Experience

GX Technology, AXIS Imaging Division May 2005 - present Denver, Colorado
Research & Development Geophysicist
  • Develop custom seismic data processing modules for velocity analysis and anisotropic processing.
  • Maintain and refactor the AXIS P-wave anisotropic codes. Develop a testsuite for processing QC.
  • Reverse engineer large parts of the ProMAX system and develop an automation framework.
 
Colorado School of Mines January 1999 - May 2005 Golden, Colorado
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.
  • Development of cross-platform, user-friendly educational GIS software.
  • Education and supervision of fellow research assistants.
  • Working in the Linux Users Group of the Colorado School of Mines to introduce Linux and help with installation problems.
  • System administrator, computer security educator and webmaster for the Physical Acoustics Lab, the Rock Physics Lab and other working groups.
 
Landmarks Graphics Corporation Summer 2000 and 2001 Denver, Colorado
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 September 1996 - January 1999 Freiberg, Germany
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.
