Primary Academic Title
Associate Professor of Medicine
Background
Dr. Marlene Stephanie Williams is an Associate professor at the Johns Hopkins University School of Medicine. Her research focuses on coronary atherosclerosis and platelet function, and her particular focus is on platelet function as it relates to the acute coronary syndrome.
Dr. Williams has examined platelet function and its correlation to platelet functional genomics and runs a platelet physiology laboratory on the Johns Hopkins Bayview campus. The goal for her cardiovascular platelet laboratory has been to identify the etiology of platelet dysfunction in many disease states and apply methods that may improve this dysfunction that may eventually be translated to therapies for patients with cardiovascular disease. She is a prior recipient of an NIH career mentored award (K23) examining platelet functional genomics and an NIH RO1 award addressing platelet serotonin signaling in depression and heart disease. Dr. Williams has several publications covering platelet functional changes in settings of interventional cardiology, acute coronary syndrome, and heart disease and depression. She has participated in several NHLBI advisory committees, review groups, and study sections.
Dr. Williams has been the Course Director, of the advanced clinical clerkship in coronary intensive care at the Bayview Medical center and has mentored many medical residents and cardiology fellows.
Dr. Williams received her undergraduate degree in biochemistry from McGill University. She earned a medical degree from the Columbia University College of Physicians & Surgeons and completed a residency at Johns Hopkins Hospital. After completing a residency, Dr. Williams was a cardiology fellow at Mount Sinai Hospital and Johns Hopkins Hospital.
Dr. Williams is currently the Clinical Director of Cardiology at Johns Hopkins Bayview Medical Center.

Platelet Physiology Research Lab
- Dr. Williams' research focuses on platelet physiology particularly as it relates to acute coronary syndromes and depression. Her laboratory specifically examines platelet aggregation, flow cytometric analysis to measure platelet activation, platelet luminescence as a measure of the platelet release reaction, many Elisa preparations in order to measure platelet function, platelet genotyping to determine the presence of certain platelet polymorphisms, and various other assays to distinguish mechanisms of platelet dysfunction. The goal for her cardiovascular platelet laboratory is to identify the etiology of platelet dysfunction in many disease states and apply methods that may improve this dysfunction that can eventually be translated to therapies for patients with cardiovascular disease. Scientific techniques performed in the lab include: flow cytometric analysis, platelet microparticle identification, and protein immunoprecipitation among other techniques.
Research Summary
Research interests lie with coronary atherosclerosis and platelet function. The particular focus is on platelet function as it relates to the acute coronary syndrome.
