John W. Martinson

Currently I am pursuing a Ph.D. in bioinformatics at the University of Cincinnati, leaving my previous as Quality Assurance Manager in 2004. I am working on several projects that use molecular markers (DNA barcodes) to identify fish species. The barcodes can be used as a quality assurance tool on projects that rely on morphology-based identification of fish specimens (e.g., large river bioassessments), and also as a means to correctly identify difficult samples such as larval fish. Most of my future efforts will be focused on moving next generation DNA sequencing (454 pyrosequencing) into bioassessments of aquatic environments. The primary goal is to develop tools that use DNA sequences from bulk extractions of environmental samples to determine the community composition (biodiversity) present in the samples, and to correlate such results with other measures of condition in order to better understand the full impact of various stressors on the environment.
