My research interests focus on studies intended to inform the assessment and management of fishery resources. Most of my projects are field-based surveys or tagging studies aimed at investigating fish population structure, seasonal movements, discard mortality, or spawning dynamics. I enjoy working on a variety of projects with a diversity of collaborators from academic, state, federal, and non-profit institutions, in order to provide scientific advice that promotes the sustainability of marine fisheries and fishing industries that depend on marine resources. I particularly enjoy working collaboratively with recreational and commercial fishermen by including them as part of research teams and incorporating their knowledge, skills, and expertise into scientific research.
I was born and raised in Edison, NJ near the New Brunswick campus of Rutgers University. I received a B.S. in Marine Sciences from Rutgers University (2005–2009) and then completed a Ph.D. in Marine Science and Technology at the School for Marine Science and Technology (SMAST), University of Massachusetts Dartmouth (2009–2016).
