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.
Ashwin's main research interests are in the mechanisms
of sound perception in fishes and their behavioral effects. His work currently
focuses on hearing sensitivity during ontogeny in larval zebrafish and
sticklebacks. He is also interested in how female midshipman fish can
discriminate between multiple male advertisement calls in their shallow
water breeding environment. Ashwin also plans to explore the salient acoustic
cues of the male advertisement calls that are attractive to females, and
how males maximize their calling efficiency.
