Boyce Research

Richard Boyce

Office: SC 150 | Phone: (859) 572-1407
E-mail: boycer@nku.edu

A main area of Dr. Boyce's research centers around the effects of invasive woody plants, especially Amur honeysuckle. He's been examining how native plant communities recover after honeysuckle has been removed. He is also looking at how honeysuckle is responding to outbreaks of a native pathogen, honeysuckle leaf blight. Recently, Dr. Boyce extended his work to a recent invader, Callery (Bradford) pears, which has moved from yards to the wild. Another area of research centers around photosynthesis and water use by eastern red cedar, our only native evergreen tree. Measurements of chlorophyll fluorescence and sap flow show that carbon uptake is substantial outside of the growing season, which may explain why it can thrive in our region.

Carlson

Brian Carlson

Office: SC 352| (859) 572-7997
E-mail: carlsonb2@nku.edu

The idea of being able to simply observe an organism and know something about its genome or, conversely, to look at genotypic data and know something about how an organism looks, functions or behaves has fascinated Dr. Carlson since his first exposure to the principles of genetics, and has served as one of his primary motivators as he has pursued research projects. Along the way, he has also developed an interest not only in identifying the genetic underpinnings of phenotypes, but in helping to develop the tools and resources that enable us to ask these questions in the first place. Dr. Carlson is also a strong believer in the power of collaboration, and enjoys using his skill set to assist others in answering questions of interest to them. His current research is focused on exploring the genetic basis of morphological and behavioral phenotypes in non-model fish species.

Dahlem

Greg Dahlem

Office: SC 248 / (859) 572-5733
E-mail: dahlem@nku.edu

Dr. Dahlem's rresearch involves the discovery of new structural features of flesh flies to allow species level identifications of New World flesh flies and blow flies (Sarcophagidae & Calliphoridae) by morphological features. He has been exploring the use of stacked digital photography and 3-D scanning to render high quality photos or (potentially) 3-D models of key morphological features to help non-specialists accurately identify specimens of these flies. He provides identifications for researchers in other disciplines. For example, he is currently working to identify a group of flies reared as predators of turtle egg clutches in Wisconsin. Dr. Dahlem also provide identifications and information on flesh flies reared from human corpses at crime scenes for crime labs around the United States. He writes a column on new and interesting entomological research for the magazine American Entomologist, and has given numerous forensic entomology demonstrations for school groups, libraries, and museums.

Alllison Parker

Allison Parker

Office: SC 254 | (859) 572-6674
E-mail: parkera10@nku.edu

Dr. Parker is an eco-epidemiologist, which means she studies the intersection between ecology and disease. Her research focuses on mosquitoes and the diseases they transmit in human-dominated landscapes. Since we do not have vaccines for many of the viruses spread by mosquitoes, controlling mosquito populations is the best way to prevent diseases transmission. She looks at how mosquito species distribution and abundance varies based on how humans have altered the environment and how humans knowledge, attitudes, and mosquito control practices affect potential for mosquito-borne diseases to spread. Dr. Parker then uses this information to create outreach tools to work to reduce mosquito populations. Her research allows her to work with her community partners and the public.

Robertson

Denice Robertson

Office: SC 245 | (859) 572-6929
E-mail: robertsonde@nku.edu 

Dr. Robertson's research interests are broad. She has worked in both a marine environment on spiny lobster populations, and now on milkweed population recovery and management. The underlying theme is research at the population level regardless of the environment. she has and continues to explore the success of populations by better understanding population size over time, reproduction, growth and success of a population in the context of the greater environment in which they live. Her current research focuses on understanding the success of milkweed as this species of flowering plant is tied to the success of Monarch butterfly populations. Dr. Robertson is working with colleagues and students to better understand restoration and management impacts on the success of milkweed. They are also working to develop a sampling system using drone photography and GIS to map milkweed in restored areas over time and keep better track of population sizes and densities. Their goal is to promote better restoration and management of milkweed in hopes of positively impacting Monarch butterfly populations.

Emily Shifley

Office: SC 347| (859) 572-51409
E-mail: shifleye1@nku.edu

As a developmental biologist, Dr. Shifley is interested in understanding how organs develop in the early vertebrate embryo and she uses the African clawed frog, Xenopus laevis, as a model organism. Her research is focused on discovering and understanding the genetic signals that coordinate proper development. Even during early stages of development, embryonic tissues become differentiated from one another and eventually undergo morphogenesis to form the organs of the adult body. These tissues are guided by different molecular signals instructing them to differentiate into the various organs. Dr. Shifley's research is focused on discovering and understanding how these genetic signals coordinate proper embryonic development. This research is important because it can help explain why certain birth defects occur and it can help inform research aimed at directing stem cells into specific lineages for therapeutic purposes.

DAVID THOMPSON

Office: SC 246 | (859) 572-5301
E-mail: thompsone1@nku.edu

Research projects in Dr. Thompson's laboratory examine the physiological and toxicological implications concerning waterborne metals and organic herbicides. For example, Atrazine is an herbicide used in no-till farming and is frequently found in surface water such as within the Ohio River watershed. While atrazine has been shown to have adverse effects on non-target species, there is a lack of information examining the potential impact of commercially available atrazine products, especially considering the additional ingredients often included in these formulations. He research also lworks with studies of the physiology of squirrelfish, which have shown that female squirrelfish preferentially increase their uptake of Zn during reproductively active periods and make this Zn available to the developing embryo. Dr. Thompson's lab is examining the possibility that differential Zn-transporter expression occurs at critical points in the reproductive cycle, under hormonal control.

Lindsey Walters

Office: SC 345 | (859) 572-6390
E-mail: waltersl3@nku.edu

Dr. Walters research investigates the reproductive behavior of wild cavity-nesting birds. It seeks to answer broad questions about how birds navigate parental investment decisions to maximize their evolutionary fitness. Like all organisms that provide parental care to their offspring, birds face a tradeoff between investment in their offspring versus investment in their own self-maintenance. This fundamental tradeoff forms the basis for the research questions that she nvestigates with her students about parental behaviors such as nest site selection, incubation, nestling provisioning, and waste removal. Dr. Walters also uses birds to study conservation-related issues such as factors influencing bird-window collisions and the use of nestling feathers as a bioindicator of environmental methylmercury contamination. Undergraduate students are involved in every aspect of her research, including planning, data collection, analysis, presenting, and publishing.

Lauren Williamson

Office: FH 359F | (859) 572-1949
E-mail: williamsol6@nku.edu

Our brains determine almost everything we do and our brains get inputs from the outside world at remarkable speed. How do our bodies, and especially our immune systems and responses to pathogens, change our brains? How do our brains change what we do to survive infection and resolve inflammation? How does inflammation affect learning and memory? All of these questions drive Dr. Williamson's work in a rodent model of early-life infection. In her lab, they look at rodent learning and memory behavior and how that behavior correlates with inflammatory responses both outside and inside the brain.
