Biology faculty in lawn


Mrs. Chris Ferris -; Department Secretary, 610-683-4307, Boehm 223


Dr. Angelika Antoni -; 610-683-4319   Immunology, microbiology, and molecular biology, with interests in the genetic basis for human diseases, cell signaling, and the consequences of cellular apoptosis. Her main goals are to elucidate the genetic basis of autoimmune predisposition for diseases such as lupus and type I diabetes; and to determine how the infant intestine becomes populated with microbes that are necessary for healthy development.

Dr. Daniel Aruscavage -; 610-683-4315   Food safety in the home, such as contamination of cutting boards and sponges, is studied.  Several other aspects of microbiology are also considered, such as antibiotic resistance, water quality, and microbial physiology.

Dr. Marilyn C. Baguinon -; 610-683-4324   Interests are in understanding gene function using molecular biology techniques. Examples of genes/proteins she has worked on are those involved in nitrogen fixation, in bacterial endotoxin detoxification, and blood clot formation. Recently, she has been involved in research studying the function of certain genes involved in red flour beetle development. 

Dr. Douglas Becker -; 484-646-5861   Conservation biology and avian and landscape ecology with an emphasis on how biological communities change within human modified environments and management strategies to balance human and wildlife needs.

Dr. Nancy M. Butler -; 610-683-4791   Freshwater and marine ecology, including plankton feeding strategies, mating behavior, physiology, and community structure.

Dr. Christopher Habeck -; 610-683-4318   Conservation biology, restoration ecology, and plant-herbivore interactions. I am interested in 1) how plant chemistry influences consumers, 2) how consumer foraging choices impact invasion dynamics, and 3) how consumers influence restoration success through alterations to the compositional and chemical signature of plant communities. My work integrates around a larger theme of enhancing basic and applied ecological knowledge for the conservation of species, habitat restoration, and mitigation.  Lab Webpage

Dr. Richard Heinemen -; 610-683-4331   Genetic and phenotypic evolution of bacteriophages.   I study how bacteriophages, viruses that infect bacteria, adapt both genetically and phenotypically. Their short generation times and large population sizes make it possible to study evolution in action. Special interests include the genotype-phenotype map and life history evolution.

Dr. Alexander D. Hernandez -; 484-646-5861   Ecology and evolution of parasite-host interactions in wildlife populations from aquatic and terrestrial ecosystems.  Research focuses on understanding life history strategies important for transmission of gastrointestinal parasites and how environmental changes, such as global climate change, pollution and landscape alterations alter parasite interactions with hosts.

Dr. Angela Hoptak-Solga -; 610-683-4311   Cell and molecular genetics with an emphasis on the mechanisms responsible for the control of bone growth in zebrafish caudal fins. In particular, I study how mutations in connexin43 (cx43) lead to the production of short fins. I am interested in analyzing bone and joint structure using electron microscopy.

Dr. Carol C. Mapes -; 610-683-4308   Chair of the Biology Department.   Plant physiology, plant growth and development, and cecidology.  Research focuses on studies involving plant galls caused by insects and mites.

Dr. Cristen Rosch -; 610-683-4313   Plant molecular and cell biology, developmental biology with interests including gene expression, gene regulation, and the use of fluorescent microscopy to study the cellular cytoskeleton.

Dr. Wendy L. Ryan -; 610-683-4310   Diverse projects within marine biology with an emphasis on zooplankton physiology in response to high pressure and other environmental stressors and marine mammal behavior and physiology. Lab Webpage

Dr. Christopher F. Sacchi -; 610-683-4314   Reproductive biology of native and introduced plant species with a focus on abiotic and biotic factors influencing plant growth and reproduction.  Plant-herbivore and plant-pollinator interactions are of special interest.

Dr. Gregory P. Setliff -; 610-683-4316   Insect taxonomy and systematics, especially of tropical weevils from the Indo-Australian region; related interests include documenting biodiversity, insect identification, invasive species, and tropical ecology.

Dr. Matthew Stone -; 484-646-5844   Physiology, ecology, and conservation of reptiles and amphibians.  His research focuses on bone dynamics of turtles, specifically in relation to reproduction. Lab Webpage

Dr. William F. Towne -; 610-683-4317   Communication, learning, and sun-compass orientation in honey bees.

Dr. Robyn Underwood -; 484-646-5853   Focuses on aiding beekeepers in managing honey bee pests and diseases.  I am also involved in efforts to document winter losses across the country.

Dr. Todd Underwood -; 610-683-4323   Bird behavior and ecology with a focus on the interactions between Brown-headed Cowbirds (a brood parasite that never raises its own offspring) and its hosts.  Other interests include the impact of alien plants on birds, biology of birds using artificial nest boxes, and bird feeder hygiene.
