Department of Biological Sciences
Biology is the scientific study of life: its diverse forms, processes, environments and systems. At Bridgewater, we prioritize hands-on biology learning in our well-equipped laboratories and through fieldwork and ecological studies in the multiple different habitats located close to campus.
Our goal is to provide undergraduates with a broad background that gives them career flexibility, and to provide graduate students with opportunities to develop skills and knowledge in more specialized areas.
Meri Krevosky joined the faculty of Bridgewater State University in the Fall of 2002. Her research interests focus on the study of programmed cell death, or apoptosis, of cancer cells. Cancer cells often acquire genetic mutations or express proteins that prevent cell death following therapeutic intervention (chemotherapy, irradiation). Therefore, the study of the mechanisms that underlie resistance to cell death may lead to the identification of novel targets for the treatment of cancer. Additional interests include the study of programmed cell death in ocular disorders to better understand how small heat shock proteins may prevent retinal cell death in retinoblastoma, destructive endophthalmitis and age-related macular degeneration. Dr. Krevosky’s primary teaching responsibilities include Anatomy and Physiology, Animal Physiology, and Cancer Biology. She enjoys mentoring students in cellular and molecular biology research and sharing with them the excitement of biological discovery.

These projects are pursued using mammalian cell culture as a model system alongside a variety of cellular, molecular, and biochemistry techniques. In addition to his teaching and research, Dr. Adams is chair of the Health Professions Advisory Committee, which provides support and guidance to BSU students considering and/or pursuing a career in the health professions.
Christopher Bloch joined the faculty of Bridgewater State University in the fall of 2006. His primary teaching responsibilities include General Biology II, Ecology, and Biometry (experimental design and statistical analysis in biological research). Dr. Bloch's research interests lie primarily at the population and community levels of ecological organization. Currently, the principal focus of his work involves the effects of natural (e.g., hurricanes) and anthropogenic (e.g., logging) disturbance events on population dynamics and community structure. Most of this work has used terrestrial snails as a model organism, but he has studied a variety of organisms, including whip spiders, rodents, and bats, in tropical and temperate systems. He also maintains an interest in the mechanisms that generate broad-scale patterns of biodiversity. He actively involves Bridgewater students in his ongoing research on the ecology of terrestrial snails in Puerto Rico as well as local projects focusing on effects of habitat loss and fragmentation.

M. Caitlin Fisher-Reid joined the faculty of Bridgewater State University in the Fall of 2014. Her research focuses on the beginning stages of speciation, phylogenetics, and population genetics. She is particularly interested in ecological speciation, in which divergent natural selection leads to reproductive isolation within a population. Dr. Fisher-Reid is currently exploring questions related to these topics in Plethodontid salamanders, in particular the very common eastern red-backed salamander, Plethodon cinereus. She has done extensive lab and field work to examine the genetics and ecology behind the separation of the two color morphs of P. cinereus, the red and the lead morph, on Long Island, NY. She is continuing this work in the southeastern Appalachians and in the northeast, where the morphs separate on elevational gradients. Her broader goal with this research is to explore the relationship between different kinds of genetic variation (e.g., adaptive, neutral) and environmental gradients, which has implications for conservation and speciation research. Dr. Fisher-Reid has also worked on phylogenetic methods, the phylogenetic history of the genus Plethodon, and climatic-niche evolution in the salamander family Plethodontidae, to which the genus belongs. You can learn more about Dr. Fisher-Reid and her research at http://webhost.bridgew.edu/mfisherreid/ .
Heather Marella joined the Department of Biological Sciences in 2011. Dr. Marella’s teaching responsibilities include General Biology II, Genetics, Plant Physiology and Parasitology. Dr. Marella’s research focuses on the interaction between plants (Arabidopsis thaliana and tomato) and a nematode parasite (Meloidogyne incognita). Meloidogyne incognita is a microscopic roundworm that penetrates the root of a host plant, where it establishes a feeding site; draining the plant of nutrients and altering the structure of the root. These devastating parasites cause an economic loss in the billions annually. Using a combination of genetics, cell and molecular biology, Dr. Marella and her undergraduate students investigate the function of plant transporter genes in establishing and maintaining the parasitic infection. Additional projects examine the role of plant hormones and mycorrhizal fungi in the plant-parasite interaction. Students have the opportunity to present their data at local, regional and national conferences.

Boriana Marintcheva joined the Biology Department in the Fall of 2008. Currently she teaches Cell Biology, Virology and Molecular Biology courses with labs. Her research interests focus on the biology of virus-host interactions using bacteriophage T7/ Escherichia coli model system. Knowledge about the specifics of virus-host interactions in different systems has allowed the development of preventive and therapeutic measures aiming at diminishing the negative impact of viruses on human health, and using viruses for practical purposes such as biotechnology and drug delivery. While bacterial viruses are harmless to humans, they function in similar ways to animal viruses and often employ simpler molecular machinery. Historically, many aspects of viral biology were initially understood using bacteriophages and then applied to the more complex systems of animal viruses. In her research, Dr. Marintcheva uses techniques from molecular biology, genetics and biochemistry. Dr. Marintcheva is also passionate about science education, science promotion and development of pedagogical tools advancing teaching and learning.
