Jonathan began his science career as a laboratory analyst in an environmental compliance laboratory focusing on public use of over 70 drinking water systems, several wastewater systems and irrigation projects in Monterey County, California. Other projects have included state contracts for the California State Parks, Oil and Grease analysis for the Monterey Bay Aquarium, and ion and metal analysis for NASA. While there, he was given experience and formal instruction on equipment including: an Ion Chromatograph (IC), an Inductively Coupled Plasma Mass Spectrometer (ICP-MS), an Inductively Coupled Plasma Optical Emission Spectrometer (ICP-OES), and an Atomic Absorption Spectrometer (Flame AA). In addition to instrumental analysis, he learned several wet chemistry and microbiological procedures taken from Standard Methods and other EPA approved sources. In addition to his role as Hatchery Program Manager, Jonathan is currently a Research Specialist at the University of Connecticut.
