Jose Javier Gonzalez Ortiz

I am a PhD student at MIT CSAIL in the CAML group, advised by John Guttag. Before joining MIT, I received a BSc in Telematics Engineering from ICAI in Spain. During my undergrad I interned at CERN Openlab and studied for one year at the University of Michigan, Ann Arbor under an exchange program.
My research interests lie at the intersection of machine learning and computer systems. I'm interested both in building systems for that enable new machine learning methods as well as using machine learning to improve complex computer systems. I recently developed ShrinkBench, a library to facilitate development and standardized evaluation of neural network pruning methods. In the past, I have worked in machine learning and computer vision for healthcare applications.
