I study the physics of voice production—how airflow, tissue mechanics, and acoustics interact to create the human voice. Over three decades, this work has moved from mathematical models of vocal fold oscillation to tools that put research-grade analysis in the hands of clinicians. I build PhonaLab, a free web platform for acoustic voice analysis used by 1,200+ clinicians and researchers in 60+ countries, and SimuVox, a physics-based voice synthesizer for simulating disordered voice quality.
Free web-based acoustic voice analysis for speech-language pathologists. Implements validated multiparametric indices (AVQI, ABI, CSID, CPPS) via Parselmouth/Praat. Features include Voice Analyzer, Pitch Visualizer, Spectrogram Generator, Spectral Analysis, and Session Compare. No installation, no audio storage, works in the browser.

Physics-based voice synthesis software. Models vocal fold vibration, glottal aerodynamics, and acoustic propagation in a 44-tube vocal tract. Used for research on disordered voice production and perceptual assessment training.

My research centers on the biomechanics and acoustics of phonation: vocal fold oscillation dynamics, phonation threshold pressure, source-tract acoustic coupling, and speech articulatory patterns. Current work focuses on acoustic correlates of perceptual voice quality dimensions and controlled simulation of voice disorder mechanisms.
