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. -

Tobias Lanz
Assistant Professor of Medicine (Immunology and Rheumatology)
BioTobias Lanz, MD is an Assistant Professor at the Institute for Immunity, Transplantation, and Infection and the Division of Immunology and Rheumatology at Stanford. His research focuses on B cell biology in neuroimmunological diseases and rheumatic diseases with neurological manifestations. He uses high-throughput screening technologies, and methods from structural and cell biology to identify new autoantigens and to understand how certain self-reactive B cells escape tolerance mechanisms. He is particularly interested in molecular mechanisms that explain the association between Epstein Barr Virus (EBV) and autoimmunity.
Tobias went to medical school at the Eberhard Karls University in Tübingen, Germany and at the University College of London. He wrote his MD thesis at Dr. Michael Platten's laboratory at the Hertie Institute for Clinical Brain Research in Tübingen, Germany before joining Dr. Lawrence Steinman’s neuroimmunological laboratory at Stanford as a research scholar. After medical school he pursued his scientific and clinical training at the German Cancer Research Center (DKFZ) and the Department of Neurology at the University Hospital in Heidelberg, Germany. In 2015 he joined Dr. William Robinson’s lab at Stanford, where he investigated environmental triggers of autoimmunity, including viruses and milk consumption. In his most recent work, he characterized the B cell repertoire in the spinal fluid of patients with multiple sclerosis (MS) and identified molecular mimicry between EBV EBNA1 and the glial cellular adhesion molecule GlialCAM as a driver of neuroinflammation (Lanz et al., Nature, 2022). His long term objective is to leverage these newly discovered mechanistic insights to develop next-generation biomarkers and therapeutics for autoimmune diseases. -

Amira Latif Hernandez
Instructor, Adult Neurology
BioAmira obtained her Ph.D. in Neuroscience from the KU Leuven, Belgium, in summer 2017. During her doctoral studies, she used clinically valid tests of murine cognition, neuronal plasticity measures in hippocampal and cortical slices, brain lesion methods, pharmacological applications and resting state functional magnetic resonance imaging to characterize the pathophysiology of novel mouse models of Alzheimer’s disease (AD). One of her most gratifying contributions was the development of a new electrophysiology tool to assess synaptopathies, and the establishment of long-term synaptic plasticity from prefrontal cortex of APP knock-in mice. In Autumn 2017, she moved to Dr. Longo’s lab at the Stanford School of Medicine, where she investigates signaling pathways involved in synaptic degeneration. During 3 years of postdoctoral work, she established a multi-electrode array system with eight independent recording chambers that allows high-throughput analyses of multiple long-lasting forms of synaptic plasticity. She also gained experience in RNA-sequencing, molecular biochemistry, signaling mechanisms, target validation and drug development strategies for AD. In October 2020, Amira has been appointed as an Instructor in Neurodegenerative Disease Research, in the Longo lab, to help develop improved and more powerful approaches that will better reveal key synaptic mechanisms and candidate modules associated with neuroplasticity and affected in AD mouse models, by identifying activity-dependent gene expression signatures.

BioMy current research focuses neurodegenerative and ocular diseases, with an added focus on the unfolded protein response, specifically the PERK pathway. Through my work, I investigate the cellular mechanisms underlying diseases like Alzheimer's and advanced tauopathies, with an emphasis on endoplasmic reticulum (ER) stress.
As I continue to deepen my understanding of disease pathology, I am also pursuing a residency in pathology (ECFMG-Certified, AAMC: 14765627), with a current interest in neuropathology and forensic pathology. Alongside my primary research, I have been involved in a forensic unidentified persons project, applying my skills from my previous graduate studies in forensic science and extensive autopsy experience. Here I further explore my passion for understanding disease processes and the human body through both clinical and investigative perspectives, fueled by empathy and compassion.
Additionally, I volunteer as a crisis counselor and enjoy activities such as traveling and learning languages, Toastmasters, and escape rooms. -
Quynh-Thu Le, MD, FACR, FASTRO, FARS
Katharine Dexter McCormick and Stanley McCormick Memorial Professor and Professor, by courtesy, of Otolaryngology - Head & Neck Surgery (OHNS)
Current Research and Scholarly InterestsMy laboratory focuses on identifying pathways and biomarkers of treatment resistance in head and neck cancer using clinical samples. We explore approaches to modulate these pathways through preclinical models (cell lines, organoids, tumor bearing mice) in order to develop precise strategies against these resistant mechanisms.
