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. -
Derek Holliday
Postdoctoral Scholar, Political Science
BioDerek Holliday is a Postdoctoral Fellow for the Polarization Research Lab, a cross-university lab between Stanford, Dartmouth, and UPenn researching affective polarization, social trust, and political violence. His work with the lab has been published in the Proceedings of the National Academy of Sciences. His research focuses on political representation, opinion, and behavior, especially in state and local politics. His methodological interests include survey experiments, text-as-data, and applications of machine learning in social science.
Derek received his PhD in Political Science in 2023 from UCLA, where he jointly obtained an MS in Statistics. At UCLA, he was the project coordinator for Nationscape, a U.S. election survey that interviewed almost half a million respondents through the 2020 Presidential campaign. Additionally, he worked as a research analyst for the UCLA COVID-19 Health and Politics Project, a collaboration between social scientists and doctors measuring people’s pandemic experiences and attitudes. Work from the project has been featured in the New York Times and published in Vaccine. -

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.
