Daleke Lab
We study molecular mechanisms controlling phospholipid organization in biological membranes in health and disease, with an emphasis on the effects of diabetes on membrane lipid organization and the characterization and identification of phospholipid transporters, or "flippases."
Foley Lab
Our lab studies the molecules that mediate hormonal control of skin development and how these factors contribute to cancer cell destruction of bone.
Hollenhorst Lab
In the Hollenhorst lab we study the mechanisms that ETS family transcription factors use to interact with the genome in an effort to delineate both normal and oncogenic functions of these proteins.
Hundley Lab
Our lab is interested in understanding how structured regions within mRNAs, specifically within the 3’ untranslated region (3’ UTR) affect gene expression.
Mescher Lab
We are interested in the cellular interactions required for tissue and organ regeneration and the focus of our work is the regenerating amphibian limb, which is able to regenerate completely following amputation.  Current work involves an analysis of gene expression during the period when regeneration begins and how this gene activity is regulated by factors released during inflammation.
My laboratory seeks to understand the paracrine and juxtacrine interactions between cancer cells and their microenvironment that regulate metastatic colonization in ovarian cancer
Cancer epigenetics (DNA methylation and chromatin remodeling). We are using microarray technology and mathematical models to explore the role of epigenetics in ovarian cancer cells and resistance to chemotherapy.  We also study breast cancer, estrogen receptor biology, and resistance to antiestrogens (breast cancer therapies).
Our lab studies the role of oxidative DNA damage in initiating cancer-specific epigenetic changes.
I am interested in the neural basis of behavior, particularly the neuroethology of acoustic communication. My research is primarily focused on the physiology of song production in songbirds and parrots
Walczak Lab
The Walczak lab is interested in the molecular mechanisms that govern mitotic spindle assembly and chromosome segregation in both normal and tumor-derived cells.
