Professional Interests

Mark is broadly interested in aquatic microorganisms' role in biogeochemical cycles. While at DRI, his specific focus was investigating nitrogen and phosphorus dynamics on a watershed scale, and examining microbial exoenzyme activities as indicators of nutrient imbalances within microorganisms.

Current Research

Under Dr. Fritsen's advisement, Mark's research addressed nutrient limitation of periphyton growth in the Truckee River (California-Nevada). The Truckee River begins at its outflow from Lake Tahoe, and ends where it enters Pyramid Lake. Previous investigations have shown that Lake Tahoe phytoplankton growth is generally phosphorus limited, and Pyramid Lake phytoplankton growth is consistently nitrogen limited. Mark hoped to show that periphyton growth in the Truckee River changes from P to N limited along its continuum, and locate where that transition occurs.
