Biography
Ashwin received a BA in Biophysics at Johns Hopkins University (2007) and a MA/MS in Biology/Marine Biology at Northeastern University (2009). Before entering the PhD program at the University of Washington he was a Research Associate at Duke University in the lab of Sonke Johnsen (2009-2010). Ashwin joined the Sisneros lab in the Fall 2010. He graduated with a Ph.D. in Psychology (Animal Behavior) in Spring 2016. Currently Ashwin is a postdoctoral associate at the National Institutes of Health.

Research Interests
Ashwin is interested in understanding how dynamic environments shape sensory performance. His work focuses on hearing sensitivity in larval fishes during ontogeny and after acute noise exposure. Ashwin's work has led to the development of a behavioral assay using prepulse inhbition (PPI) of the acoustic startle response to measure auditory thresholds in 5 dpf zebrafish. This assay has been used to show that auditory sensitivity at frequencies above 90 Hz are not dependent on the lateral line in these animals. Ashwin's dissertation work focuses on the effects of acute noise exposure and its effects on startle response sensitivity and loss of PPI.

Ashwin is also an associate organizer of the Beneath the Waves Film Festival (www.beneaththewavesfilmfest.org)
