BIOGRAPHY AND RESEARCH INTERESTS
2014-Present: Assistant Professor, University of Texas at Tyler, Department of Biology.
We are interested in determining the genetic and environmental etiologic causes of the Autism Spectrum Disorders (ASD). Utilizing the zebrafish as a tool, we mutate and over express ASD risk homologs, identify phenotypes associated, and screen for molecules that may enhance or mitigate these phenotypes.
2008-2014: Postdoctoral Fellow in the laboratory of Dr. Daniel Geschwind.
We utilized morpholino oligonucleotides to reduce the levels cntnap2a, a homolog of the well established ASD gene CNTNAP2. We identified morphological and behavioral changes in the zebrafish, and identified a pharmaceutical capable of mitigating the behavioral phenotype. This paper is currently being revised.
2002-2008: Ph.D., MCDBG - in the laboratories of Drs. Lisa A. Schimmenti and Stephen C. Ekker.
We performed the largest morpholine screen conducted to date looking for the phenotypes of over 200 gene knockdowns. Specifically, I screened for developmental eye abnormalities. In addition, during the characterization of an enhancer trap line, we identified the choroid plexus, the organ responsible for regulating the constituents of the cerebral spinal fluid.
1999-2002: M.S., Biotechnology in the lab of Dr. Anthony Otsuka.
We were interested in the C. elegans specific isoform of the ankyrin family, unc-44. We performed biochemical experiments to look at it membrane localization.
1995-1999: B.S., Biological Sciences

Dr. Douglas Whitman - Functionality of the Comstock-Kellogg Gland.
Dr. Joseph Armstrong- Distribution of Pedicularis on an Illinois Prairie.
