  • Stephen Chang, MD, PhD

    Stephen Chang, MD, PhD

    Instructor, Biochemistry
    Instructor, Medicine - Cardiovascular Medicine

    BioPrior to a career in medicine, Dr. Chang was an English major and subsequent novelist at night. During the days, he taught literature part-time at Rutgers University, and for extra money, worked in a laboratory in NYC washing test tubes. Inspired by his laboratory mentor, he began volunteering at the hospital next door, and developed a love for interacting with patients. Through this experience, he saw how caring for others could form deep bonds between people - even strangers - and connect us in a way that brings grandeur to ordinary life.

    In addition to seeing patients, Dr. Chang is a physician-scientist devoted to advancing the field of cardiovascular medicine. His research has been focused on identifying a new genetic organism that better models human heart disease than the mouse. For this purpose, he has been studying the mouse lemur, the smallest non-human primate, performing cardiovascular phenotyping (vital signs, ECG, echocardiogram) on lemurs both in-bred (in France) and in the wild (in Madagascar) to try to identify mutant cardiac traits that may be heritable - and in the process, characterize the first high-throughput primate model of human cardiac disease.

  • Paul Cheng MD PhD

    Paul Cheng MD PhD

    Assistant Professor of Medicine (Cardiovascular Medicine)

    BioDr. Cheng is a Cardiologist at Stanford University School of Medicine in the Department of Medicine and a member of the Cardiovascular Research Institute. Dr. Cheng received his BEng in Chemical Engineering and BSc in biology at MIT. He subsequently completed his MD/PhD at UCSF working in the Srivastava lab studying how extracellular morphogenic signals affect cardiac development and fate determination of cardiac progenitors. Dr. Cheng completed internal medicine residency and cardiology fellowship at Stanford, including a post-doctoral training in the Quertermous lab. His current clinical focus is in amyloidosis and cardio-oncology.

    Dr. Cheng pioneered the application of single cell transcriptomic and epigenetic techniques to study human vascular diseases including atherosclerosis and aneurysm, and applied these techniques to investigate molecular mechanisms behind genetic risk factors for several human vascular diseases including atherosclerosis, and aortopathies such as Marfan's and Loey-Dietz syndrome. The Cheng lab takes a patient-to-bench-to-bedside approach to science. The lab focuses on elucidating new pathogenic mechanisms of human vascular diseases through combing human genetics and primary vascular disease tissues, with high-resolution transcriptomic and epigenetic profiling to generate novel hypothesis that are then tested in a variety of in vitro and in vivo models. The lab is focused on two broad questions: (1) understanding the biological underpinning of the differences in diseases propensities of different arterial segments in an individual (i.e. why do you have atherosclerosis and aneurysms in certain segments but not others), and (2) understanding the role of perivascular fibroblast in human vascular diseases.

  • Gentaro Ikeda

    Gentaro Ikeda

    Instructor, Medicine - Cardiovascular Medicine

    BioDr. Ikeda is a physician-scientist who develops innovative diagnostic and therapeutic modalities for patients with cardiovascular disease. Based on his clinical experience as a cardiologist, he has become aware of major clinical shortcomings, specifically in the current pharmaceutical therapies for myocardial infarction (MI) and chronic heart failure (HF). Some evidence-based drug therapies, including β-blockers, ivabradine, and renin-angiotensin-aldosterone antagonists are difficult to apply to critical patients due to adverse side effects. Drugs that have shown efficacy in basic animal experiments have failed to show significant benefits in clinical trials. To address these problems, he moved to academia to conduct translational research. During his graduate training in the Egashira Lab, he focused on drug delivery systems (DDS) that target mitochondria in animal models of MI. He obtained advanced skills in molecular biology, mitochondrial bioenergetics, and animal surgery. He realized the importance of translational research and the great potential of DDS to overcome many clinical problems. He developed nanoparticle-mediated DDS containing cyclosporine for the treatment of patients with MI. He published a first-author paper and received academic awards for his novel science. Since becoming a postdoctoral fellow in the Yang Lab, he has continued to build upon his previous training in translational research. He is currently developing an innovative therapy, namely, extracellular vesicles-mediated mitochondrial transfer for mitochondria-related diseases such as heart failure and mitochondrial disease.

  • Juyong Brian Kim

    Juyong Brian Kim

    Assistant Professor of Medicine (Cardiovascular Medicine)

    Current Research and Scholarly InterestsThe lifetime risk of developing cardiovascular disease (CVD) is determined by the genetic makeup and exposure to modifiable risk factors. The Cardiovascular Link to Environmental ActioN (CLEAN) Lab is interested in understanding how various environmental pollutants (eg. tobacco, e-cigarettes, air pollution and wildfire) interact with genes to affect the transcriptome, epigenome, and eventually disease phenotype of CVD. The current focus is to investigate how different toxic exposures can adversely remodel the vascular wall leading to increased cardiac events. We intersect human genomic discoveries with animal models of disease, in-vitro and in-vivo systems of exposure, single-cell sequencing technologies to solve these questions. Additionally, we collaborate with various members of the Stanford community to develop biomarkers that will aid with detection and prognosis of CVD. We are passionate about the need to reduce the environmental effects on health through strong advocacy and outreach.
