WhatI study how neural circuits process temporal information; specifically, how the bat auditory system is able to distinguish, with high temporal precision, different durations of auditory signals and echolocation calls.
HowI build computational models of neural circuits to test and explore different neural mechanisms. I observe the in vivo system via extracellular electrophysiological recordings.

Software ProjectsSpikeDB is an application to archive, manage, and analyze data from electrophysiological recordings saved with Spike. Users are able to write custom analysis scripts in Python that operate on single, or multiple, electrophysiological recordings to quickly run arbitrary analysis across large quanities of recorded data. Written with the GTK+ GUI library in C++, SpikeDB is cross platform.
dtnet [Linux; Github]dtnet is a an artifical neural network simulation environment written from the ground up. Networks and stimulus patterns are defined in XML files and simulation definitions are written in a custom language parsed by Boost Spirit. I wrote this software to run a large number of simulations in parallel and perform large parameter space searches. dtnet automatically generates and runs all simulations across arbitrarily defined parameter vectors. Software was used to run simulations in Aubie et al. (2009).
Sound Artist [Mac OS X; Github]Sound Artist permits auditory researchers to quickly and accurately produce publication quality figures of sound files with built in methods for plotting waveforms, spectrograms, and power functions all with a variety of adjustable setings. Uses the powerful GLE graphics engine for producing high quality EPS output files.
mySportSite [Online; Website]In 2000 I started writing websites for local hockey teams. Over the next seven years, this exploded into mySportSite Inc., a company that provided easy to use, professional, affordable websites for hundreds of sports teams and leagues all over the world. In 2008 I decided that it was time to move on from the web business and focus on my research. The company is still going strong in able hands and continues to grow to this day.
