Elizabeth Villa (PI)
As a young physicist, Elizabeth was impressed by the ability of biology to operate on many length and time scales in order to perform its functions. She began her incursion into biomedical sciences by trying to develop methods that could make challenging problems that bridge multiple scales tractable for simulations.
During her graduate studies in the lab of Klaus Schulten as a Fulbright Fellow, she worked on computational methods to combine scales into molecular simulations. In that process, she was lucky to learn about cryo-electron microscopy (cryo-EM) from Joachim Frank in a very productive collaboration that led to the development of a method to combine X-ray crystallography structures with cryo-EM data using molecular dynamics simulations (Molecular Dynamics Flexible Fitting). This opened her eyes to the power of electron microscopy, and she saw an opportunity to use it as a biophysical tool that could not only unveil averaged structures of macromolecules, but could show how they operate in their natural environment.
A short stint in the Marine Biological Laboratory (MBL) for Physiology Course convinced her that open problems in cell biology needed quantitative questions posed in the context of the structural environment in which macromolecules operate.
She decided that to work in the problems in cell biology that interested her, she needed to compliment her skills by becoming an experimentalist. She obtained a Marie Curie Postdoctoral Fellowship to work in the lab of Wolfgang Baumeister at the Max Planck Institute of Biochemistry in Munich, where she learned and developed tools to realize the power of cryo-electron tomography for cells.
Combining these multidisciplinary skills, her lab at UCSD is fully equipped for taking on the challenge of quantitative cell biology, using tools from cell biology, cryo-electron microscopy and tomography, computational analysis, and integrative modeling. This potent combination enables the visualization of macromolecular complexes in their native environment and derive their structure, context, and interaction partners.
Her current research is focused on studying the nuclear periphery, as nuclear biology remains one of the most exciting challenges in the cell, and it is uncharted territory structurally. Her lab also pursues many collaborations aimed at understanding the bacterial cytoskeleton, studying Parkinson’s disease. In 2016, she was granted an NIH Director’s New Innovator Award in 2016, which allows her to pursue high-risk high-reward research developing tags for cryo-electron tomography (cryo-ET), and developing new technological and computational techniques to advance structural cell biology.
