Justin Meza (梅杰士)

I am a John and Claire Bertucci Graduate Fellow at Carnegie Mellon University in Pittsburgh, Pennsylvania pursuing a PhD in Electrical and Computer Engineering, where I am advised by Onur Mutlu. I am interested in designing reliable, high-performance, and energy-efficient memory architectures.

I recently interned at Facebook, where I worked with Qiang Wu. I received my BS at the University of California at Los Angeles in Computer Science in 2010 and I interned at Hewlett-Packard Labs in Palo Alto, California from 2006 to 2012, under the guidance of Rich Friedrich, Partha Ranganathan, Mehul Shah, and Jichuan Chang.

I recently taught a guest lecture on memory scheduling policies in CMU's Introduction to Computer Architecture course, 18-447. — More on teaching

Publications

I currently research reliable, high-performance, and energy-efficient memory architectures in Onur Mutlu's SAFARI group at CMU.

Patents

Sometimes, when I work at a company, I submit patent applications for my inventions. Below is a list of the pending patents for which I am an inventor.

Teaching

At CMU, I help lecture, administer course material, design homework assignments, and design lab assignments, for computer architecture courses. Below are some examples of lectures and recitation sessions I have given.

Personal

My full name is Justin James Meza (my last name is pronounced "meɪzʌ" in IPA) and I'm of Caucasian and Mexican descent. I grew up near Los Angeles, California, although I'm currently in Pittsburgh, Pennsylvania working toward my PhD at CMU.

These days, I spend all of my time performing research. I’m an avid music fan and when I used to have free time, I enjoyed playing the electric bass guitar and keyboard. I also enjoy art (oil paints and gouache!), reading, writing, and, of course, programming :). I run on Verve and Philz coffee. I have a personal blog, but I only rarely post on it.

These are some generally useful books that I like to keep within arm's reach:

  • The Bedford Handbook
  • The Elements of Style
  • BUGS in Writing
  • The Visual Display of Quantitative Information
  • Presentation Zen
  • Getting Things Done
  • Take Back Your Life!
  • Leadership is an Art
  • Serious Creativity

The love of my life, Jamie Batrez, studies character animation at the prestigious California Institute of the Arts; check out some of her amazing work!
