Advisory Group

MacKenzie Smith, University Librarian at UC Davis
MacKenzie Smith creates and leads the strategic vision for the UC Davis libraries and oversees operations for the university’s four main libraries (Shields, Physical Sciences & Engineering, Carlson Health Sciences, and Blaisdell Medical). She leads the library’s efforts to integrate digital resources an information technology to serve the university’s academic community. She has published on information technology and digital knowledge management, and works toward creating and sustaining efforts that enhance efficient and effective access to knowledge. Smith leads the DSI advisory group.


Hemant Bhargava, Professor, MBSA Program Chair, Jerome and Elise Suran Chair in Technology Management.
Professor Bhargava is an expert in technology management and the information technology industry. He also studies the use of IT in clinical health care, and has previously worked on data-driven and analytical decision making in organizations.


Colin Cameron, Professor of Economics.
Professor Cameron’s research speciality is economic theory and microeconmetrics for cross-section data, especially count data, with applications to labor and health economic data.


John Daniels, Statistical Programming Consultant and Systems Administrator for the Social Science Data Service.
John Daniels maintains the SSDS central research systems and provides consulting for statistical and mathematical software applications used by social scientists. He has a background in political science and has worked for over 20 years in the fields of information technology and quantitative research support.


Paul Dodd, Associate Vice Chancellor for Interdisciplinary Research and Strategic Initiatives.
Dr. Dodd’s background is in nanoscale materials science and applied physics, and has worked at the interface of industry, academia for over 20 years.

In Memoriam

Louise Kellogg, Professor of Geophysics and Director of Computational Infrastructure for Geodynamics. Professor Kellogg studied the dynamics of the solid Earth and similar planets, focusing on mantle convection and crustal deformation using computational models rooted in observation. She established the W. M. Keck Center for Active Visualization in Earth Sciences (KeckCAVES) where her research includes interactive visualization of data from natural disaster sites, reconstructing paleoocean flow, and using virtual reality and augmented reality for research and outreach. Professor Kellogg was engaged with the establishment of DataLab’s precursor, the Data Science Initiative.
