I am a Research Scientist at Facebook.
I was a PhD candidate (ABD status, having completed all requirements but my dissertation) in Electrical and Computer Engineering at Carnegie Mellon University in Pittsburgh Pennsylvania, where I was advised by Onur Mutlu. I was named a Google PhD Fellow in 2015 as well as a John and Claire Bertucci Graduate Fellow in 2013. My research focused on designing reliable, high-performance, and energy-efficient memory architectures.
I received my BS at the University of California at Los Angeles in Computer Science in 2010 and my MS at Carnegie Mellon University in Electrical and Computer Engineering in 2014. I interned at Google during the summer of 2014, where I worked with Partha Ranganathan, Jichuan Chang, Kim Hazelwood, Joel Coburn, and Rama Govindaraju. I interned at Facebook from 2013 to 2014, where I worked with Qiang Wu and Sanjeev Kumar, and again from the fall of 2014, where I worked with Qiang Wu and Yee Jiun Song. I also 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.

Sometimes, when I work at a company, I submit patent applications for my inventions. Below is a list of the patents for which I am an inventor.
I work on a variety of open- and closed-sourced projects (the open source projects I contribute to can be found on my GitHub). Below is a selection of the projects I contribute to.
LOLCODE — I wrote and maintain the most widely-used interpreter for the LOLCODE esoteric programming langugage. I now maintain the LOLCODE specification as well as its website.
inet — inet is a simple TCP/UDP communication library written in C. It abstracts away the icky socket and protocal interfaces into a more declarative host-based model of communication.
triad — triad is an implementation of the Chord peer-to-peer lookup service in C. It maps 64b integers to IP addresses and can be used as the underlying service-discovery layer for a distributed system.
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 traveling around, working toward completing my PhD at CMU. My Chinese name is 梅杰士.
I’m an avid music fan and when I have free time, I enjoy playing the electric bass guitar and keyboard. I also enjoy art (mainly 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:
