Current Research

  • Flow-induced blood damage by mechanical heart valves

Abnormal blood flow patterns associated with mechanical heart valves (MHVs) play an important role in triggering blood cell damage. Patients with MHVs have an increased risk of blood clotting and need lifetime anticoagulant therapy. I hypothesize that the non-physiological performance of MHVs is responsible for prolonged exposure of blood cells to elevated shear stresses, which may induce cell damage. At National University of Ireland, Galway, I combined a scaled-up experimental model of MHV flow with a Particle Image Velocimetry (PIV) to obtain flow measurements at unprecedented resolution. As a result, I was able to use Lagrangian tracking methods to calculate trajectories, mechanical loading and damage indices of platelets traveling through the MHV. With my research, I demonstrated that abnormal shear stresses in the flow downstream of MHVs can reduce the lifespan of blood cells and trigger platelet activation and clotting. At SJSU, I have worked with graduate students to develop a physiological-scale mock circulation loop to test the hemodynamic performance of trileaflet MHVs, a novel design approach that may mimic more closely the dynamics of natural valves. I am currently seeking funding from NSF to acquire a time-resolved PIV system to further investigate the performance of trileaflet valves.

  • Right ventricular-pulmonary vascular interactions in pulmonary hypertension

My research aims at understanding the mechanisms of progression of pulmonary arterial hypertension (PAH) using data obtained from large animal studies and clinical trials. PAH originates in the distal pulmonary vasculature and ultimately leads to right ventricular failure. Despite modern therapies, PAH remains a progressive and fatal disease. My overall hypothesis is that stiffening of the pulmonary arteries, caused by PAH, impairs right ventricular function by decreasing the efficiency of ventricular-vascular interactions. Through extensive collaboration with UW-Madison, Northwestern University, and the Golden Jubilee National Hospital (Glasgow, UK) I have demonstrated the effect of exercise on ventricular-vascular function and contributed to shed light on the prognostic value of medical image analysis in PAH.

  • Wearable devices for monitoring heart function

Recently, I have developed an active interest in wearable biosensor technology, and its tremendous potential to improve cardiovascular disease management. Wearable biosensors have experienced a tumultuous growth over the past few years, mostly driven by the consumer market. The technological advancement in biosensor technology and wireless communication has been impressive. Potential applications of continuous wireless tracking of heart function include (1) monitoring of mental stress and learning efforts in college students, (2) continuous and accurate monitoring of cardiovascular parameters in patients with heart-related conditions, (3) continuous tracking of energy expenditure in hospitalized patients to assess the effectiveness of rehabilitation strategies. My interest has resulted in a number of ongoing explorative projects, developed with undergraduate and graduate students in the Biomedical Engineering program at SJSU and financially supported by the College of Engineering via the two Centers of Excellence recently launched, as well as an ongoing collaboration with a local startup company focused on wearable technology.
