After receiving a B.A. (Biology) from the University of Maine-Fort Kent in 1985, I earned a Ph.D. in Zoology (1991) from Indiana University. My research concerns the evolution, structure and behavior of animals, particularly fishes in the Family Cichlidae. Our laboratory also has ongoing investigations of vertebrate developmental anatomy and projects investigating the behavior and physiology of freshwater turbellaria (planaria). My teaching assignments have included a wide range of topics, including Human Anatomy and Physiology, Vertebrate Anatomy, Zoology, Embryology, Evolution and Marine Biology.

I am a native of central Connecticut, but have lived in northern and coastal Maine, southern Indiana, and the eastern shore of Virginia, as well as western Pennsylvania.

Education:

Ph.D. Genetics, Michigan State University

M.S. Molecular Genetics, Saint Louis University

B.A. Biology, Classics and Philosophy, Saint Louis University

Teaching interests:

I teach a variety of courses, including genetics and molecular biology. My courses not only convey important foundational information about biological processes, but also require a high level of assimilation of the information. My hope is this educational experience will equip students with critical thinking skills that will help them succeed in all their endeavors.

Research interests:

The DNA of an organism contains most of the information necessary for life. How this genetic information is decoded to produce the characteristics of life is a central process of biology. The general molecular basis for this process is that a DNA polynucleotide called a gene is transcribed into an RNA polynucleotide (i.e., transcription). In many cases, the RNA polynucleotide is translated into a protein. Proteins are functional molecules that produce most of the features of life. However, many questions remain as to how this flow of genetic information is controlled. My lab focuses on better understanding of how gene transcription is activated. To this end, we utilize biochemical, genetic and optical approaches to study the Drosophila melanogaster heat shock genes as a model system for transcription activation.

I have been teaching since 2010 and joined the faculty at Slippery Rock University in 2017. My teaching experience spans both undergraduate and graduate level courses and has included lecture, laboratory, distance education, and problem-based learning modalities. My primary area of expertise is in Neuroscience and my current teaching responsibilities revolve around courses in human Anatomy and Physiology.

My prior experience spans several fields including Neuroscience, Medical Education, Psychology, and Music. I believe this gives me a unique opportunity to connect with students pursuing a variety of careers in the biological sciences. This wide-reaching set of interests has also led to an assortment of research paths, including projects in developmental ethanol exposure, chemosensory plasticity, spinal cord injury, and osteopathic manipulative medicine. As I enjoy assisting students in developing projects that incorporate their own areas of interest, recent research has further expanded to incorporate new technology in the investigation of relationships between music and brain activity.

I earned a B.S. in Biology from Allegheny College and then a Ph.D. in Pharmacology from the University of Pittsburgh. For my dissertation research, I investigated the roles of the estrogen receptors and nuclear matrix in breast cancer development and resistance to the therapeutic agent, tamoxifen. I completed a postdoctoral fellowship at Lawrence Livermore National Laboratory in Livermore, CA where I used the technique of Accelerator Mass Spectroscopy to investigate several different biological questions such as the activity of cancer stem cells and the transport of low concentrations of endocrine disrupting compounds across the placental barrier. My current research interests lie in cancer biology and endocrine disruption. I have worked with many undergraduate students in research and look forward to working with more SRU students.

I have been an instructor at Slippery Rock University since the fall semester of 2014 and then became an Assistant Professor in the fall semester of 2018. I currently teach courses in Human Anatomy and Physiology.

My research in animal physiology concerns the effects of environmental change, notably degradation of aquatic ecosystems, on wildlife health. Current studies in our laboratory address the effects of chemical contaminants (water pollution) on endocrine and immune processes in amphibians. Amphibians are currently experiencing dramatic global population declines and more information is desperately needed to slow and halt this trend. In addition, similarities between the physiology of amphibians and other vertebrates make them excellent models for the effects of environmental change on animal health, including our own. My studies actively involve students with a broad spectrum of animal health interests.

I earned my Bachelor of Science degree in zoology and botany at the University of the West Indies (UWI), Mona Campus, Jamaica, W.I. I also pursued my Master of Science degree in zoology, which was upgraded to a Ph.D. in zoology at UWI. The title of my Ph.D. thesis was ‘Laboratory Studies of the Activity of Extracts of Selected Jamaican Plants against Infective Larvae of Strongyloides stercoralis (Nematoda)’. I completed a three-year postdoctoral fellowship (2000-2003) in the Schad research laboratory, Department of Pathobiology, Parasitology Laboratory, School of Veterinary Medicine, University of Pennsylvania. There, I used laser microbeam techniques to investigate functions of amphidial neurons in parasitic nematodes, including Strongyloides stercoralis, Haemonchus contortus and Ancylostoma caninum. My current research interest lies in the area of parasitology where I pursue chemotherapy studies using eryngial, a bioactive compound that I had previously identified and chemically isolated from the plant Eryngium foetidum. Eryngial is being investigated for activity against parasitic nematodes and other organisms. Additionally, I am also interested in the bioactivity of eryngial-related compounds against parasitic organisms.

I started teaching as an Assistant Professor of Biology in the Department of Biology, SRU in August 2003, and became an Associate Professor in August 2014. I also served as Chairperson of the Department of Biology, SRU, from June 2015 to May 2017. I was the APSCUF Department Representative from 2004 to 2015, and the Coordinator of the Medical Technology, Cytotechnology and Histotechnology series from May 2015 to September 2015. These positions were both relinquished to colleagues in the department when I became the Chairperson.

As instructor in the Department of Biology, I have taught the following majors courses: Principles of Biology, Medical Parasitology, Biology Seminar and Independent Study. I have also taught the following non-majors biology courses: Introductory Biology Laboratory and General Biology. Additionally, I have taught courses offered outside of the department, these being the FYRST Seminar and the newly developed Science of Life.

Over the years I have had several students doing parasite research investigations with me on a variety of topics via independent studies. Most recently, I had two students who investigated the activity of eryngial against Neospora caninum, a protozoan parasite that is major cause of abortion in cattle, and accounts for annual losses to the meat and dairy industries that are worth billions of dollars.

Teaching interests:

My teaching includes Biology II (Foundations of molecules, genes and cells), Genetics, Science of Life, and other courses.

Research Interests:

My scientific interests lie at the intersection of cell biology, genetics, and evolution. My primary research focus is currently aimed at understanding how cells manage the active accumulation of nutrients across their the plasma membrane. I use brewer’s yeast (Saccharomyces cerevisiae) as well as its evolutionary distant cousin Schizosaccharomyces pombe as model systems, because of their well understood cell biology, genetic flexibility, and ease of use in an undergraduate research environment. My lab focuses on studying how individual membrane pumps can be activated or removed by regulated endocytosis. We use CRISPR-Cas9, confocal microscopy, molecular cloning, and high thruput genetic screens to dissect the molecular details of how membrane pumps interact with their endocytic adaptors. Not only are the molecular details of these systems intrinsically interesting, but by using diverse model systems to study these deeply conserved process, (which are universal to all eukaryotic cells including humans) my lab’s long term goal is to be able to infer universal design principles, with potential widespread applicability for both basic biology and human health.

I am also interested in using genetics to trace the evolutionary trajectories of populations, on both the local and deep-time scales. To that end I am developing genotyping methods to study the dispersal of moss in log-fall microhabitats as a new model system to study ecological succession and colonization.

I have been a faculty member at Slippery Rock University since the fall of 2009. I teach courses for biology majors in Cell Biology, Medical Immunology and Principles of Biology. I also serve as the coordinator for the medical technology, histotechnology and cytotechnology 3+1 degree tracks. My research focuses on sugar metabolism and neurodegeneration (brain cell death). I utilize yeast and fruit fly models to look at how altered metabolism can affect cellular health. I frequently have 4 or more students working in my laboratory on research projects and they often present their research at state and national meetings sponsored by the Genetics Society of America and the American Society of Biochemistry and Molecular Biology. In addition, a number of students are co-authors on peer reviewed publication of their research here at SRU in my laboratory. Prior to joining the faculty at SRU I had a postdoctoral research position in the Department of Pharmacology and Chemical Biology (Program in Neurodegenerative Diseases) at the University of Pittsburgh.

Teaching Interests:

My teaching interests lie in the fields of physiology, anatomy, and related subjects.

Research Interests:

I am a broadly trained biologist who has experience working with both plants and various animal models. Over the years, I have developed a strong interest in cardiovascular physiology and development as well as the effects of electronic cigarette vapor on the cardiovascular system. The relative novelty of these products and their immense popularity warrants further investigation to better understand their impact on health and development. Previously, I have studied the effects of flavored electronic cigarette vapor with, and without, nicotine (as well as individual chemical compounds identified in the vapor) on the developing cardiovascular system using zebrafish embryos. Currently, I am planning to expand on these studies by utilizing the fruit fly model to examine the effects of electronic cigarette vapor exposure on the heart of both adult and larval fruit flies.

I earned all my degrees (B.Sc.: Histology/Zoology, B.Sc. Hons: Histology, Ph.D.: Anatomical Sciences) at the University of Adelaide, Australia – a place where there is no snow! After which I completed a Postdoctoral Fellowship in the Department of Anatomy at the New York College of Osteopathic Medicine, where my primary duty was to teach cadaver-based human anatomy to medical and allied health graduate students, before coming to Slippery Rock University in 2000. Since coming to SRU I have developed a research program involving many undergraduate students, resulting in numerous publications, grants and presentations.

As a comparative anatomist (specializing in histology), I began my research career examining the comparative histology of orbital glands in squamate reptiles and their association with nasal sensory organs, specifically the Vomeronasal Organ. Since coming to the US, I have added in experimental data, comparative observations (alligators, mammals, amphibians and birds) and developmental research. As a result, my research focus has broadened to include the development and route of the nasolacrimal apparatus in tetrapod vertebrates.

I am a plant ecologist, specializing in wetland and aquatic plant communities. Wetlands are diverse ecosystems found worldwide and go by a variety of names such as marshes, swamps, fens and bogs. Regardless of name, all wetlands are dominated by flooding, which has strongly shaped the traits of plants living there. Aside from flooding wetlands, water also connects wetlands to the landscape by moving pollutants and other materials from the landscape into wetlands. This connectivity makes wetlands and wetland plant communities particularly vulnerable to environmental degradation.

Here at SRU, my lab tries to better understand what limits plant distributions and abundances, particularly in aquatic systems that are highly impacted by humans. We develop questions and hypotheses based on theory and applied science and conduct observational and experimental research. Our work takes us from the edges of ponds and lakes to ditches in farm fields and cities to herbarium collections worldwide. Our research is strongly quantitative and interdisciplinary.

I have been a faculty member since the fall of 1992. My primary teaching responsibility has been Genetics (41 times and counting). I have also taught Principles of Biology, General Biology, and Introductory Biology many times, along with Social and Ethical Issues in Genetics, Molecular Biology, and Evolution. I have published research on the coiling of pea tendrils, the uptake of amino acids by mammalian cells, the cloning of genes from Chinese hamster ovary cells, and the analysis of the seed storage protein genes of oats and maize. My current interests outside the classroom are maize genetics, ethical issues in genetics, genetics education, and the history of genetics and the eugenics movement.
