Faculty Research

See what we our biology faculty are working on.

As a biology student, you have access to many resources, perhaps none more important than our leading faculty. Experts in their fields, our faculty members are consistently performing research around the globe. Here are their stories.


Tandra Chakraborty, Ph.D., Associate Professor

Dr. Chakraborty focuses on three chief issues in the interplay between endocrinology and neurobiology:

  1. Changes in the estrogen receptors with senescence
  2. Changes with obesity
  3. The action of estrogen in the glucose homeostasis and apoptosis of cell in tissues subjected to hypoglycemic conditions.

Jonna Coombs, Ph.D., Associate Professor

Bioremediation is the use of living organisms (usually plants or bacteria) to clean up environments that have been contaminated with hazardous wastes. Dr. Coombs’ research in heavy metal bioremediation focuses on three major questions:

  • What kinds of bacteria are capable of bioremediation, and how do these bacteria survive in environments contaminated with hazardous waste?
  • What are the structural changes that affect the stability, catalytic efficiency and substrate specificity of the proteins involved in metal resistance?
  • How has horizontal gene transfer (HGT) played a role in the evolution of metal resistance and other environmentally relevant traits?

Michael D’Emic, Ph.D., Assistant Professor

Dr. D’Emic studies the evolution and ecology of dinosaurs and other reptiles. Each summer he leads fieldwork expeditions to dig up dinosaurs and other extinct animals in the western USA. He also studies how bones and teeth grow at the cellular level in a variety of animals.


James K. Dooley, Ph.D., Professor

Dr. Dooley’s research focuses on the evolution and systematics of fish, working on a worldwide group of primarily moderately deep-water fish (tilefishes; Branchiostegidae) comprised of 45 nominal species. He recently collected DNA from species from the Western Pacific coast of Japan, China, Taiwan, the Philippines and Vietnam and his secondary research includes consulting work with the United Nations (FAO) and the IUCN international Red List group working on world threatened and endangered marine species.


Matthias Foellmer, Ph.D., Associate Professor

Dr. Foellmer’s research interests include the evolutionary consequences of anisogamy (in particular the evolutionary significance of sexual dimorphism, gender roles, and sexual conflict), as well as the ecology of Long Island salt marshes, focusing on anthropogenic effects such as habitat fragmentation and pollution. Dr. Foellmer uses spiders and insects as model organisms.


Aaren Freeman, Ph.D., Assistant Professor

Dr. Freeman’s research interests are in marine biology, evolution and ecology of marine organisms, biology of invasive species, predator-prey interactions, phenotypic plasticity and trait-mediated indirect interactions.


Alexander Heyl, Ph.D., Assistant Professor

Dr. Heyl works on the evolution and function of signaling pathways. In particular, he is interested in the origin and in the molecular mechanisms of the signal transduction pathway of a class of plant hormones called cytokinins. Wet lab experiments and bioinformatics analysis tools are used towards these goals.


Lawrence Hobbie, Ph.D., Professor

Dr. Hobbie collaborates with Dr. Alexander Heyl in studies of the function and evolution of genes and proteins in the signaling pathway of the plant hormone cytokinin. Dr. Hobbie is also investigating teaching practices among the science faculty at Adelphi, and implementation of evidence-based instructional practices.


Alan Schoenfeld, Ph.D., Department of Biology Chair, Professor

Dr. Schoenfeld performs research on cancer genetics, in particular the class of genes known as tumor suppressor genes. His investigations have centered on uncovering the normal cellular function(s) of the protein products of the von Hippel-Lindau (VHL) tumor suppressor gene.


Aram Stump, Ph.D., Assistant Professor

Dr. Stump’s research involves the evolution of genes. He has studied how the iron-binding protein lactoferrin evolved to have an antibacterial activity in certain mammals. He’s also mapped the evolution of an important part of eukaryotic RNA polymerase II that is involved in the regulation of gene expression.


Eugenia Villa-Cuesta, Ph.D., Assistant Professor

Dr. Villa-Cuesta is interested in how genes and environment influence aging and disease, and her research uses Drosophila melanogaster and cultured cells to study the molecular mechanisms by which nutrition influences life span and health span.


Andrea Ward, Ph.D., Associate Professor

In her research, Dr. Ward incorporates evolutionary biology, functional morphology and developmental biology. She specializes in the evolution of the elongate body form in fishes, and she has examined the developmental origin of body elongation as well as the effect of body elongation on locomotion.


Benjamin Weeks, Ph.D., Professor

Dr. Weeks focuses on the effects of xenobiotics on the cellular mechanisms of development and disease.
