Graduated Autumn 2017

Rob Mohr was a UW Biology undergraduate researcher in the Sisneros lab from 2009-2010. He joined the lab as a graduate student in the Fall 2011. Rob graduated with a Ph.D. in Psychology (Animal Behavior) in Autumn 2017. Currently he is employed at Amazon Spheres.

Rob's research focused on the role of the swim bladder for sound reception and communication in the plainfin midshipman. His work involved a combination of field work and controlled laboratory experiments that investigates the neural basis of communication in the soniferous midshipman.
