Daniel Yuhang Li
Instructor, Medicine - Cardiovascular Medicine
BioI am a physician scientist in the Division of Cardiology at Stanford. My clinical interest is at the intersection of inflammation, autoimmunity and cardiovascular disease in a field called 'Cardio-Rheumatology'. Patients with rheumatologic diseases typically have an elevated cardiovascular disease risk profile along with an insidious onset. Moreover, with the ever-expanding biologic drug formulary for patients, it is important for us to characterize the cardiovascular effects of these medications. In my research, I believe that understanding how inflammatory and autoimmune mechanisms modify coronary artery disease can help us develop a novel perspective towards treating atherosclerosis beyond lipid lowering. My research goal is to advance novel therapeutics for atherosclerosis by leveraging my expertise in genetics, computational biology, and experience with diverse model organism perturbation models. My strategy employs a ‘systems’ approach, starting with human population variations at the genetic level and integrating findings across RNA, protein, and model organism studies. This comprehensive synthesis aims to grasp the overarching biological narrative, thereby facilitating the development of translational therapies that transform concepts from bench to bedside.

Ronglih Liao
Douglass M. and Nola Leishman Professor of Cardiovascular Disease
BioDr. Liao is a Professor of Medicine and co-Director of Stanford Cardiac Amyloid Center. The major goal of her research program focuses on understanding the mechanisms that underlie the pathophysiology of heart failure and developing novel treatments to combat this process. Her laboratory has played an international leading role in the study of amyloid light chain (AL) cardiomyopathy, a rare and fatal form of cardiovascular disease. We have described the underlying pathophysiologic basis for amyloid cardiomyopathy and found that the circulating amyloidogenic light chain proteins that characterize this disease directly result in a specific cardiotoxic response. Consequently, our research work has redefined AL cardiomyopathy and has raised new treatment approaches. More recently, her research efforts have expanded to include transthyretin (ATTR) cardiac amyloidosis.
In line with her goal of revealing novel therapeutic strategies for patients with cardiovascular disease, our efforts have also focused on characterizing and harnessing endogenous cardiac regenerative mechanisms. Her laboratory initially demonstrated the therapeutic potential of exogenous primitive muscle cells delivered to the injured heart. This work was among the earliest milestones in the field and served as the basis for an international trial of cell-based therapy. Subsequently, Liao lab identified and characterized a population of cardiac progenitor cells and its relationship and dynamic activity following cardiac injury in the adult heart. Her laboratory aims to reveal the molecular mechanisms regulating the endogenous regenerative capacity of the heart and to harness such repair mechanisms for the treatment of cardiovascular disease. Dr. Liao has lectured extensively on both amyloid cardiomyopathy and stem cell biology, and have maintained a history of independent NIH funding in these areas for more than two decades.
Over the course of her academic career, she has taken the greatest pride in mentoring the next generation of scientists. Dr. Liao has had the privilege to supervise several dozen students, postdoctoral fellows, and junior faculty, many of whom have gone on to independent academic careers at the highest institutions. Her contribution to the advancement of scientific knowledge also includes lecturing at various university and academic institutions as well as at scores of conferences and symposia locally, nationally, and internationally. -

Anne Liu
Clinical Professor, Pediatrics - Immunology
Clinical Associate Professor (By courtesy), Medicine - Pulmonary, Allergy & Critical Care MedicineBioDr. Liu is a board-certified, fellowship-trained specialist in allergy/immunology and infectious disease. She is also a clinical associate professor in the Department of Medicine, Division of Infectious Diseases and the Department of Pediatrics, Division of Allergy, Immunology, and Rheumatology at Stanford University School of Medicine.
Dr. Liu treats infections in patients with compromised immune systems, whether due to a primary immune deficiency or a condition like cancer or organ transplant. She helps patients to develop tolerance to medications they are allergic to so that they can receive the best, and sometimes the only, treatments available to them. She also treats allergies to antibiotics, aspirin, NSAIDs, chemotherapy, and more. She sees patients both long term and for urgent referrals, such as in cases of perioperative anaphylaxis. Dr. Liu also helps pediatric patients manage drug and food allergies.
One of Dr. Liu’s areas of focus is helping patients with allergies to antibiotics determine when they have lost an allergy, what antibiotics they can tolerate, and when to induce tolerance to an antibiotic. This not only can benefit the patient, but also have a positive public health impact, as labeling patients with a penicillin allergy may negatively affect their care and increase use
of broad-spectrum antibiotics.
She collaborates closely with colleagues from other disciplines, including pulmonology, otolaryngology, oncology, cardiology, dermatology, anesthesiology, and surgery. Her key objective in working with referring physicians is to help them safely deliver the best care for their patients.
For patients and families, Dr. Liu strives to help them navigate their care journey with as much ease and dignity as possible during what may be the most challenging time of their life. Her goal is to offer patients options, even when it may appear that they have no options left.
Dr. Liu’s research interests include optimizing care of patients with antibiotic allergies, including through use of decision support tools.

Eric Meffre
Professor of Medicine (Immunology and Rheumatology)
BioDr. Meffre obtained his PhD in Immunology from the Université d’Aix-Marseille in France before he moved to the USA as a postdoc fellow in the laboratory of Dr. Michel Nussenzweig at The Rockefeller University in New York City. He became an assistant professor at Cornell University in 2003 before being recruited at Yale University as associate professor in 2009. He was tenured at Yale in 2014 before he joined the Department of Medicine/Division of Immunology and Rheumatology at Stanford University as a tenured full professor in 2022.
Dr. Meffre’s work focuses on the etiology of autoimmune syndromes and the roles played by B cells in these diseases. His group characterized the abnormal selection of developing autoreactive B cells in patients with rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), type 1 diabetes (T1D), multiple sclerosis (MS) and Sjögren’s syndrome, resulting in large numbers of autoreactive naïve B cells accumulating in the patient’s blood. Hence, these autoreactive B cells may present self-antigens to T cells and initiate autoimmune diseases. These early B cell tolerance defects are likely primary to these autoimmune diseases and may result from genetic factors such as the 1858T PTPN22 allele that segregates with RA, SLE and T1D and correlate with an impaired removal of developing autoreactive B cells.
His research goals also consist in characterizing the molecules and pathways involved in the establishment of B cell tolerance and the removal of developing autoreactive B cells generated by random V(D)J recombination through the investigation of rare patients with primary immunodeficiency (PID) enrolled through an international network. Alteration of B cell receptor (BCR) or Toll-like receptor (TLR) signaling in PID patients results in a defective central B cell tolerance and a failure to counterselect developing autoreactive B cells in the bone marrow. In contrast, functional and suppressive regulatory T cells play a key role in preventing the accumulation of autoreactive clones in the mature naïve B cell compartment. The recent development of humanized mouse models recapitulating early B cell tolerance checkpoints and their defects in autoimmune settings allow further in-depth investigation of tolerance mechanisms and the development of novel approaches to restore defective central and peripheral B cell tolerance checkpoints and thwart autoimmunity. -
