research

I want to know how brains work. I currently use the visual system as a model for understanding how brains process sensory information. I have training in electrical engineering, signal processing and neuroscience.

For my doctoral degree I made observations of bat flight behavior and mathematically modeled the flight strategies they use to capture insects. I designed and built apparatus to measure the sonar beam patterns of flying bats. I showed how the bat's acoustic gaze (where it directs its sonar beam) is related to its flight pattern. This work was done with Cynthia Moss, Timothy Horiuchi and PS Krishnaprasad at the University of Maryland, College Park.

outreach

I love sharing my joy of science with others.
I wrote this piece on bats on invitation from Imagine magazine. It is meant for a lay audience.
I wrote this piece on my student life in Maryland on invitation from the International Society for Neuroethology for the society newsletter.
I have judged several science fairs, and have been to several elementary and middle schools in Maryland with my PhD. advisor Cynthia Moss to talk about bats.

The idea that bats use a parallel navigation strategy similar to guided missiles made for good copy on The Hindu, Science Daily and other parts of the internet.

The sonar beam animations gained notoriety by winning first prize (non interactive media) in the Science and Engineering Visualization Challenge hosted by Science magazine and the NSF. The word diptych, if you wondered like I did, means any object with two flat plates attached at a hinge.
