Student Research Assistant (Prof. John Howell)
Chapman University Careers•Irvine, CA
About The Position
The undergraduate Student Research Assistant will support a project developing a low-cost, non-invasive optical imaging system to measure subtle facial blood-flow changes associated with concussions and autonomic nervous system dysfunction. The project uses a standard digital camera and remote photoplethysmography (rPPG) to detect small variations in facial skin color caused by changes in blood volume and circulation. The work explores whether inexpensive camera-based measurements can provide objective biomarkers for concussion assessment and recovery monitoring.
Requirements
- Undergraduate student.
- Understanding of programming.
- Strong background in mathematics, especially linear algebra.
Responsibilities
- Help develop Python-based image-processing and signal-analysis algorithms to track blood flow across different facial regions.
- Extract physiological signals, including heart rate and low-frequency vascular oscillations.
- Examine how physiological signals respond to controlled physiological challenges.
- Use facial landmark tracking, spatial mapping, Fourier analysis, and singular value decomposition to identify patterns of vascular activity that may distinguish healthy individuals from patients recovering from concussions.
