Carole-Jean Wu is an Associate Professor of Computer Science and Engineering in Arizona State University. She holds a Research Scientist position with Facebook’s AI Infrastructure Research. She is a senior member of both ACM and IEEE.

Prof. Wu works in the area of Computer and System Architectures. In particular, her research focuses on high-performance and energy-efficient computer architecture through hardware heterogeneity, energy harvesting techniques for emerging computing devices, temperature and energy management for portable electronics. More recently, her research has pivoted into designing systems for machine learning. She is the leading author of “Machine Learning at Facebook: Understanding Inference at the Edge” which presents unique design challenges faced when deploying machine learning solutions at scale to the edge, from over billions of smartphones in the wild to Facebook’s virtual reality platforms. She is the recipient of the 2018 IEEE ITHERM Best Paper Award, the 2017 NSF CAREER Award, the 2017 IEEE Young Engineer of the Year Award, the 2014 IEEE Best of Computer Architecture Letter Award, the 2013 Science Foundation Arizona Bisgrove Early Career Scholarship, and the 2011-12 Intel Ph.D. Fellowship. Her research has been supported by both industry sources and the National Science Foundation.

She currently serves on the Steering Committee of the IEEE International Symposium on Performance Analysis of Systems and Software and is the Program Chair for the 2018 IEEE International Symposium on Workload Characterization. She is also co-chairing the MLPerf Edge Inference WG. She served on the Executive Committee of the IEEE Technical Committee on Computer Architecture (TCCA) 2017-18. Prof. Wu received her M.A. and Ph.D. degrees in Electrical Engineering from Princeton University. She completed a B.Sc. degree in Electrical and Computer Engineering from Cornell University.

Note to New Students

    If you are a prospective student, please read this note before contacting me about graduate school. I am a faculty member in Computer Science and Engineering in the School of Computing, Informatics, and Decision Systems Engineering of Arizona State University. The department offers graduate degrees in Computer Science as well as Computer Engineering. Therefore, if you are interested in ASU, I encourage you to apply to the degree major that best suits your background and interests.

If you are a student at ASU and are interested in my research work, I encourage you to take my courses (Computer Architecture and/or Advanced Computer Architecture) and perform well in class. In general, I am happy to talk to students who show a sincere interest in understanding my research before expressing a generic interest in working with me.

If you are considering to apply for PhD programs, here is the document “Applying to Ph.D. Programs in Computer Science” written by Mor Harchol-Balter. Reading her document would be very instructive. I am also happy to discuss about graduate school opportunities with students who consider this path.
