Ferreira, Tracie L. (Georgetown University, 1996 PhD)

Vertebrate development is a complex process involving numerous, tightly regulated signaling pathways. Growth factors and their receptors are some of the most influential genes and proteins regulating the various stages of development. Key to understanding the growth and development of the human body, is the use of other vertebrates to dissect the regulatory networks and then applying this information to human development. Common models for vertebrate development include mouse, chick and zebrafish. We use the zebrafish as a model for vertebrate development, and specifically to study Neural Crest Cell (NCC) development and specification as it relates to craniofacial development. We are also interested in the role of various growth factors during tooth development, specifically mineralization and how that process is disprupted by fluoride.

Hable, Whitney (University of Arizona, 1996 PhD)

My research focuses on the cellular and molecular mechanisms underlying cell polarization and growth. I am specifically interested the role the actin cytoskeleton plays in these processes, and how actin dynamics are regulated.

Cell polarization, the generation of asymmetry within a cell, is an essential event underlying many biological processes. For example, in many plant and animal embryos, polarity is established in the egg or zygote, and ultimately determines the basic organization of tissues and organs within the organism. I am investigating this process in zygotes of marine brown algae in the genera Fucus and Silvetia. In these model organisms, polarity is established in the zygote by the site of fertilization, and can be reoriented by environmental signals such as unidirectional light. Actin dynamics are essential for both fertilization-induced polarization and light-induced reorientation of polarity. Current research questions include: 1) Which protein pathways regulate the assembly of actin filaments? 2) What are the molecular mechanisms regulating actin mRNA and protein levels?

Hart, Peter E. (University Maryland, 1997 PhD)

Dr. Hart's research program is built around the use of cellular and molecular approaches to answer questions concerning the structure, function, and regulation of the cytoskeleton. Recently, his research has focused on the regulation of the small calcium-binding protein, centrin, during spermatogenesis in mammalian systems. He is interested in the spatiotemporal expression of centrin genes during normal development as well as the aberrant expression of these genes during tumorigenesis. Current projects include: analysis of the epigenetic factors that regulate centrin gene expression, analysis of the cell cycle-dependent expression of centrin genes, and resolution of centrin function during spermatogenesis.

O'Connor, Nancy J. (North Carolina State University, 1990 PhD)

Dr. O'Connor's current research focuses on the ecological impacts of the invasion of the Asian shore crab, Hemigrapsus sanguineus, on coastal ecosystems, particularly the potential effects of the Asian shore crab on resident crab species, the incorporation of the crab into food webs as both predator and prey, and habitat characteristics that stimulate or inhibit the settlement and metamorphosis of megalopae (late-stage larvae).

Many marine animals have complex life cycles comprising both planktonic larval stages and benthic juvenile and adult stages. My research focuses on habitat characteristics that stimulate or inhibit the settlement and metamorphosis of larval crustaceans, both in the laboratory and the field. My lab group is also investigating the ecological impacts of the invasion of the Asian shore crab, Hemigrapsus sanguineus, on coastal ecosystems. We are examining the potential effects of the Asian shore crab on resident crab species, and the incorporation of the crab into food webs as both predator and prey.

Rajaniemi, Tara K. (University of Michigan, 2001 PhD)

My research investigates the mechanisms that determine species diversity in plant communities. I am especially interested in explaining patterns of species diversity along environmental gradients. My work has included experimental approaches to separate the effects of aboveground and belowground competition on diversity in an old field and analytical approaches to tease apart the effects of species pools, long-term and short-term abiotic conditions, and species interactions on diversity in Israeli sand-dune communities. I am also interested in the strategies plants use to compete for patchy soil resources.

Stahl, Eli Ayumi (University of Chicago, 2000 PhD)

I study the genetics of natural variation; this area of evolutionary biology has a long history as well as explosive growth with molecular biology and genomics. My interests include two lines of inquiry, each in two systems. The lines of inquiry are (1) to infer population structure and history from DNA fingerprinting data, and (2) to identify genes and make predictions for gene function. The study systems are (1) plants including the genetic model Arabidopsis thaliana as well as plants of conservation/environmental interest, and (2) human pathogens.
Population structure has implications for conservation, molecular epidemiology and gene mapping. The plant genetics work focuses on disease resistance and drought resistance, where phenotypes are correlated with candidate gene DNA sequences. The human pathogen work involves discovering new genes in complete bacterial genome sequences, and studies of pathogen and vector strain genotypes across space and time.
I am looking for students interested in collecting and analyzing DNA variation data, or in genomics and other areas of bioinformatics. Please contact me!
