Vanessa Gulla, MD
Clinical Assistant Professor, Urology
BioDr. Gulla is a board-certified urologist with fellowship training in endourology. She is a clinical assistant professor in the Stanford University School of Medicine Department of Urology.
For each patient, she develops a comprehensive, compassionate care plan customized to individual needs. Her goal is to help each patient achieve the best possible health and quality of life.
Dr. Gulla performs the complete spectrum of diagnostic and treatment procedures for urological conditions. She treats disorders including benign prostatic hyperplasia (BPH), blood in urine, kidney stones, male and female voiding dysfunction, neurogenic bladder, prostate cancer, and over active bladder.
She excels at ureteroscopy and cystoscopy (examination of the bladder and urinary tract with a scope), endourology (minimally invasive treatment of kidney stones), laser therapy, ultrasound-guided diagnosis and treatment, urodynamic testing, and other techniques.
To help advance her field, Dr. Gulla has conducted research. Among the topics she has investigated are voiding cystourethrogram (VCUG) testing in children for bladder and urethral abnormalities and for conditions that can lead to kidney infections.
She has presented her research findings at the national meeting of the American Urologic Association. She also has published papers in the Journal of the American College of Surgeons and elsewhere.
She is a member of the American Urologic Association. -

Marvin Langston
Assistant Professor of Epidemiology and Population Health and, by courtesy, of Urology
BioDr. Marvin Langston is an Assistant Professor of Epidemiology and Population Health. He is a member of the Stanford Cancer Institute and Urologic Cancer Epidemiology Lab. He is an epidemiologist by training who focuses on the fields of benign prostate and pelvic conditions and urological cancers including prostate and kidney cancers.
Prior to Stanford, he served as a Research Scientist in the Division of Research at Kaiser Permanente Northern California. Dr. Langston received his PhD in Epidemiology from the University of Arizona’s College of Public Health followed by postdoctoral training in Cancer Prevention and Control at Washington University in Saint Louis School of Medicine.
His program of research intends to characterize and measure infectious agents, environmental toxicants, and lifestyle factors; to evaluate the role of these factors in urological cancer etiology and outcomes; and to identify populations at high risk of exposure to these factors. So far he has focused this research to address the following questions: 1) What role do sexually transmitted infections and other systemic infections have in prostate damage and ensuing prostate cancer risk? 2) How can we appropriately model and define early life risk factors for urological cancers? 3) Can we harmonize molecular and clinical aspects of urological condition diagnoses to produce well characterized outcomes for biomarker discovery and etiological investigation? He has primarily addressed these questions using a variety of molecular and clinical epidemiology approaches while developing expertise in the cross-cutting theme of cancer health disparities with particular interests in the cancer care experiences of sexual and gender minorities and racial/ethnic minorities.
Dr. Langston has been studying the impact of exogenous factors on prostate specific antigen (PSA) concentration in young men as a marker of prostate damage and inflammation for over a decade. As early life PSA has been found predictive of future prostate cancer mortality, he has now setout to optimize risk-stratified screening for prostate cancer. This promising approach uses men’s baseline PSA values to inform their risk of future aggressive and/or fatal prostate cancer and determine their frequency of further screening. Under this approach, men with high baseline age-specific total PSA levels receive more frequent screening and men with lower levels receive less frequent screening. Dr. Langston was awarded an R01 from NCI to evaluate this approach using historically collected biospecimen. His funded research trajectory to this point also includes four training awards (2-NCI and 2-NIDDK) and several internal grants. Dr. Langston was selected in the inaugural class of the White House Cancer Moonshot Scholars for his work. -
John Leppert
Professor of Urology and, by courtesy, of Nephrology
Current Research and Scholarly InterestsOur research aims to improve the global quality of care for patients with Urologic Cancer with a particular focus on kidney cancer. We are investigating novel proteomic platforms and assays to diagnose kidney cancer and predict response to therapy. We are evaluating the comparative effectiveness of various kidney cancer surgeries and their impact on chronic kidney disease and its downstream effects. We are applying epidemiology, bioinformatics, and health services methods to urologic conditions.

Alan C. Pao
Associate Professor of Medicine (Nephrology) and, by courtesy, of Urology
Current Research and Scholarly InterestsWe are broadly interested in how the kidneys control salt, water, and electrolyte homeostasis in the body. Our disease focus is on kidney stone disease. We use cultured kidney cells, transgenic mice, human plasma/urine samples, and electronic health record data to study the pathogenesis of kidney stone disease. Our therapeutic focus is on the development of small molecule compounds that can be used for kidney stone prevention.
