I am the leader of the Trust Laboratory
at The University of Texas at El Paso (UTEP)
, a member of The Software Engineering Affinity Laboratory
, and a member of UTEP's Cyber-ShARE Center of Excellence for Sharing Resources Through Cyber-Infrastructure
to advance science, engineering, and education. Cyber-ShARE is a National Science Foundation (NSF)
-funded multi-disciplinary research effort between computer science, geosciences, environmental sciences, computational math, astronomy, and education.
At Cyber-ShARE, I am the leader of the computer science component that aims to increase the scientist use of semantic web
and social network technologies in support of cyber-infrastructure-based, data-intensive applications and services. In particular, the center aims to provide scientists with information that will enable them to make informed decisions about retrieved resources and to have confidence in using resources derived through complex scientific processes.
I am a co-leader of the Inference Web (IW)
project, a collaborative research effort between UTEP, Stanford University
, and Rensselaer Polytechnic Institute
. The IW project aims to provide infrastructure for explaining answers from software systems. Inference Web has been sponsored by a number of DARPA, NSF, DHS and DTO (formerly known as ARDA) projects.
Prior to joining UTEP, I was a postdoctoral fellow in the Knowledge Systems, AI Laboratory
at Stanford University. I am a former member of the Information Management Group
at the School of Computer Science
of the University of Manchester
, United Kingdom, a leading research group on Semantic Web, Grid and e-Science solutions in Europe. I am also a former member of the Database Group
at the Universidade Federal de Minas Gerais (UFMG)
, Brazil, a leading research group on information extraction and information retrieve in Latin America.
