Dr. Clark completed his Ph.D. work at Rensselaer Polytechnic Institute in Troy, New York. He has 30 years of experience in designing and conducting testwork and research programs, including 15 years related directly to minerals related microbial processes. He developed and co-taught an industrial short course for microbiology of biooxidation and bioleaching of mineral sulfides and acid mine drainage.

From 1996 to 2007 (11 years), he was Senior Scientist with the innovative Little Bear Laboratories, investigating novel approaches to metal sulfide biooxidation and control of acid mine drainage.

Two years as Senior Scientist and then Director of R&D at GeoSynFuels expanded his process range to biofuel production.

From December 2008 – 2012 (four years), he was Director of Research and Development for GeoBiotics, Inc., designing and coordinating test programs for refractory precious metal bearing sulfide concentrates, as well as base metals ores and concentrates in Chile, Brazil, and South Africa.

Dr. Clark is accustomed to working at lab bench scale, pilot scale and in the field at demonstration plant scale.
His goal has always been to provide unbiased and high quality data to assist in decision making and contribute to design, while innovatively applying basic scientific principles from multiple fields of study to biologically based process development.

Published co-author in areas:

  • Biooxidation / bioleaching (ores and concentrates)
  • Acid mine drainage control
  • Coal depyritization (sulfide oxidation)
