Tim Sherwood

Faculty Collaborator

At UCSB, Dr. Sherwood co-direct the CS Computer Architecture Lab (ArchLab), where his students and he work on all manner of computer architecture problems, from circuits to systems to the applications that run on them. Computer architecture is a great field in that you can use theory, algorithms, and VLSI all together to attack interesting problems. Dr. Sherwood's primary interest is in techniques that allow for the continuous streaming analysis of complex systems. Whether you are trying to find run-time phases, discover suspicious content in the network, handle wireless multipath interference, or uncover bugs in a program -- modern programmable processors are ill equipped to handle these irregular throughput driven applications. The ArchLab website, and his personal webpage both have more information if you are interested.
