Brief Biography  CV

Ulya R. Karpuzcu serves as an assistant professor at the Department of Electrical and Computer Engineering of University of Minnesota since Fall 2012. She received the Ph.D. and M.S. degrees in Computer Engineering from University of Illinois, Urbana-Champaign. Her research focuses on the impact of process technology on computer architecture, with the current emphasis being on boosting the energy efficiency of computing.


News 

  1. [July MMXVII] Karpuzcu, Sapatnekar, Wang received an NSF SPX grant on scalable in-memory processing using spintronics.

  2. [January MMXVI] Karpuzcu received the NSF CAREER Award on “Trading Communication and Storage for Computation to Enhance Energy Efficiency”.

  3. [June MMXV] We released ACCURAX, a compilation of safe accuracy metrics for approximate computing, along with an output randomization tool.

  4. [September MMXIV] Karpuzcu received an NSF CCF grant on soft (approximate) near-threshold voltage computing.

  5. [August MMXIV] Lilja, Sartori, and Karpuzcu received an NSF XPS grant on approximate communication to enhance energy efficiency.

  6. [January MMXIV] The second Workshop on Near-threshold Voltage Computing will be held w/ ISCA. [Call for Papers]

  7. [Spring MMXIV] New Course Announcement: EE8950 Physics of Computation [Syllabus]

  8. Inspired by Richard Feynman’s lectures, “Physics of Computation” explores how physical principles/limits shape paradigms of computing.

  9. Goal: To understand how (and to what extent) a paradigm shift in computing can help with emerging energy problems.   

  10. Scope: Physical limits of computing, coding and information theoretical foundations, computing with beyond-CMOS devices, reversible computing,

  11. quantum computing, stochastic computing. For each computing paradigm, we cover (i) how information is represented, processed, stored, and communicated;

  12. (ii) to what extent shortcomings can be addressed; (iii) how the application domain looks like.

  13. [September MMXII] We are organizing the first Workshop on Near-threshold Voltage Computing w/ MICRO. [Call for Papers]
