it.  – Glenda Gaines 

Jared JosephGraduate Student Researcher

Jared Joseph is a Ph.D. candidate in sociology with an emphasis in computational social science. His work focuses on corruption in government and the ways actors within the state exploit their government positions. Jared has worked for programs in the US and UK governments using combining data science and sociological theory. Jared is responsible for communications and outreach at the DataLab.

Faculty Directors

Titus BrownAssociate Professor of Veterinary Medicine

Professor Brown serves as DataLab’s Director for Community Engagement.  The Brown lab focuses on genomic, transcriptomic, and metagenomic sequence analysis. The lab is the primary developer of the khmer software, for faster and more efficient sequence analysis of high-throughput sequencing data. They also run quite a bit of training in data-intensive biology. Professor Brown serves on DataLab recruitment committees, teaches workshops, leads hackathons, and participates in our strategic activities and planning. His lab also runs the “Meet and Analyze (biological) Data” (aka MAD) weekly drop-in office hours.

Vladimir FilkovProfessor of Computer Science

Professor Filkov serves as DataLab’s Director for Translational Data Science.  He is a data scientist specializing in a number of applied areas including Empirical Software Engineering, Systems Biology and Gene Networks in Plants, Applied Network Theory, and Data Mining and Algorithms.

Bala RajaratnamProfessor of Statistics

Professor Rajarantnam serves as DataLab’s Director for Research.
