Projects:
-NASA QuakeSim and E-DECIDER projects, Dept. of Energy (DOE) Damage and fracture research.
-Virtual Quake/California Earthquake simulator (VQ):
- GitHub: https://github.com/geodynamics/vq
- Simulator development (C++, Python, MPI)
- Data mining
- Python/C++ extension based data mining toolkit development
- Synpsis: VQ is a boundary element, fault type earthquake simulator. The primary benefits of the simulator are that we can 1) produce extended, ~10,000 + year, earthquake catalogs from which we can directly calculate the statistics of large earthquakes, 2) sort and partition the data to isolate individual rupture sources, and 3) modify the physics and fault geometry in order to conduct specialized experiments. My roles in the project include incorporating the correct physics into the simulator, the development of production-grade code for both the simulator and analytical tools, designing experiments with the simulator and analyses of the data, publishing papers, and overseeing development activities.
- Data modeling, numerical simulations:
- Model validation and verification
- Physical and statistical model constraints
- Seismic hazard analytics, statistical models of earthquakes, seismicity sequences, fracture mechanism, and other advanced scientific statistical methods.
- “Invasion percolation” based damage propagation model related to hydro-fracturing, earthquake rupture, and wildfire propagation.
- Short, medium, and long term earthquake forecasting.

Relevant skill-set:
Data intensive Python and C++ development, Oracle and SQL, advanced database technologies including Cassandra. From February 2014 to July 2014 (6 months) Lecturer/Instructor @ Teaching GEL-17, "Earthquakes and other Hazards," a review type course discussing natural hazards, hazard engineering, and the makings of a "disaster" from hazard:
The cost, in both lives and property, incurred from natural disasters is a direct threat to sustainability. Some examples: Combined, the 2004 Sumatra earthquake and tsunami and the 2010 Haiti earthquake resulted in over 500,000 deaths and many billions of dollars in damage. The 2008 Wenshuan earthquake in China killed over 70,000 people and completely destroyed several towns in the mountainous region; Hurricane Katrina (2005) resulted in over $108 billion in damages, and the 1900 hurricane in Galveston killed over 8,000 people. While we cannot stop earthquakes, volcanoes, and hurricanes, by understanding these natural hazards -- even on a very basic level, we can significantly mitigate losses and save lives. This course strives to develop a basic literacy of the physics and Earth science behind these various natural hazard and also discusses means by which exposure to them can be mitigated. From September 2013 to February 2014 (6 months) Instructor of Physics @ Taught introductory physics to, primarily, nursing, industrial arts, and biological science majors. The primary objective of the course was to develop strong critical thinking and problem solving skills, as opposed to simply plugging numbers into equations. An additional objective was for students to develop confidence in the face of unfamiliar challenges, for example to understand that equations are not (always) scary; rather they are a compact way of presenting certain types of information. From September 2012 to December 2012 (4 months) Graduate Research and Teaching Assistant @ Statistical physics and natural hazards science: wildfire dynamics, seismic hazard, operational earthquake forecasting. From September 2005 to December 2011 (6 years 4 months) Software Developer/Systems Analyst @ Summary: Industry software development is driven by customer demand. Customers demand products that work dependably, are easy to use, and that save them time and money. Software development involves a pipe-line that starts with proof of concept and terminates with extensive QA testing and an *on time* release into production. Data driven, web (or mobile) based products are often built on top of a complex back end infrastructure; it is critical for a good developer to consider not only the project at hand, but the versatility and scalability of this infrastructure to efficiently support new products in the future.

From November 1996 to September 1997 (11 months) Snowboard instructor @ "Your snowboard doesn't care what you think or what you want; your snowboard only obeys the laws of Physics. Fortunately, the laws of physics are very predictable. On the other hand, they are quite unforgiving."
When possible, I liked to teach little lessons in Physics in the context of snowboarding. One of my principal strategies was to break the sport down into its very fundamental components -- in other words, find the simplicity in this very complex sport.
