Susan Vleck
Assistant Director Lab and Bio Safety, Biosafety Officer, EH&S, Environmental Health and Safety (EH&S)
Current Role at StanfordCurrent Role: Assistant Director, Laboratory Chemical and Physical Safety Program, and Manager, Animal Research Occupational Health and Safety Program, Department of Environmental Health and Safety
I have been a part of the Department of Environmental Health and Safety at Stanford University since 2012. My original role was as a Biosafety and Biosecurity Specialist to support the ongoing development and implementation of Stanford's Biosafety and Biosecurity Program and ensure safe practices, understanding, and compliance for work done using infectious agents and recombinant DNA. I was promoted to Senior Biosafety and Biosecurity Specialist in 2017, and became Program Manager for the Animal Research Occupational Health and Safety Program. In 2020, I transitioned to my current role of Assistant Director, Laboratory Chemical and Physical Safety Program.
I lead the ongoing development and implementation of Stanford's Laboratory Chemical and Physical Safety Program, and ensure safe practices, understanding, and compliance for work done in a wide array of research labs. I lead and direct a team of 9 management and professional personnel to oversee a broad spectrum of environmental, health and safety programs of significant scope and complexity, and oversee subordinate managers with large program responsibilities. I define and direct the overall activities of the group, and allocate appropriate staffing and other resources to achieve objectives, including development and direction of related policies.
I also directly oversee the Animal Research Occupational Health & Safety Program, which serves a centralized point of contact for people seeking help relating to animal and EH&S issues. This program helps bring together groups within EH&S, as well as EH&S and other Stanford departments, to address safety and health issues relating to animals. These issues can fall under a wide range of topics, including biosafety, chemical safety, ergonomics, occupational injury & illness, trainings, lab safety, radiation safety, housing requirements, animal allergies, lasers and PPE. This program serves the research community, but also any staff, student or faculty who interacts with or work in proximity to animals on campus.
My overall goal in my role as Assistant Director is to support the Stanford research community in performing innovative and exciting research safely. -

Current Research and Scholarly InterestsUbiquitin signaling: structure, function, and therapeutics
Ubiquitin is a small protein modifier that is ubiquitously produced in the cells and takes part in the regulation of a wide range of cellular activities such as gene transcription and protein turnover. The key to the diversity of the ubiquitin roles in cells is that it is capable of interacting with other cellular proteins either as a single molecule or as different types of chains. Ubiquitin chains are produced through polymerization of ubiquitin molecules via any of their seven internal lysine residues or the N-terminal methionine residue. Covalent interaction of ubiquitin with other proteins is known as ubiquitination which is carried out through an enzymatic cascade composed of the ubiquitin-activating (E1), ubiquitin-conjugating (E2), and ubiquitin ligase (E3) enzymes. The ubiquitin signals are decoded by the ubiquitin-binding domains (UBDs). These domains often specifically recognize and non-covalently bind to the different ubiquitin species, resulting in distinct signaling outcomes.
We apply a combination of the structural (including protein crystallography, small angle x-ray scattering, cryo-electron microscopy (Cryo-EM) etc.), biocomputational and biochemical techniques to study the ubiquitylation and deubiquitination processes, and recognition of the ubiquitin chains by the proteins harboring ubiquitin-binding domains. Current research interests including SARS-COV2 proteases and their interactions with polyubiquitin chains and ubiquitin pathways in host cell responses, with an ultimate goal of providing strategies for effective therapeutics with reduced levels of side effects.
Protein self-assembly processes and applications.
The Surface layers (S-layers) are crystalline protein coats surrounding microbial cells. S-layer proteins (SLPs) regulate their extracellular, self-assembly by crystallizing when exposed to an environmental trigger. We have demonstrated that the Caulobacter crescentus SLP readily crystallizes into sheets both in vivo and in vitro via a calcium-triggered multistep assembly pathway. Observing crystallization using a time course of Cryo-EM imaging has revealed a crystalline intermediate wherein N-terminal nucleation domains exhibit motional dynamics with respect to rigid lattice-forming crystallization domains. Rate enhancement of protein crystallization by a discrete nucleation domain may enable engineering of kinetically controllable self-assembling 2D macromolecular nanomaterials. In particular, this is inspiring designing robust novel platform for nano-scale protein scaffolds for structure-based drug design and nano-bioreactor design for the carbon-cycling enzyme pathway enzymes. Current research focuses on development of nano-scaffolds for high throughput in vitro assays and structure determination of small and flexible proteins and their interaction partners using Cryo-EM, and applying them to cancer and anti-viral therapeutics.
Multiscale imaging and technology developments.
Multimodal, multiscale imaging modalities will be developed and integrated to understand how molecular level events of key enzymes and protein network are connected to cellular and multi-cellular functions through intra-cellular organization and interactions of the key machineries in the cell. Larger scale organization of these proteins will be studied by solution X-ray scattering and Cryo-EM. Their spatio-temporal arrangements in the cell organelles, membranes, and cytosol will be further studied by X-ray fluorescence imaging and correlated with cryoEM and super-resolution optical microscopy. We apply these multiscale integrative imaging approaches to biomedical, and environmental and bioenergy research questions with Stanford, DOE national labs, and other domestic and international collaborators. -
Virginia Walbot
Professor of Biology, Emerita
Current Research and Scholarly InterestsOur current focus is on maize anther development to understand how cell fate is specified. We discovered that hypoxia triggers specification of the archesporial (pre-meiotic) cells, and that these cells secrete a small protein MAC1 that patterns the adjacent soma to differentiate as endothecial and secondary parietal cell types. We also discovered a novel class of small RNA: 21-nt and 24-nt phasiRNAs that are exceptionally abundant in anthers and exhibit strict spatiotemporal dynamics.
