Since 2011, I have been a research scientist at GN Advanced Science, where I am a principal investigator on several projects relating to hearing science and digital signal processing.
2007-2011: Ran a consulting business (LSB Audio, LLC) part-time while working on my PhD.
2003-2007: DSP Engineer at Shure Incorporated where I contibuted to a couple Advanced Development projects. I was a summer intern in 2003 & 2004, then a full-time employee from May 2005 through August 2007.
2000-2002: Three summer internships at Motorola doing everything from reverse engineering other company's cell phones to designing the audio system for OnStar.
1998: Spent the summer after highschool doing electronics assembly and repair at DriveCon.

Thesis: "Effects of Hearing Aid Amplification on Robust Neural Coding of Speech"
M.S., Music Engineering - University of Miami (2005)
Thesis: "Auditory Component Analysis: Using Perceptual Pattern Recognition to Identify and Extract Independent Components From an Auditory Scene".
B.S., Electrical Engineering - University of Illinois at Urbana-Champaign (2003)
Senior Design Project: Designed a portable audio spatializer for headphones (using Dolby algorithms on a 56k DSP)
Project Management Professional (2010-Present)
Masters Certificate, Project Management - The George Washington University, Washington D.C. (2009)
Applied Management Principles ("Mini-MBA" Course) Purdue University, West Lafayette, IN (2008)
Certificate, Electronic Equipment Repair Lake County Area Vocational Center, Grayslake, IL (1998)
My passion is studying audio perception, both behavioral and neurological. By combining my knowledge of psychoacoustics and auditory neurophysiology with my experience in digital signal processing, I enjoy creating technologies that improve audio quality.
I'm slowly working on a wiki of auditory knowledge. Check out the (very) early form at http://www.perceptualentropy.com/wiki
