Current position: self-employed


Ph.D. Molecular Biology (with an emphasis in Rumen Microbiology), New Mexico State University, 2005
B.S. Biology, Truman State University, 1996


In this lab, we are interested in the emergence of auditory and vestibular endorgans from the otic vesicle of the amphibian, Xenopus, with an aim to identify genes essential for inner ear function and development. My contribution will involve microarray and bioinformatics analyses to study juvenile Xenopus laevis inner ear gene expression patterns and uncover the cohorts of genes responsible for inner ear function. I have compiled a database of genes identified from auditory research literature and microarray data from human, mouse, and avian inner ears to compare with the Xenopus inner ear transcriptional profile. I also want to establish a list of Xenopus inner ear genes that have a high degree of similarity to genes that cause deafness in humans.
