1995-present Associate Professor of Biology, Lawrence University. Study of the molecular basis of development using chick and zebrafish model systems. Interests include exploring the fundamental molecular basis of development and understanding how the molecular basis of development can provide insight into mechanisms of evolutionary change. Current projects are focused on the role of vg1/mgdf1/zdvr1 control of left-right asymmetry using zebrafish as a model system. Please see the expanded statement later in this document. I have directed 48 students (27 since tenure) in summer or independent research.
1994-1995 Postdoctoral research, Vanderbilt University, Dr. Brigid Hogan, mentor.
Using the chick embryo as a model system, demonstrated that several of the key genes involved in limb bud development are also expressed in the branchial arches. Additionally, investigated the role of the TGF-beta related gene, bmp-4, in neural development by misexpressing this gene under the control of a heterologous promoter in transgenic mice.
1989-1994 Doctoral dissertation, Vanderbilt University, Dr. Brigid Hogan, advisor. Studied the role of the TGF-beta related growth factor, bmp-6, in embryonic development of the mouse. Emphasis was on the expression and effects of bmp-6 in the developing nervous system. In addition, produced a polyclonal antibody against hoxb-5(2.1) and used it to study expression and biosynthesis of this homeoprotein in vivo.

Current Research Interests and Activities
I have a long-term goal of understanding the role of secreted signaling proteins in differentiation and patterning of vertebrate embryos. My current research interest is investigating the role of genes encoding these proteins. More specifically I am focusing on the role of vg1, and its orthologs, in establishing the left-right asymmetry of the internal organs in vertebrates. The vg1 gene was originally identified in the frog. Orthologous genes have been identified in fish (zdvr1), chick (cvg1), mouse (mgdf1), and human (gdf1). My previous research identified the mouse ortholog and demonstrated that the mouse gene (mgdf1) functioned similarly to the frog gene (vg1) when injected into frog embryos. To further demonstrate the evolutionary significance of these genes, I plan to extend this work by conducting gain of function and loss of function experiments. I will use the mouse gene (mgdf1) and the fish gene (zdvr1) to demonstrate that these orthologous genes function similarly the frog gene (vg1). Loss of function experiments with zdvr1 are in progress.
Additionally, I plan to examine the mechanism(s) that control the expression of the functional protein product of these orthologous genes. To date, only the mRNA expression pattern has been determined. However, we know from biochemical evidence that the production of functional protein from the mRNA of vg1 is tightly regulated. This is apparently the case for mgdf1 and presumably for zdvr1 and cvg1 as well. Therefore, I plan to generate a fluorescently labeled ZDVR protein by producing a zdvr1 gene with a green fluorescent protein (gfp) gene fused to it. This chimeric gene will be injected into fish embryos and we will be able to visualize the fluorescent protein with confocal microscopy. Since the fluorescent protein is fused to the ZDVR protein, visualization of fluorescence will indicate the location of ZDVR. I am currently collaborating with Dr. Barbara Sisson at Ripon College to produce the fluorescently labeled zdvr1 gene
