Ryan Mulqueen

Ryan Mulqueen

Ryan Mulqueen graduated from SUNY Stony Brook University in 2014 with a B.S. in Interdisciplinary Biology. While in his undergraduate studies, he had varied research interest. He began his research career studying the formation of social hierarchies in African cichlids in the lab of Ivan Chase, Ph.D., where he helped develop the system to codify behaviors of dominance. He then moved on to study the speciation of native drosophilids under the instruction of Walter Eanes, Ph.D. This work became the focus of his undergraduate thesis, in which he analyzed the morphology of drosophila sex-combs intraspecifically, interspecifically, and in previously undocumented interspecies hybridizations. Ryan joined OHSU's graduate program in Molecular and Cellular Biosciences in the fall of 2014. In the spring of 2015, Ryan became a member of the labs of both Brian O'Roak, Ph.D. and Andrew Adey, Ph.D., under a joint-mentorship program. Ryan is interested in studying the roles of somatic mosaicism and epigenetic factors in the developing brain. To this end, Ryan's ongoing work involves the improvement of high-throughput single-cell epigenetic protocols and enhanced neuronal population targeting in transgenic lines.

Daelyn Richards

Daelyn Richards

Daelyn was raised in Sugar Land, Texas and moved to the Pacific Northwest when she was a senior in high school. She received her Bachelors of Science with honors from Portland State University in 2014 and quickly matriculated into the Program of Molecular and Cellular Biosciences here at Oregon Health &Science University. She joined the Harding Laboratory in the Molecular and Medical Genetics Department and is passionate about improving therapies for people with rare disorders. Her primary focus is centered around gene therapy efforts for the treatment of phenylketonuria, the most common inborn error of metabolism, which is currently treated with life-long dietary management. When patients go off of this arduous diet, they suffer severe neurological complications. For her thesis, she aims to address the current limitations of PKU gene therapy to help facilitate its movement into the clinic. In her spare time, she likes to compete in triathlons and marathons, explore nature around her home in Camas, and play with her five Labrador Retrievers, Cordelia, Dallas, Lily, Marley, and Abigail.
