I am a life-long angler from Cambridge City, Indiana. Some of my earliest memories are fishing local ponds or exploring streams near my home. This interest led me to pursue degrees in fisheries management. After receiving my BS and MS at Ball State University, I started my professional career as a seasonal fisheries technician for the Indiana Department of Natural Resources (IDNR) in May 2003. This position led to a full time position as an assistant fisheries biologist for IDNR. In 2006, I returned to Ball State University as a Research Biologist to lead their long-term monitoring of Yellow Perch in Southern Lake Michigan. At this position, I started to become exposed to modeling and found out how enjoyable it could be. After a few years, I switched from big lakes to small streams as the Fisheries Biologist for the Bureau of Water Quality in Muncie, Indiana. At this position, I was responsible for monitoring the fish community and habitat in wadeable streams to assess biological integrity and habitat quality. It was at this position when I started learning about Bayesian inference. I quickly realized this method of inference was extremely exciting. In 2012, I started a doctoral program at Ball State University. While pursuing my PhD, I found out I wanted to combine my research interest in quantitative fisheries management with teaching. After finishing my doctoral program in 2015, I accepted a contract faculty position with Ball State University to teach introductory Biology, introductory statistics for Biology students, and a graduate course on statistical modeling in Ecology.
My research interests are in quantitative fisheries ecology. Broadly, I am interested in evaluating the mechanisms that influence fisheries populations and communities; including human disturbance (e.g., harvest, pollution, and habitat degradation), macroecological mechanisms, and the numerous biotic and abiotic interactions between fish and the environment. I am particularly interested in discovering these interactions using Bayesian inference of complex models. To accomplish this, I employ a multifaceted approach to data collection using historical data, field collection of new data, and collaboration with other scientists. Although I typically study fish population and community dynamics from field or laboratory research, I have collaborated on projects studying a variety of other taxa (e.g., ungulates, primates, warblers, bats, spiders, and algae) and environmental contaminants (e.g., environmental pharmaceuticals and personal care products and pesticides).
My research has included a wide range of projects from evaluating statistical methods of estimating parameters of common fisheries models to investigating continental wide distributional patterns of fish and evaluating physiological patterns of swimming performance. For example, I have compared Bayesian and frequentist methods of estimating fish mortality from catch curves and evaluated the efficacy of Bayesian inference of age and length at 50% maturity of fish. Through a grant from the Indiana Department of Natural Resources, I used historical data from their fisheries information system to evaluate stock-recruitment and yield-per-recruit models of Walleye Sander vitreus and Moronidae sp. (both stocked species). My research has also involved population modeling of the near-shore fish community of Lake Michigan with an emphasis on Yellow Perch Perca flavescens population dynamics and prey fish dynamics in Lake Huron. I have also investigated stream health using biological and habitat indicators. My current research project is a length based integrated stock assessment model of prey fish in Lake Huron that will help agencies manage the Lake Huron fishery.
