Principal Investigator

Joy O’Keefe (She/Her)

Joy O’Keefe grew up in Raleigh, North Carolina, the land of vinegar style BBQ and sweet tea, but always wanted to be from the Midwest, so it has worked out well that this has become her academic home. From a young age, Joy was passionate about conserving animals – first the voles the cat brought to the back door, then tigers were a passion, and finally bats captured her heart. She completed her B.S. in Zoology from North Carolina State University, with an undergraduate thesis on behavior of Coquerel’s sifakas. Then she moved to Kentucky to do her M.S. in Biology, studying Ruffed Grouse at Eastern Kentucky University. She headed south again to complete her Ph.D. in Wildlife Ecology at Clemson University studying the ecology of forest-dwelling bats in western North Carolina. Joy has since led many large-scale projects studying bat ecology in the southern Appalachian Mountains and the Midwest. Understanding bat responses to forest management has been a major focus of her work, but she is also keen on other types of conservation-oriented work for the threatened and endangered bats of eastern North America. jmokeefe at

Master’s Students

Josie Hoppenworth (She/Her)

Josie Hoppenworth is from DeKalb, Illinois, home of the DeKalb Barbs (their mascot is a crow… obviously). She received her Bachelor’s degree in 2023 from the University of Illinois Urbana-Champaign where she studied civil and environmental engineering. While she pursued a degree in engineering, she has always had a passion for the environment. Following a study abroad trip to Tanzania in December 2022, she became determined to work with mammals for the purpose of wildlife conservation. She is now pursuing a Master’s degree in the department of Natural Resources and Environmental Sciences under Dr. Joy O’Keefe. Her thesis focuses on the factors affecting the longevity of historical tree roosts used by the Northern long-eared bat and Indiana bat in southern Indiana. The results of this study will help scientists understand the persistence of tree roosts on the landscape and provide guidance for forest management practices. jch8 at

Johnny Baakliny (He/Him)

Johnny Baakliny is an Architect turned Wildlife Conservationist. He grew up in Lebanon surrounded by pine forests and mountainous terrains of a highly biodiverse region of the Mediterranean, which sparked his early passion for the natural environment and concerns for conservation. Johnny is a passionate researcher, field herper, and wildlife photographer with a deep appreciation for the beauty and diversity of amphibians and reptiles. He is currently completing his Master’s of Landscape Architecture (MLA) with a cross-disciplinary focus on the relationship between humans and wildlife. His Master’s research examines management practices and public attitudes towards snakes in Southern Illinois, and the impacts of “Snake Road,” a distinct landscape with exceptional biodiversity that draws a large public, bringing them into close proximity with venomous snakes, namely Cottonmouths. Johnny also shares a deep passion for bat conservation and has worked as a Bat Field-Technician on several projects and currently assists Professor O’Keefe in her public education and outreach work at the Illinois Extension. Johnny believes in bridging ecological research and socio-political concerns to better inform conservation practices and influence public attitudes and perceptions towards wildlife. johnnyb2 at

Nicole Dobrosky (She/Her)

Nicole Dobrosky is from Easton, Pennsylvania, city of hoagies and home to Crayola crayons. Her lifelong interest in wildlife conservation led her to earn a BA in Animal Behavior in 2020 from Franklin & Marshall College in Lancaster, PA. She studied abroad in Kenya and has assisted in researching capuchin monkeys at F&M, flying squirrels in Tennessee, sage grouse in Idaho, and wild turkeys and black rails in Florida. Her undergraduate honors thesis examined urban bat ecology in Lancaster, and she is excited to return to studying bats for her Master’s thesis. Her research focuses on estimating population density of Indiana bats (Myotis sodalis) utilizing acoustic monitoring. She is particularly interested in anthropogenic impact on wildlife populations and how this research might be applied to forest management decisions. ncd5 at

Doctoral Students

Katie Fitzgerald (She/Her)

Katie Fitzgerald grew up in sunny San Diego. She earned her bachelor of science degree in Natural Resource Management and Conservation from San Francisco State University. After taking a field course on the ecology of bats, she was officially hooked. This interest led to working with various agencies, such as National Park Service and U.S. Fish and Wildlife Service. She had the opportunity to assist in bat research in southern Mexico, Borneo, and Madagascar. She completed her Master’s degree at Angelo State University in San Angelo, Texas. Her Master’s work characterized seasonal variation of the diet of cave myotis (Myotis velifer) found in a historic fort in Presidio, Texas. Katie’s Ph.D. research will focus on monitoring the health of Indiana bats (Myotis sodalis) to determine whether forest management practices affect populations. Managed sites that are effective may provide bats with various roosting habitats and minimize competition with conspecifics. In addition to connecting to nature through science, Katie enjoys backpacking and is a novice rock climber. kvf2 at

Reed Crawford (He/Him)

Reed Crawford is originally from the small town of Riley in west-central Indiana. He completed his Bachelor’s in biology in 2018 at Indiana State University, during which he worked on several Indiana bat (Myotis sodalis) related projects in central and southern Indiana. In 2020, he completed his Master’s at Eastern Kentucky University, studying Indiana bats and artificial roost usage in northern Kentucky and central Indiana. Reed’s PhD research focuses on the thermoregulatory strategies used by Indiana bats in both artificial and natural roosts. Additionally, he is building a variety of rocket box style bat houses for future work. Reed is also interested in roost selection and studying ecological traps. reeddc2 at

Postdoctoral Researchers

Elizabeth Beilke (She/Her)

Lizz Beilke originates from Wisconsin, the land of beer, cheese, beer cheese, and other yellow foods. She earned her bachelor of science in ecology and environmental biology from the University of Wisconsin-Eau Claire. There, her research focused on behavioral mechanisms of isolation in Bahamian pupfish and pedagogy in conservation biology. After graduating, she spent a few years working for USGS in North and South Dakota and then USFWS in Mississippi. After having studied assorted fish, bird, and insect species, she settled on bats for her Ph.D. Lizz is interested in a variety of ecological topics, but her thoughts are currently occupied by resource partitioning, foraging ecology, and trophic cascades. Her dissertation is focused on the ways different bat species share resources (time, space, and prey) and how bats affect the ecosystems they are a part of. She is also studying the diet, foraging ecology, and sexually-dichromatic fur color of the best bat, the Eastern red bat. ebeilke at

Andrew Bennett (He/Him)

Texas born but raised in the northeastern United States, Andrew Bennett has worked at the intersection of human and animal health for more than a decade. He studied ecology and evolutionary biology at Cornell University, where he received his BS, and went on to earn a PhD in Comparative Biomedical Sciences at the University of Wisconsin-Madison. For his dissertation he studied Ugandan bats and their ectoparasites–and the viruses they host–with the goal of better understanding what makes bats special in their capacity to host high-consequence pathogens. For his postdoc, he will develop field and laboratory methods to assess bat health in order to help inform management strategies and to further elucidate what makes bats special. andyb at
