HPC Performance Analyst

Materials Scientist

I am a computational scientist and specialist in high-performance computing systems currently working at the National Energy Research Scientific Computing Center (NERSC) at Lawrence Berkeley National Laboratory. My work focuses on I/O performance analysis, extreme-scale storage architectures, and emerging I/O technologies and interfaces.

In my previous life, I did research in computational materials science and studied the chemical physics of water/silica interfaces with molecular dynamics simulation. I also spent some time working in the DNA sequencing industry helping to connect bioinformaticians with the computational resources their work demanded. More information about me is available on my CV and on LinkedIn.

This site contains various notes I've taken related to technical computing over the years. I welcome any feedback about its contents at the e-mail address listed at the bottom of every page, and I can also be found in #hpc on freenode.

Data-Intensive Computing

My career has largely revolved around data-intensive scientific computing. Most of my current work is in storage systems and architecture, but in the past I have worked in the application space with tools including Hadoop and R.

HPC Howtos

In the past I have worked as both a user services consultant and a systems enginer. This section contains a few notes relevant to using and managing HPC resources, but the bulk of my HPC how-to guides remains hosted at the San Diego Supercomputer Center.

Performance & Benchmarks

This section contains a number of disjoint pieces revolving around performance analysis.

Materials Science

When I was a student I maintained a variety of notes about different topics relevant to ceramic engineering, in which I got my undergraduate degree. I've re-uploaded them here for posterity.


I've created the following pages about my hobbies mostly for my own entertainment. They have little to do with what I do professionally, but they might be of interest to people who hold similar interests.
