Thomas Quertermous

TQ is currently the William G. Irwin Professor of Medicine and Director of the Research in the Division of Cardiovascular Medicine at Stanford University. He completed clinical training in cardiology at the Massachusetts General Hospital and research training in molecular genetics in the Department of Genetics at the Harvard Medical School. Dr. Quertermous established an independent laboratory in the Cardiac Unit at the Mass General in 1987. He was recruited to Vanderbilt University in 1991 as Chief of Cardiology and Professor of Medicine and Molecular Physiology and Biophysics. Dr. Quertermous moved to Stanford University in 1997 where he assumed leadership of the Division of Cardiovascular Medicine. Research in the Quertermous laboratory has employed genetic approaches for the study of vascular disease as a primary focus. Currently, research studies employ large-scale human genetics efforts to better understand the genetic basis of atherosclerosis and related risk factors such as hypertension and insulin resistance. Ongoing efforts include genome-wide association studies in multiethnic cohorts with coronary heart disease, and these efforts are integrated with other worldwide efforts aimed at conducting definitive association based analyses. Variation identified through these studies is further investigated at the molecular level to better understand the basic mechanisms of atherosclerotic heart disease.

Markus Otto Hjalmar Ramste

Markus Otto Hjalmar Ramste is a postdoctoral fellow in the Division of Cardiovascular Medicine in the laboratory of Dr. Thomas Quertermous. He is a physician-scientist by training and a cardiology fellow at the Helsinki University Hospital in Finland. He received his M.D. from Lugwig-Maximilians University in Munich, Germany (2016) and PhD from the University of Helsinki (2019), where he studied vascular growth factors, especially VEGF-B, in the heart under the guidance of academician, Dr. Kari Alitalo. He has a strong background in vascular biology and in vivo-studies and is additionally actively involved in clinical research projects addressing the pharmacogenetics and epidemiology of coronary artery disease.

His research interest is focused, foremost, on the disease entity of coronary artery disease, aiming at a deep understanding of the disease. He aims to achieve this through both preclinical and clinical studies focusing on the diagnostics, genetics and mechanisms of coronary artery disease.

Matthew Worssam

Matt Worssam is a postdoctoral fellow in the lab of Dr. Quertermous at Stanford’s Division of Cardiovascular Medicine and has been awarded a fellowship on the Cardiovascular Institute’s “Mechanisms and Innovations in Cardiovascular Disease” T32 grant program. Matt earned his PhD in the lab of Dr. Helle Jørgensen at the University of Cambridge, where he studied the cellular and molecular mechanisms underlying the clonal contribution of vascular smooth muscle cells (VSMCs) to multiple cardiovascular diseases.

Continuing his VSMC research, Matt’s postdoctoral studies are focussed on VSMC-derived cells within the atherosclerotic plaque which display characteristics of bone-forming chondrocytic cells. Highlighting the importance of chondromyocytes for cardiovascular disease progression, a significant proportion of genes associated with cardiovascular disease risk are selectively expressed by these cells. Matt is using a combination of histology, in vitro functional assays, and single-cell genomics technologies to dissect out the molecular mechanisms governing the transition of VSMCs towards the chondromyocyte fate, and to characterise which of aspects of these cells’ phenotypes most significantly contribute to cardiovascular disease risk.
