Hello! I’m Joel and this my personal website built with Jekyll! I currently
work at Nvidia. My interests are scheduler, RCU, tracing, synchronization,
memory models and other kernel internals. I also love contributing to the
upstream Linux kernel and other open source projects. In prior jobs, I worked
at Google, Amazon and TI.
Connect with me on Twitter, and
LinkedIn. Or, drop me an email at:

Look for my name in the kernel git log to find my upstream kernel patches.
Check out my resume for full details of my work
experience. I also actively present at conferences, see a list of my past
talks, presentations and publications.
