Chief Engineer                                                                                                 2003 – present

Diluvian Technologies, LLC, Galveston, TX                                               

   Performed all mechanical, electrical, software (QBasic, registry level) engineering and design (video of the system in operation is available)

   Integrates automated solution changes with automated drying, and eliminates the production of volatile fixative fumes with continuous sample coverage


Cytogenetic Technician (2 years)

Laboratories for Genetic Services, Houston, TX

Fabricated sample covers to minimize the production of volatile fixative fumes and fine-tuned the software for precise positioning of dispensing and aspirating

Performed the system validation tests

   This experimental apparatus eliminated the variability of harvest quality between technicians and improved overall harvest quality and consistency.  It also cut the technician time devoted to harvesting by over one half.
