Parker Lab
Research in the Parker Lab harnesses the power of proteomic technologies to elucidate mechanisms of vascular pathology and identify putative molecular biomarkers of aneurysm and atherosclerosis.
Aneurysm is an "invisible" condition, often undetected until severe and catastrophic dissection or rupture have occurred. Surgery remains the only treatment for aneurysm but knowing when to intervene surgically for a given patient remains a clinical challenge. Our research is focused on identifying molecular signatures of aneurysm that inform both potential pharmacological treatments to slow aneurysm progression as well as potential circulating biomarkers for both the detection and therapeutic management of aneurysms.
We develop and employ a wide range of technologies, from simple vascular physiology experiments to cutting edge mass spectrometry based proteomic and metabolomic techniques.
While our direct focus is on aneurysms and their consequences, we also apply the power of proteomics to diverse collaborations studying atherosclerosis, fibrosis, ovarian cancer and autoimmune disease.
The Parker Laboratory is affiliated with the Department of Cardiology, Smidt Heart Institute, Advanced Clinical Biosystems Research Institute, Proteomics and Metabolomics Core, and Department of Biomedical Sciences.
Personal Statement
I have seen firsthand the power of hypothesis-generating 'omic techniques to provide novel insight into pathology. As a classically trained physiologist, I also believe firmly in the power of hypothesis-driven research, and the careful confirmation and validation of observations produced during discovery experiments. I have over a decade of experience in mass spectrometry, bioinformatics and cardiovascular physiology that I am applying with a passion in order to positively impact clinical management and therapeutic options available for patients with vascular disease.
