The interest of Sarah Parker, MS, MD, is in understanding the molecular determinants of vascular pathology and using that knowledge to design new diagnostics and treatments for indolent vascular diseases such as aneurysms and atherosclerosis. The Parker lab uses advanced mass spectrometry-based techniques to profile vascular proteomes. The lab then employ various statistical and bioinformatics tools to convert these large datasets into new knowledge, with the goal to advance the translation of our basic discoveries into actionable new clinical tools. Large-scale omics projects produce many new hypotheses, and thus we are also engaged in and equipped for the in vitro, ex vivo, and in vivo validation of novel hypotheses linking molecular events to relevant vascular physiology within cellular and animal models. While they have diverse collaborations, the focus of our current work is on the interplay between the extracellular matrix, vascular integrins, smooth muscle cell metabolism, and aneurysm progression. In another area of focus, they are defining the molecular architecture of normal human aortic and coronary artery vessels and then tracking how this architecture changes with fatty streak and fibrous plaque lesion progression. The end goal is to improve the detection, monitoring, and treatment of the diseases they study.

Many of the physicians who have medical staff privileges to practice medicine at Cedars-Sinai Medical Center are independent physicians, and not employees or agents of the hospital. These independent physicians bill separately for their services. You should contact your physician to determine their status and billing practices.
