Welcome to RTDS!

RTDS lab belongs to the systems and interdisciplinary research areas of the Department of Computer Science and Engineering. In addition to our research in computer systems, we are extensively engaged in interdisciplinary research. Computer system research  gives us technology strengths, and the interdisciplinary research  uses the strength to improve the world. Some research topics being actively pursued include, but are not limited to

  • GPU acceleration of Privacy-Preserving Protocols
  • Collaborative workforce behaviors
  • Geo-analysis of low level conflicts (MECH)
  • Complex pattern matching
  • RF signals analysis
  • Binary analysis
  • Health and wellbeing technology

This web site offers the viewer some insights on our recent activities, helpful tips and resources, as well as related fields. We also plan to start a forum for the community to elaboreate and disscuss contemporary technical issues. Please stay tuned when it is ready for on-line access.

About the artwork:  RTDS tapestry

RTDS is a vision coined  by the lab director two decades ago as a then “future generation”  of time-coordinated large scale computing capabilities for computers distributed at a distance.   Satellite based time and position RF signals, together with inexpensive, high-performance computer devices make RTDS a reality for many contemporary applications, e.g., smart power grid, network security, sensing arrays, even global high performance transactions. RTDS constantly reminds us of our root, yet in two decades our research has expanded into a  broad profile of systems and interdisciplinary topics.  The artwork “RTDS tapestry” gives a snapshot  of knowledge discoveries made by lab members. As noticed by a lab member,  despite their complex appearances, our work were propelled by a few powerful mathematical frameworks, coupled with optimized algorithms and architectures to serve significant applications. One step at a time, one may say that we are taking a data driven research process to understand and uncover the tapestry  of new knowledge in the Cyber and Physical Systems (CPS). Without understanding their underlying complexity, one cannot appreciate the magnificence and beauty of  nature’s laws. The lifelong journey marches on.
