View Carlos Villavieja's profile [PDF Resume]About me

I'm a software engineer at Google with a strong background on Hardware so I basically consider a person who likes computers, tries to build, program and use them at all levels.

I was a postdoc at the ECE department at the University of Texas at Austin (from October 2011 to June 2014), where I do research in Computer Architecture with Prof. Yale Patt at the HPS research group.

My research interests are related to computer architecture and the interaction between HW and SW. I'm a full stack research engineer with experience ranging from application development and OS kernel development to microarchitecture simulation. Prior to UT, I worked as an intern at Intel (Summer 2012) and as a Researcher at the Barcelona Supercomputing Center (2005-2011) where I got my Phd in the UPC Computer Architecture Department (2005-2012). From 2005 to 2011, I was a Lecturer at UPC and at La Salle School of Engineering (2000-2002) teaching Computer Engineering undergraduate courses.

I got my B.S. degree and M.S in Computer Engineering at La Salle School of Engineering (1994-2000).

I have also experience as an entrepreneur. In 2000 I co-founded a consulting firm Cometa Technologies (200-2002), later acquired by Smile Group in 2009. I have also mentored several graduate and undergraduate students on research and startups.
