I have spent my research career investigating the vascular physiology and pathophysiology of endothelial inflammatory mechanisms cells in tissue injury and their contributions to disease. In recent years, my laboratory has focused on stem cell protection and restitution of tissues against diverse forms of acute ischemic and inflammatory injury using both mouse models of stroke and inflammatory bowel disease and cell models derived from human and mouse tissues as well. The current proposal focuses on mechanisms underlying protection against stroke injury; our lab has a track history of studying forms of central nervous system vascular injury and blood brain barrier including a recent patent on protection against ischemic injury. We have also been funded to work in this area and perform all of the molecular analyses described in the current proposal using stem cells. We also use these stem cells in synthetic tissues and 3D printed models. In these endeavors I have been privileged to act as a mentor for many trainees who are now independent investigators.
Laboratory: Harris Lab
Dr. Randa Eshaq completed her bachelor and master degrees in biomedical engineering from Louisiana Tech University. She got a position as a research associate at LSU Health Shreveport in the biochemistry department and then switched to the molecular and cellular physiology department. Dr. Eshaq completed her PhD in 2019 at LSU health Shreveport and is currently working on her Postdoctoral Fellowship.
Dr. Eshaq's research is focused on changes occurring in the microcirculation due to pathologies such as diabetes and hypertension.
AREA OF SPECIALTY
The retinal microcirculation and endothelial dysfunction due to pathologies such as diabetes and hypertension
Dr. Eshaq is originally from the country of Yemen, and was born in the costal city of Aden. Aden was formed from a dormant volcano, so she can say that she was born on a volcano. In her free time she enjoys drawing and painting, she also likes to cook and share with her friends all the interesting creations she makes.
She also likes to spread the love and understanding of science in the community, so she participates in fundraising for the children's hospital, setting up scientific demos for the public in cooperation with Sciport museum, at the Barksdale Air Force base, and at events such as heart health day and ideas day.
