About me

I am a geophysicist residing in Houston, TX. I'm currently a seismic processing geophysicist at DownUnder GeoSolutions. Seismic processing is a recent career change—quite recently I was still focused on earthquakes and crustal deformation. Prior to my current role at DUG, I worked for Chevron Energy Technology Company in the R&D division, which was in a way my bridge from academic geophysics to industry. I was originally hired to work on integration of geomechanics and geophysics, with emphasis on subsurface hazards, but those ambitions turned out to be unviable after the oil price collapse.

Before joining the energy industry, I completed a Ph. D. at Stanford University Geophysics Department in the Crustal Deformation and Fault Mechanics group. My research there examined the frictional behavior of faults as slip nucleates and transitions into seismic rupture. To that end, I developed numerical models that couple elasticity and frictional sliding to shear heating and diffusion of heat and pore pressure.

For my MS at the University of Wisconsin, I used GPS data to study the 2003 Tecomán, Mexico earthquake.

Publications and presentations


Public presentations are listed on a separate page.


FreeUSP website mirror—FreeUSP is a Unix-based seismic processing toolkit that was developed at Amoco and then BP. As of September 2022, BP has decommissioned the FreeUSP website. This is a mirror of as much of it as I could find. I had archived the man pages myself years ago; the rest is thanks to the Internet Archive.

General Motors Entertainment and Comfort serial bus—This page presents information that I have learned as part of an ongoing project to reverse-engineer one of the serial busses found in one of my cars.

Using linear flash PCMCIA cards on modern desktop computers—It is possible with Linux.

OTC Genisys OBD-I DB-25 to DIN-8 cable—You can make your own.

Battery replacement for Triplett 631 vacuum tube voltmeter—This multimeter/VTVM was originally powered by two 22.5 V batteries that are no longer available. I designed a method to power it with an array of 30 AAAA batteries.

Apple MagSafe DC auto/airline adapter—I have developed a solution for powering an Apple MacBook or MacBook Pro from a 12 VDC car cigar lighter or a 15 VDC airline in-seat EmPower connector. Parts cost less than $100 and some soldering is required.

Automotive information—I am somewhat of an automotive enthusiast; I occasionally post something car-related on my web page. Lately, I have not had much time to update this information, so it mostly reflects cars I do not have anymore.
