Nick Lozier, Ph.D. 
University of Washington
Department of Psychology
316 Guthrie Hall
Seattle, WA 98195

Graduated Summer 2020




Nick graduated with a B.S. in Biological Sciences from Ohio University in 2013. As an undergraduate he assisted in multiple projects in the lab of Dr. John Kopchick who uses several genetically manipulated mouse models of growth hormone disorders to research the role of growth hormone in obesity, diabetes, and aging. Following graduation, Nick continued researching at Ohio University for an additional two years as a research assistant in the Department of Biomedical Sciences working in the lab of Dr. Sonsoles de Lacalle. His primary aim in the de Lacalle lab was determining the utility for pharmacological inhibition of myostatin (a muscle growth inhibitor) for treating muscle wasting diseases using a myostatin knockout mouse model. Nick joined the Sisneros lab at the University of Washington in September 2015. Nick graduated with a Ph.D. in Psychology (Animal Behavior) in Summer 2020. Currently he is a postdoc in the lab Dr. Maria Rubio at the University of Pittsburgh.​

Nick is primarily interested in reproductive state-dependent and ontogenetic changes in the inner ear of the plainfin midshipman fish. Specifically, he is interested in reproductive state-dependent changes in hair cell density of the saccule and the ontogeny of inner ear saccular development in the plainfin midshipman. In addition, Nick is also interested in the auditory evoked behaviors of juvenile midshipman in the context of anti-predator avoidance behaviors.
