Research Overview

Computer Engineering Research at UCSB

CE research lies not only at the interface of computer science and electrical engineering, but increasingly ties computing together with biology, medicine, chemistry, physics, mechanical engineering, and even environmental engineering.

Our research is ideally positioned to help solve societal problems through the construction of practical systems composed of emerging technologies. We live in a time of both opportunity and crisis. Rising carbon emissions and energy costs are a global problem. Aging populations increasingly strain healthcare resources. Computing technologies are at the heart of many potential solutions to these problems. Emerging technologies in nanoscale and bio-compatible materials hold the promise to increase energy-efficiency and revolutionize healthcare. We also see opportunities in massive information gathering and large-scale computing resources to exploit that information.

We must also address increasing challenges to continued scaling of conventional silicon and to maintaining the dramatic performance growth of past computing systems.

Faculty Lab Spotlight

PQRS Computer Architecture Lab

Behrooz Parhami

PQRS imageParhami's research projects entail aspects of computer design and architecture that are captured by the abbreviation PQRS, with each aspect defined by a set of keywords:

  • Performance, incorporates latency, speedup, throughput 
  • Quality, embodies accuracy, parts/energy economy, stability 
  • Reliability, encompasses correctness, timeliness, safety 
  • Scalability, spans modularity, packageability, expandability

In recent years, the focus has somewhat expanded to also include TUVW, as defined below:

  • Testability, during design, implementation, and field use 
  • Usability, while requiring minimal expertise and training 
  • Versatility, to allow mass production for economy of scale 
  • Workability, a synonym for practicality in design and use

Within the rather broad field of computer design and architecture, Professor Parhami's active research interests fall within three subareas:

Tell Us About Your Research: My research focuses on automated verification techniques and their application to software. As computer systems become more pervasive, their dependability becomes increasingly important. As a result, there is an ongoing shift in focus, both in academia and industry, from performance to dependability. The size and complexity of the software systems nowadays inevitably lead to errors during both design and implementation phases. The goal of our research at VLab is to develop verification techniques that will help developers in identifying errors in software. Recently, we have developed a novel approach for finding data model bugs in software applications written using the Ruby-on-Rails framework, where programming errors could lead to loss of data or unauthorized access to data — see research full description

What do you Find Particularly Rewarding about your Research?:

Computing is a young field. It has changed the world already, but this is just the beginning. For years to come, human civilization will be heavily influenced by the advancements in the field of computing. Conducting scientific research in computing is a very fulfilling way to contribute to this future. I am particularly interested in research problems about analyzing software. The core of computing discipline is programming, in other words, writing software. By focusing on software analysis, I get to work on one of the core problems in the field of computing.
