Since July 2020, I have been an audio engineering project manager at Apple.

2011-2020: I was a senior research scientist and program manager at GN, where I led 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.

Ph.D., Biomedical Engineering - Purdue University (2013)
     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".

  • MPEG Committee (Represented the University of Miami at MPEG Meetings)
    • Conducted Listening Tests for Spatial Audio Coding
    • Worked with others to define standards and develop an audio library
  • Adaptive Feedback Reduction (Implemented an adaptive filter that removes acoustic feedback)
  • Comparison of Cochlear Filter Banks (Compared Lyon's auditory filterbank with the ERB model. Note: I now realize there were several problems with this study. For instance, the 3 things I was comparing were very different things and probably should never have been compared in this way.)
  • MPEG Psychoacoustic Model 2 for Matlab (Click HERE for the code.)
  • Audio Steganography (Hiding data in an audio signal... included noise shaping and lossless compression)

B.S., Electrical Engineering - University of Illinois at Urbana-Champaign (2003)
     Senior Design Project: "Audio Spatializer for Headphones"

  • Perceptual Audio Coding (Learning to implement coders like MP3, AAC, AC3, etc.)
  • Psychoacoustics (Imlementing various principles of psychoacoustics in Matlab)
  • Audiovisual Speech Recognition in Automotive Environment (A project at The Beckman Institute that used 2 cameras and 2 microphones to enhance speech recognition)
  • Automotive Hands-Free Telephones (echo-cancellation, noise-reduction, objective analysis of audio quality)
  • Surround-Sound Headphones Used MIT's HRTF data to create a virtual 3D environment
  • Using FFT's as Band-Pass Filters
  • Determing Loudspeaker Response (reference: C.A. Ewaskio and O.K. Mawardi (1950), "Electroacoustic Phase Shift in Loudspeakers." Journal of the Acoustical Society of America 22(4):444-448.)
  • Sound Analysis/Synthesis Techniques (reference: R.J. McAulay and T.F. Quatieri (1986), "Speech Analysis/ Synthesis Based on a Sinusoidal Representation." IEEE Transactions. ASSP 34(4):744-754.)
  • Pitch Perception (reference: J.C.R. Licklider, "A Duplex Theory of Pitch Perception." Experientia VII(4):128-134.)
  • Basic Audio Coding (reference: Noll, "MPEG Digital Audio Coding," IEEE Signal Processing Magazine, Sept. '97.)
  • Advanced Coding Techniques (includes Water-Filling Bit Allocation and Sub-Band Quantization Using Signal-Mask Ratio)
  • Speech Recognition (reference: Steven P. Davis and Paul Mermelstein, "Comparison of Parametric Representations for Monosyllabic Word Recognition in Continuously Spoken Sentences." IEEE Transactions ASSP 28(4):357-366.)
  • Adaptive Filtering
