From March 1997 to September 1999, I was a senior research scientist for the Legion project at the University of Virginia Department of Computer Science. Prior to that I was an assistant professor for one and a half years in the Departamento de Ciencia de Computación (the computer science department) of the Pontificia Universidad Católica de Chile.
My research interests include interactive information retrieval, distributed systems, and operating systems. My technical work at UVa focused on the design and implementation of security for the Legion metacomputing environment.
Currently (late 2013), I am the VP of Engineering at Infinio, a start-up focused on acceleration and increased utilization of virtualized storage. Before Infinio, I was a distinguished engineer at Netezza, which builds massively parallel data warehouse appliances for large-scale data analytics. Netezza is now part of IBM. I was previously a founder and vice president of advanced technology at Endeca, a software company specializing in intuitive information access, later acquired by Oracle. I also co-founded Applied Metacomputing, a spin-off from the University of Virginia to commercialize the Legion technology. Applied Metacomputing was renamed Avaki and eventually acquired by Sybase in April 2005.
