B.S. Biology 1999 - Hope College, Holland Michigan


I was born and raised in West Michigan and went to Hope College for my undergraduate degree. After college I went to Maryland for an internship at The Salisbury Zoo. After that, I stayed in the state and initially worked as a lab technician for a biotech company in Rockville, MD (BioReliance) performing immunoassays (ELIZA, IFA, Western Blot). I then moved to Maryland's Eastern Shore and worked for 6 years as a hatchery technician at an oyster aquaculture business on the Chesapeake Bay. One of my responsibilities was growing microalgae as a food source for brood-stock and larval oysters. In 2011, I returned to Michigan to get my Masters Degree in biology with an emphasis in aquatic science from GVSU. For my thesis, I am working on the Muskegon Lake Observatory Buoy project in the lab of Dr. Bopi Biddanda. I am using high-frequency time-series buoy data to study seasonal and episodic drivers of phytoplankton productivity along with other lake processes. In particular, I am looking at how the lake responds to inter-annual variability of climate and weather patterns.
