Daniel Ángel Jiménez

For a detailed list of professional things I've done, see my CV.

I am back from my leave at the Barcelona Supercomputing Center. It was very nice.

HPCA 2011

As of 2009 I have left my job as associate professor with tenure in the Department of Computer Science at Rutgers so I could eat more tacos.

Old Stuff

• 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.
