RESEARCH EXPERIENCE:

2006 - Present: Research Associate, Cardiovascular Research Lab

Rutgers University, New Brunswick, New Jersey

 Developing Near Infrared Spectroscopy (NIRS) acquisition system applied to cerebrospinal oxygenation measurement in spinal cord injuries, including device design, data acquisition computer application and animal experiment.

 Modeling arterial system with distributed transmission line theory and fluid dynamics with clinical applications.

 Developing medical wireless data acquisition.

 Managing and maintaining the Cardiovascular Research Lab

2004-2006: Dissertation Study, Cardiovascular Research Lab, Rutgers University, NJ

 Developed distributed arterial computation model that simulates blood pressure propagation in the entire arterial system. The modeling was based upon electric transmission line theory in frequency domain and Womersley’s solution to Navier-Stokes’s equations.

2002 – 2005: Graduate Research Assistant, Cardiovascular research lab

Rutgers University, New Brunswick, New Jersey

 Designed wireless device to transmit and receive ECG, blood pressure and flow, and heart sound; vascular stiffness study with wireless monitoring blood pressure and flow.

 Studied vascular wall property with pulse wave velocity: designed non-invasive and continuous blood pressure monitor – arterial tonometer; multi-artery pulse wave velocity study under resting and exercise conditions.

 Cardiac output study: designed cardiac impedance device and studied transient changes in cardiac output for different postures.

1995-1999: Graduate Research assistant, Flow Research Labs, Tianjin University, China

 Participated in the Nation Science Foundation sponsored electric resistance tomography project for the two-phase flow measurement and responsible for designing the real-time imaging system.

 Designed micro-controller based intelligent flow transducers and computers. Participated in the full-term development and manufacture of families of flow computers.

TEACHING EXPERIENCE

2003-Present: Senior Design Mentor, Biomedical Engineering, Rutgers University, NJ

2002-2006: Graduate Teaching Assistant, Rutgers University, New Brunswick, NJ

 Systems Physiology Lab course (2002-2006). Performed surgical procedures and cardiovascular and pharmacological study in rats.

 Biomedical Instrument Lab course (2002-2006).
