I am a staff research engineer at together.ai. I am a systems generalist with expertise in hardware-software codesign, distributed systems, storage systems, and operating systems. Nowadays, my work is mostly co-designing optimizations across the inference stack, with a focus on the kernel-engine interface.
Previously, I was a senior software engineer at Google in the systems research group and before that a researcher at VMware Research.
For an up-to-date list of my publications, please refer to my Google Scholar profile.
