Welcome to my home page

I am a Professor and the Ph.D. Program director with the Department of Computer Science at Texas State University. My main research interests are in knowledge or service discovery, internet of things, health informatics, scientific workflows, databases, software engineering and agent technologies. I have worked in different countries as a researcher, including Institute of Systems Science in Singapore, Tilburg University in the Netherlands, CSIRO (Data61) in Australia, Telcordia Technologies, Lawrence Livermore National Laborartory, and the Microelectronics and Computer Technologies Corporation (MCC) in Austin, Texas.

From 1992-2000, I was a Senior Lecturer in the School of Computer Science and Engineering, University of New South Wales (UNSW), Sydney, Australia where I specialized in teaching databases and performing research in next generation database systems. I also held an adjunct Associate Professor position at UNSW from 2002-2006 and a visiting scholar position at University of California, Berkeley in the fall of 2015.

My research have been funded by the National Science Foundation, Lawrence Livermore National Laboratory, Pacific Northwest National Laboratory, and Australian Research Council.

I was a receipent of the national NCWIT Undergraduate Research Mentoring Awards in 2013. The National Center for Women & Information Technology (NCWIT) created this award to recognize computing professors for their outstanding mentorship, high-quality research opportunities, and efforts to encourage and advance undergraduates (particularly women and minorities) in computing-related fields.
