Research Interests

My research interests are mainly in the areas of cerebrovascular diseases and diabetes, specifically in developing novel predictive and therapeutic avenues for hemorrhagic stroke and vascular complications of diabetes. My ongoing research topics include:

  1. Endothelial progenitor cells (EPCs) in vascular protection and tissue repair.
  2. Extracellular microvesicles (MVs) in vascular diseases.

EPC priming for functional enhancement with angiotensin converting enzyme (ACE2) and CXCR4 have been studied in my research. The effects of cardiovascular risk factors on the release and cargoes (proteins and microRNAs) of EPC-MVs are currently under investigation. The functional role of EPC-MVs on endothelial cells (ECs), smooth muscle cells (SMCs), and neuronal and glial cells are also currently being explored.

The approaches applied in my laboratory include molecular, cellular and integrative methodologies. These methods include west blot, real-time PCR, mass spectrum, microRNA sequencing, Yeast-two-Hybrid (Y2H), nanosight tracking analysis (NTA), flow cytometry, etc. Animal surgery methods (telemetric probe, osmotic minipump, microinjection) are also used in my research. The animal models used in my research include a spontaneous hemorrhagic stroke model induced in the rennin/angiotensinogen double transgenic (R+A+) hypertensive mice, collagenase-induced focal hemorrhagic stroke model and the db/db diabetic mouse model. Additionally, I use clinical samples from translational studies of diabetes and stoke patients through collaboration with clinicians.
