January 1999 - May 2005
Study of Geophysics at a graduate level; Research Assistant

* Research hydrocarbon fluid properties under different, especially
  reservoir conditions at the CSM Center for Rock Physics. Practical
  measurements and theoretical analysis and interpretation.
  Developed own data processing system, data format and plotting
  library for analysis.

* Study of geophysics with special regards to numerics, modeling and
  mathematic programs like Mathematica or Matlab.

* Co-designed the future direction of the computational education in
  the department. Publication.

* Expanding and modernizing the COOOL C++ optimization library.

* Maintaining the Common Ground Database of rock and mineral
  properties. Develop and maintain a custom public web interface.

  groups.

Landmark Graphics Corporation                                Denver, CO
Summer 2000 and Summer and Fall 2001
Internship as Tester/Developer

* Testing of the ProMAX data processing package for the 1998.6
  release.

* Wrote an automated testing framework for ProMAX in Perl and Lisp.

Freiberg University of Technology                     Freiberg, Germany
September 1996 - January 1999
Study of Geophysics at an undergraduate level; Research Assistant

* Scientific programmer for a sensor to measure groundwater flow.
  Real-time controlling of the sensor via RS232, data acquisition,
  processing, and visualization. The programming was in Turbo Pascal
  and Assembler on MS-DOS at both the application and system
  programming levels.

* Modeling the distribution of electromagnetic properties in the
  earth. Provided a visual interface to load and save different
  model types, view models, and change properties. The programming
  was done in Unix/C++. For the visual interface I used
  X-Windows/QT.

These jobs funded my educational and living expenses.
