Biographical Sketch
Patricia received her Ph.D. (2019) and M.Sc. (2015) from the University of Virginia, Charlottesville, VA, USA; and her Bachelors Degree from the Pontifical Xavierian University (2008), Bogota, Colombia. She also worked as an ASIC Design and Verification Engineer in Hewlett-Packard, Costa Rica.
Her research interests include ultra-low power VLSI digital and mixed-signal design. Her work focuses on non-conventional computing paradigms to reduce power and energy consumption, such as, synchronous and asynchronous stochastic computing, computing with sigma-delta streams and race logic.
Current Projects
- Project 38: A set of vendor-agnostic architectural explorations involving NSA, the DOE Office of Science, and NNSA
- Superconducting Race Logic Accelerators: Make computation in superconducting circuits, circuits that operate around 4K temperatures and have close to zero resistance, as efficient as possible
