Dr. Jeffrey A. Stein,
Senior Research Scientist

My research interests focus on the study of basic and applied ecology of freshwater and marine fisheries to understand linkages between ecological function and exploitation of populations by human activities. Fundamentally, I seek to explore how human activities can impact the reproductive ecology and behavior of fishes, ultimately translating findings into meaningful and effective conservation actions.

Dr. David Philipp's research interests focus on three major areas: conservation genetics, reproductive ecology, and the effects of fishing on natural populations. His findings have helped to document the negative impacts of outbreeding depression that can result from hatchery stocking programs, as well as to illustrate the evolutionary effects that fishing can have on natural populations. Much of his research has targeted centrarchid species, particularly focusing on the factors that impact their parental care activities, reproductive success, and annual recruitment. In recent years, Dr. Philipp has broadened his interest in these research topics to include the marine flats ecosystem, studying bonefish reproductive behaviors and the effects of recreational angling on post-release behavior and survival of flats fishes.

Dr. Philipp teamed with Orvis on a short video clip about how bass move with the seasons. View that clip here.



Julie E. Claussen, Research Scientist

I began working at the Natural History Survey in 1984, and after a short stint working on stream ecology projects, I joined the fish genetics laboratory working on the conservation of native fish populations. Over the years, my interests in fish and fisheries research have evolved to include the reproductive life history of centrachids, sustainable fisheries practices and management, and the impact humans have on sport fish populations. Many of the studies I am involved with focus on the effects of recreational fishing, including its impact on reproductive activities, reproductive success, recruitment, post-release behavior and survival. Another large area of focus is the long-term effect of fisheries management stocking practices and outbreeding depression in fish populations. In more recent years, I have worked on new methods for fisheries outreach and education, recognizing the need for scientist to engage with the natural resource constituents.

Josh Sherwood,
Fisheries Researcher

My research interest is primarily in stream ecology. I received my Bachelor's Degree in Natural Resources and Environmental Sciences from the University of Illinois in Urbana-Champaign in 2009, focusing on Fish and Wildlife Conservation. While an undergraduate, I worked as a Field Technician at the Illinois Natural History Survey where I conducted fish and mussel surveys across Illinois. I received my Master's Degree from Western Illinois University in 2011. While working toward my Master's, the focus of my research was performing freshwater mussel surveys of the Spoon and La Moine Rivers and examining the effects of basin land-use on mussel communities. I am happy to be back at the University of Illinois as a Research Scientist at the INHS working on the Fishes of Champaign County project.



Kristen Patterson, Fisheries Researcher

My research interests largely lie in factors affecting the success of native fishes. I received my Bachelor’s Degree in Marine and Freshwater Biology from the University of Guelph in 2007. During that time, I gained a range of experience in everything from fisheries assessments of the lake-wide community in Algonquin Provincial Park in Ontario to the experimental rearing of cod families for aquaculture on the east coast of Canada. I obtained my Master’s Degree from the University of Manitoba in 2011, where the focus of my thesis was determining the potential impacts of farmed rainbow trout that escape from cage culture operations in Lake Huron. I spent two and a half years post-graduation in Arizona monitoring populations and determining factors limiting the survival of endangered fish species in the desert southwest. I am excited to be back in the Great Lakes region and look forward to contributing to sport fish restoration as a Research Scientist with INHS.



Dr. James Lukey, Post-Doctoral Researcher

My research interests focus on three areas: fish ecology, conservation biology and conservation decision-making. I received my Master of Science in Marine Biology from Rhodes University in South Africa in 2006. My work focused on fish communities in a small intermittently open estuary and examined the movement and habitat use of different species in these important nursery habitats. In 2006, I worked on a project identifying important marine priority habitats and species for the National Biodiversity Action Plan for the Marine Biological Association of the UK. I earned my Doctor of Philosophy in Zoology from the University of Guelph in 2010, examining decision-making of species at risk. I worked as a Post Doc at the University of Notre Dame focusing on the impacts of climate change on species ranges and the integration of effects of climate change on species at risk. At the Illinois Natural History Survey, I am examining the sport fish community in the recently restored West Branch of the DuPage River. This work includes examining communities of fish in the urban stream environment and telemetry work on adult smallmouth bass, reviewing their movements and habitat use.

Each field season, our lab provides internships to undergraduate students to gain valuable experience in fisheries field ecology. Through our collaboration with the Illinois Department of Natural Resources Division of Fisheries, we place students side by side with professional fisheries managers to assist with extensive field sampling of fish populations throughout Illinois. Our interns gain valuable, real-world experience in fisheries ecology and are an important part of many of the fisheries research and management activities throughout the state of Illinois.
