Leo Hollberg
Professor (Research) of Physics and of Geophysics
BioHow can we make optimal use of quantum systems (atoms, lasers, and electronics) to test fundamental physics principles, enable precision measurements of space-time and when feasible, develop useful devices, sensors, and instruments?
Professor Hollberg’s research objectives include high precision tests of fundamental physics as well as applications of laser physics and technology. This experimental program in laser/atomic physics focuses on high-resolution spectroscopy of laser-cooled and -trapped atoms, non-linear optical coherence effects in atoms, optical frequency combs, optical/microwave atomic clocks, and high sensitivity trace gas detection. Frequently this involves the study of laser noise and methods to circumvent measurement limitations, up to, and beyond, quantum limited optical detection. Technologies and tools utilized include frequency-stabilized lasers and chip-scale atomic devices. Based in the Hansen Experimental Physics Laboratory (HEPL), this research program has strong, synergistic, collaborative connections to the Stanford Center on Position Navigation and Time (SCPNT). Research directions are inspired by experience that deeper understanding of fundamental science is critical and vital in addressing real-world problems, for example in the environment, energy, and navigation. Amazing new technologies and devices enable experiments that test fundamental principles with high precision and sometimes lead to the development of better instruments and sensors. Ultrasensitive optical detection of atoms, monitoring of trace gases, isotopes, and chemicals can impact many fields. Results from well-designed experiments teach us about the “realities” of nature, guide and inform, occasionally produce new discoveries, frequently surprise, and almost always generate new questions and perspectives. -
Marie Hollenhorst, MD, PhD
Member, Maternal & Child Health Research Institute (MCHRI)
BioDr. Hollenhorst is a physician and scientist with expertise in non-malignant hematology, transfusion medicine, and chemical biology. Dr. Hollenhorst values the one-on-one relationships that she forms with her patients, and strives to deliver the highest quality of care for individuals with blood diseases. Her experience caring for patients drives her to ask scientific questions in the laboratory, where she aims to bring a chemical approach to the study of non-malignant blood disease.
Dr. Hollenhorst pursued combined MD and PhD training at Harvard University, where she received a PhD in Chemical Biology under the mentorship of Professor Christopher T Walsh. She subsequently completed a residency in Internal Medicine at Brigham and Women's Hospital, a fellowship in Transfusion Medicine at Harvard Medical School, and a fellowship in Hematology at Stanford.
Dr. Hollenhorst has an interest in the biology of platelets, which are cellular fragments that help the blood to maintain a healthy balance between bleeding and clotting. Working in the laboratory of Professor Carolyn Bertozzi of Stanford Chemistry, Dr. Hollenhorst is studying sugar molecules found on the surface of platelets that are important in controlling their function and lifespan.
Dr. Hollenhorst's research is supported by an NIH K99 Career Pathway to Independence in Blood Science Award for Physician-Scientists, a Stanford Chemistry, Engineering & Medicine for Human Health Physician-Scientist Fellowship, and a National Blood Foundation Early-Career Scientific Research Grant. -

Randall Holmes
Lecturer
BioAfter completing service in the U.S. Army, Dr. Holmes earned his BS in Civil and Environmental Engineering, MS in Earth System Science, and PhD from Stanford's Emmett Interdisciplinary Program in Environment and Resources (E-IPER) focused on sustainable groundwater management in California. As an E-IPER MS Lecturer, Dr. Holmes co-designs and delivers curriculum that bridges theory with practical applications exemplified by the E-IPER MS Capstone Seminar. He creates collaborative learning environments where students develop critical systems-thinking skills through hands-on engagement with complex sustainability challenges. Dr. Holmes' teaching philosophy emphasizes an inclusive, problem-posing education with pedagogical approaches that prepare diverse student populations for both academic success and real-world problem-solving. His interdisciplinary background enables him to connect students with cross-cutting perspectives essential for addressing today's most pressing environmental and resource sustainability issues.

Susan Holmes
Professor of Statistics, Emerita
Current Research and Scholarly InterestsOur lab has been developing tools for the analyses of complex data structures, extending work on multivariate data to structured multitable table that include graphs, networks and trees as well as categorical and continuous measurements.
We created and support the Bioconductor package phyloseq for the analyses of microbial ecology data from the microbiome. We have specialized in developing interactive graphical visualization tools for doing reproducible research in biology. -
Mark Holodniy
Professor of Medicine (Infectious Diseases)
Current Research and Scholarly InterestsMy research program is currently focused in three areas: 1) Translational research (viral evolution and antiviral resistance prevalence and development), 2) Clinical trials (diagnostic assay/medical device, antimicrobials and immunomodulators), and 3) Health services research focusing on public health, infectious diseases and clinical outcomes.

Erin Eanes Holsinger
Lecturer, Health Policy - HP/PCOR
Clinical Assistant Professor, Pediatrics - General PediatricsBioErin Holsinger is a Lecturer in the Department of Health Policy and a Clinical Assistant Professor in the Department of Pediatrics. In Health Policy, she is a co-director of the Health Services and Policy Research Scholarly Concentration in the School of Medicine and the Administrative Director of the Health Policy MS and PhD programs. In Pediatrics, she is an attending physician at the Gardner Packard Children’s Health Clinic. She is a member of Stanford’s LongSHOT (Longitudinal Study of Handgun Ownership and Transfer) team and performs research about the impact of gun ownership on the risk of death for the gun owner and those who live with them.
