Professor, Computer Science

Professor Benson's research areas include operating systems, parallel computing, and programming languages. He has designed and developed several run-time systems and tools for parallel programming languages and libraries. Specifically, he led the development of USFMPI, a multi-threaded implementation of MPI 1.2 for Linux using either Myrinet or Ethernet. In addition, Professor Benson co-created FlashMob Computing and he implemented much of the software that enabled the harnessing of 700 volunteer computers in a single day at the USF gym to run HPL (Linpack). He is currently working on River, a Python-based framework for rapid prototyping of reliable parallel run-time systems. Professor Benson received his Ph.D. in computer science from the University of California, Davis. While he was a graduate student, he held visiting research positions with the Orca research group at Vrije University in the Netherlands and with the Flux OS research group at the University of Utah.

Professor (Emeritus), Computer Science/Mathematics

Cruse attended college at Emory University where he majored in mathematics. He was awarded a fellowship for graduate study at UC-Berkeley by the Woodrow Wilson Foundation on condition that he agree to give "serious consideration‚" to pursuing a career in college teaching, and after finishing his Master's Degree at Berkeley, he accepted USF's offer in 1966 of a "temporary" position teaching classes in mathematics: that position morphed into a permanent one after he completed his mathematics doctorate, awarded by Emory University in 1974. Professor Cruse began teaching computer science courses over two decades ago, soon after USF acquired its first UNIVAC 90/60 mainframe. His current research interests are in the areas of systems programming for microcomputers and processor virtualization.

Associate Professor, Computer Science

Professor Joshi's research interests are in the field of scientific visualization, medical imaging and illustration-inspired techniques for visualization. His work has led to novel visualization techniques in fields as diverse as computational fluid dynamics, atmospheric physics, medical imaging and cell biology. Through the illustration-inspired visualization techniques that he developed, atmospheric physicists are able to visualize the time-varying nature of hurricanes more effectively. Some of his current work deals with developing and evaluating the performance of neurosurgeons on novel visualization and interaction techniques. Professor Joshi received his Ph.D in Computer Science from the University of Maryland Baltimore County and completed his postdoctoral research at Yale University. He has also worked with industry partners such as VitalImages Inc., Electrical Geodesics and Siemens Corporate Research. .
