Josh was introduced to aquatic and evolutionary biology while earning his B.S. and M.S. in Ecology and Field Biology from St. Cloud State University, St. Cloud, MN. From there he earned his Ph.D. from the University of Colorado Boulder in Ecology and Evolutionary Biology where he utilized molecular and comparative phylogenetic techniques to examine evolutionary patterns in oil accumulation within an important group of microscopic algae.
After graduate school, Josh joined the research faculty at St. Cloud State University where he oversaw operation of the campus Bioenergy and Biomass Sustainable Energy Facility, which included an anaerobic digestion system and 16,000 liter capacity algal growth system.
His current research interests continue to lie at the intersection of evolution, ecology and applied phycology. These include studies in algal taxonomy and systematics, the pattern and timing of ecological shifts within algal lineages and the phylogenetic, physical and biochemical characterization of commercially important algal groups.
Josh is currently an Associate Professor of Biology at Colorado Mountain College Vail Valley where, outside of teaching and research, he spends his time fully taking advantage of the beautiful Colorado mountain landscape in all its forms.
