Dr. Julien is an associate professor in the Center for Advanced Research in Software Engineering (ARiSE) in the Department of Electrical and Computer Engineering at the University of Texas at Austin, which she joined in 2004. She is the director of the Mobile and Pervasive Computing Group, where her research focuses on the intersection of software engineering and dynamic, unpredictable networked environments. Her specific focus is on the development of models, abstractions, tools, and middleware whose goals are to ease the software engineering burden associated with building applications for pervasive and mobile computing environments. Dr. Julien's research has been supported by the National Science Foundation (NSF), the Air Force Office of Scientific Research (AFOSR), the Department of Defense, and Freescale Semiconductors. The work has been recognized by an NSF CAREER award and an AFOSR Young Investigator Award, and the results have appeared in many peer reviewed journal and conference papers. Dr. Julien graduated with her D.Sc. in 2004 from Washington University in Saint Louis, where her doctoral research under the supervision of Dr. Gruia-Catalin Roman focused on developing a middleware called EgoSpaces that provided an intuitive data-structure abstraction to support application coordination in mobile computing environments. She earned her M.S. degree in 2003 and her B.S. with majors in Computer Science and Biology in 2000 (both also from Wash. U.).

B.S. in Electrical and Computer Engineering, University of Illinois at Urbana-Champaign, 2011

Tomasz's research interests include content-based publish/subscribe systems for routing in delay-tolerant networks. He is currently interested in using context information (extracted from existing routing protocols) in order to increase the efficiency of content-based routing for delay-tolerant networks that have hard resource constraints.

B.S. in Electrical Engineering, University of Pennsylvania, 2007

Kate's research interests lie in the intersections of smart grid, pervasive computing, and machine learning. She is currently focused on developing an autonomous thermostat control agent that balances a user's desired comfort range with a monthly budget for heating and cooling costs. Her research is funded by an NSF IGERT traineeship in Sustainable Grids, at the heart of which is a partnership with Pecan Street Inc.
