Hassan Arbab

M. Hassan Arbab is an Assistant Professor in the Department of Electrical and Computer Engineering at Stony Brook University. His research focuses on advancing terahertz (THz) emission, detection, and imaging technologies with applications in biophotonics, medical imaging, non-destructive testing, and material characterization. His work integrates electro-optic theory, instrumentation development, and signal processing to overcome challenges in imaging through scattering media and enhancing diagnostic accuracy.

Key research areas include THz polarimetric imaging for burn wound assessment, carbon fiber composite analysis, and corneal imaging. He developed the Portable Handheld Spectral Reflection (PHASR) scanner, a portable device enabling clinical applications in burn triage, material defect detection, and medical diagnostics. His team employs machine learning and physics-based models to interpret THz data, achieving breakthroughs in burn injury classification and material parameter extraction.

Arbab's contributions span innovative imaging systems like hyperbolic-elliptical lens pairs for spherical surface imaging and telecentric scanning optics. His instrumentation advances include high-speed THz time-domain spectroscopy (THz-TDS) systems with improved resolution and field-of-view. He explores scattering mitigation techniques using wavelet transforms and Monte Carlo simulations to enhance THz imaging in turbid media.

Recent clinical studies demonstrate the PHASR scanner's efficacy in non-invasive burn depth determination and wound healing prediction. His work bridges fundamental THz physics with practical applications in healthcare and engineering, supported by interdisciplinary collaborations in biomedical engineering and materials science.
