Student Maria J. Kommeth sets the lens for the laser as professor Jeannette Yen looks at it. This is research about microorganisms in the Biology Department. Focused on the study of aquatic chemical ecology, Dr. Jeannette Yen’s lab employs graduate and undergraduate students alike to understand marine zooplankton interaction, behavior, morphology, ecology, and reproductive strategies. Current research topics range from studying harmful algal blooms’ effect on marine copepod behavior to understanding swimming behavior and hydrodynamics.
