(You're trying to access my old web page at UT. Here's kind of what my updated web page at Rutgers looks like. If you must see the old web page, click here.)

I'm an assistant professor in the computer science department at Rutgers . I'm interested in anything related to making computation go faster. My focus is on microarchitecture and the interaction between the compiler and the microarchitecture. I've been doing a lot of work in branch prediction.

Note: I am currently on sabbatical leave at the Department of Computer Architecture at the Technical University of Catalonia in Barcelona, Spain.

Java CoCo Emulator

I have been developing an emulator for the Tandy Color Computer in Java. Click here to start the emulator and see what I have done so far. I take no responsibility if your browser crashes :-). This link will probably disappear soon.

Old Stuff

In my previous life, I was a graduate student at the University of Texas at Austin, I worked on the faculty of the UT Health Science Center at San Antonio medical school, and taught computer science classes at UTSA. Here are local copies of the web pages I kept then:

Grad Student, The University of Texas at Austin. My advisor was Calvin Lin. My thesis title was Delay-Sensitive Branch Predictors for Future Technologies.
Instructor/Research, The Department of Rehabiliation Medicine, The University of Texas Health Science Center at San Antonio I did research at UTHSCSA into automating the design of prosthetic devices for below-the-knee amputees. Here's a Java applet I wrote that shows the shape of an amputee's leg with anatomical markers. Part of my job was to find these markers using neural networks.
Teaching Associate, The Division of Computer Science, The University of Texas at San Antonio These pages relate to the classes I taught while at UTSA. They have some information that might be useful to undergraduates in CS, as well as anyone teaching similar CS courses.

Quotes

I have collected a few interesting quotes here.
