Biography: 

Jeffrey K. Hollingsworth is a professor in the Department of Computer Science. He also holds joint appointments in UMIACS and the Department of Electrical and Computer Engineering.

Hollingsworth’s research seeks to develop a unified framework to understand and optimize the performance of large systems and focuses in several areas. He has developed a new approach, called dynamic instrumentation, to permit the efficient measurement of large parallel applications. Hollingsworth has also developed an auto-tuning framework called Active Harmony, which can be used to tune kernels, libraries or full applications. Additionally, he is investigating the interactions between different layers of software and hardware to understand how they influence performance and how to map data between these layers of abstraction.

Hollingsworth has served on the board of directors of the Computing Research Association. He is editor-in-chief of the journal, Parallel Computing, and is the general chair of the SC12 conference, which is the largest HPC conference in the world with more than 10,000 attendees.

Hollingsworth received his doctorate and MS degrees in computer science from the University of Wisconsin. He received a B.S. in electrical engineering from the University of California, Berkeley. He joined the faculty of the University of Maryland in 1994.
