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.
Dr. Liu has authored articles in the New England Journal of Medicine, Journal of Immunology, Journal of Allergy and Clinical Immunology in Practice, Clinical and Experimental Allergy, Mucosal Immunology, Diagnostic Microbiology and Infectious Disease, Science, and other publications. Dr. Liu authored the book chapter “Hypersensitivity Reactions to Monoclonal Antibodies” in Drug Allergy Testing.
Dr. Liu is certified in infectious disease by the American Board of Internal Medicine and in allergy and immunology by the American Board of Allergy and Immunology. She is also a member of the American College of Physicians, Infectious Diseases Society of America, and American Academy of Allergy, Asthma, and Immunology.
She has given presentations on antibiotic allergies, drug desensitization, and aspirin-exacerbated respiratory disease, among other topics. Dr. Liu’s honors include recognition from the American Academy of Asthma, Allergy, and Immunology, the American Medical Women’s Association, and the National Institutes of Health. -
Christine Kee Liu
Associate Professor of Medicine (Primary Care and Population Health)
BioDr. Liu and her research program are dedicated to improving the lives of older adults with kidney disease. Currently her research focuses on mobility, which is the ability to move safely and reliably from one place to another. In older adults, poor mobility strongly predicts future disability and death. Retaining mobility has been cited by older adults as fundamental to quality to life; yet many older persons with kidney disease, especially those with late stage chronic kidney disease or outright kidney failure, have trouble just walking across the room or transferring to a chair. Dually trained in geriatric medicine and epidemiology, Dr. Liu also has significant expertise in older adult clinical trials, including safety trials of novel agents as well as intervention studies to reduce infections in older populations.

Lili Liu
Postdoctoral Scholar, Epidemiology
BioLili (Larry) Liu, PhD, is a postdoctoral fellow in the Department of Epidemiology and Population Health at Stanford University. Dr. Liu is an integrative epidemiologist whose research is unified by a consistent methodological approach rather than a single disease area. Across his master’s, doctoral, and postdoctoral training, he has repeatedly developed or operationalized epidemiologic frameworks and analytic programs and applied them to important public health questions spanning rare diseases, chronic disease, cancer, mortality, microbiome, and women’s health. His work brings together molecular biomarkers, large-scale population cohorts, and real-world health data to generate coherent, hypothesis-driven research on how genetic variation, lifestyle, pharmacologic factors, and early-life exposures shape inflammation, biological aging, and chronic disease risk across the life course.
During his master’s training at Peking University, Dr. Liu developed expertise in literature synthesis, national claims-based study, rare disease burden estimation, patient-centered health information research, cohort-based analysis, and vaccine effectiveness evaluation. He helped build and apply claims-based analytic algorithms to estimate incidence and prevalence for multiple rare diseases in China, led first-author studies on online health information and patient information needs in rare disease populations, and established an analytic framework for CHARLS-based cohort studies that supported multiple downstream projects. During his PhD training at Vanderbilt University, he expanded into population genetics, molecular and cancer epidemiology, mortality and health disparities research, gut microbiome, and pooled multi-study analyses. His doctoral work included a multi-ancestry GWAS of urinary prostaglandin E2 metabolite (PGE-M), development of PGE-M-derived dietary and lifestyle scores, and Mendelian randomization analyses linking lipid-related pathways to colorectal cancer risk. He also led several first-author studies in the Southern Community Cohort Study on poverty, sitting time, physical activity, walking and mortality, and alcohol intake and the gut microbiome, several of which received substantial public health and media attention.
At Stanford, Dr. Liu has developed an independent research program centered on women’s health and life-course epidemiology using U.S. national claims data. He has built large nationwide pregnancy and mother-baby cohorts from MarketScan to study adverse obstetric outcomes, long-term cardiometabolic and hepatic outcomes, and early-onset cancer risk. His first corresponding-author paper at Stanford examined gestational diabetes in relation to subsequent type 2 diabetes and metabolic dysfunction-associated steatotic liver disease, and his ongoing work extends this framework to cardiovascular, kidney, metabolic, and reproductive health outcomes, including PCOS and endometriosis. He also received a Stanford MCHRI fellowship grant to study prenatal and early-life antibiotic exposure in relation to pediatric inflammatory bowel disease and celiac disease. In parallel, his collaborative work includes placental and maternal-fetal research on extracellular vesicles and angiogenic signaling.
Methodologically, Dr. Liu works at the interface of causal inference, pharmacoepidemiology, molecular epidemiology, and scalable real-world data science, using reproducible analytic pipelines in R, Python, SQL, and high-performance computing environments. Across all stages of his training, the central theme of his work has been to build scalable analytic infrastructure and apply it to high-impact epidemiologic questions with broad public health relevance, with the overarching goal of translating rigorous population science into actionable strategies for chronic disease prevention in diverse populations. -
