Sean Paul Spencer, MD,PhD
Assistant Professor of Medicine (Gastroenterology and Hepatology)
BioSean Spencer, MD,PhD is a Gastroenterologist and Physician Scientist at Stanford University working to uncover the role of dietary intake on the gut microbiome and mucosal immune system. Sean obtained his medical degree University of Pennsylvania, earning his PhD studying nutritional immunology with Yasmine Belkaid,PhD at the National Institutes of Health (NIH), after which he moved to Boston for residency training at Massachusetts General Hospital and completed his Gastroenterology training at Stanford University. Sean’s career goal is to study mechanisms by which dietary intake influences our microbiome and immune system to better understand and treat gastrointestinal disease. Sean has launched a microbiome-focused clinical practice at Stanford where he is working to develop novel microbiome diagnostics and microbial medicines.

Adam Sperling, MD, PhD
Assistant Professor of Medicine (Hematology)
BioDr. Sperling received his medical degree and PhD in Biological Chemistry from the University of California, Los Angeles in 2011. He completed his residency in internal medicine at the Brigham and Women's Hospital and his fellowship in Hematology and Oncology at the Dana-Farber Cancer Institute. He received board certification from the American Board of Internal Medicine in 2014, in Medical Oncology in 2017 and in Hematology in 2018. He was a member of the staff at the Dana-Farber Cancer Institute and the Brigham and Women's Hospital in Boston from 2018-2026, where he was an Assistant Professor of Medicine at Harvard Medical School. He joined the faculty at Stanford University in 2026, where he is a hematologist and basic and translational researcher in hematologic malignancies. He cares for patients with multiple myeloma and related blood cancers and his research focuses on understanding the mechanisms of disease evolution from pre-malignant conditions and the development of drug resistance in multiple myeloma and other hematologic malignancies.

Erik Sperling
Associate Professor of Earth and Planetary Sciences, Senior Fellow at the Woods Institute for the Environment and Associate Professor, by courtesy, of Oceans
Current Research and Scholarly InterestsThe research interests in the Sperling Lab are Earth history and the evolution of life, and the interactions between the biosphere and the geosphere. As such this research can generally be considered paleontology, insofar as paleontology encompasses all aspects of the history of life.
Consequently, we define our research agenda by the questions we are interested in, rather than the tools used. This research incorporates multiple lines of evidence, and multiple tools, to investigate questions in the history of life. These lines of evidence include fossil data, molecular phylogenetics, sedimentary geochemistry, and developmental and ecological data from modern organisms. Ultimately, the goal is to link environmental change with organismal and ecological response through the lens of physiology.
Our field research takes place all over the world--current areas include:
-NW Canada (Yukon and Northwest Territories): Research has been conducted on the early Neoproterozoic Fifteenmile Group, Cryogenian and Ediacaran Windermere Supergroup, and on the Ordovician-Devonian Road River Group in the southern Richardson Mountains
-Southern Canadian Cordillera: Work here has focused on the early Cambrian Mural Formation and its soft-bodied fauna.
-England and Wales: Cambrian-Silurian successions in the Welsh Basin
-Namibia: Ediacaran Nama Group
-Upwelling zones: We study the oxygen minimum zone offshore California as an analogue for ancient low-oxygen oceans. -

Daniel Spielman
Professor of Radiology (Radiological Sciences Lab) and, by courtesy, of Electrical Engineering
Current Research and Scholarly InterestsMy research interests are in the field of medical imaging, particularly magnetic resonance imaging and in vivo spectroscopy. Current projects include MRI and MRS at high magnetic fields and metabolic imaging using hyperpolarized 13C-labeled MRS.

Joshua M. Spin
Clinical Associate Professor, Medicine - Cardiovascular Medicine
Current Research and Scholarly InterestsDr. Spin began his research career studying the structural biology of low density lipoprotein, and has had intensive training in molecular biology techniques, particularly high-throughput genetic expression profiling. He is especially interested in vascular smooth muscle cells, and the role of smooth muscle differentiation and phenotypic switching in development, and in vascular disease. His latest work has focused on the biology of aortic aneurysms.
