## Work Experience
### cryoFIB-SEM scientist @ Chan Zuckerberg Biohub Network
Jan 2023 – Present | San Francisco Bay Area
At the Chan Zuckerberg Imaging Institute we aim to cure, prevent, or manage all diseases by the end of the century by developing new imaging hardware and software tools. I am part of a collaborative team that uses cryo tomography to probe cellular organization at molecular resolution using state-of-the-art technology.

### Staff Engineer @ Chan Zuckerberg Biohub Network
Jan 2023 – Present | San Francisco Bay Area

### Imaging Scientist @ Chan Zuckerberg Initiative
Jan 2021 – Jan 2024

### Assistant Director in the Center for Advanced Cryo Electron Microscopy @ University of California, San Francisco
Jan 2020 – Jan 2024 | San Francisco, California, United States
Since joining the cryoEM team at UCSF I have established and set up cutting-edge technologies to bring cellular Cryo-tomography to the research community at UCSF. We now have the capabilities to image frozen, hydrated cells by Cryo light microscopy, mill windows into cells using Cryo Focused Ion Beam - Scanning Electron Microscopy (cryoFIB-SEM) and then generate high-resolution cryoEM data to answer cell-biology questions in situ.

### Research Specialist @ Howard Hughes Medical Institute
Jan 2016 – Jan 2020 | University of California, San Francisco

### HHMI Postdoctoral Fellow @ University of California, San Francisco
Jan 2011 – Jan 2016
For my postdoctoral research I moved to the University of California, San Francisco to learn how to use Cryo Electron Microscopy to probe the inner workings of cells. During my time at UCSF I studied centriole structure and how its structure is adapted to form centrosomes and cilia.

### Graduate Student @ Max Planck Institute of Molecular Cell Biology and Genetics
Jan 2005 – Jan 2011
Cell Biology

### Research Assistant @ Harvard University
Jan 2004 – Jan 2006 | Boston, MA.
Post-university research experience in the Department of Cell Biology at Harvard Medical School, developing skills in mammalian-cell tissue culture, cell transfection, fluorescence imaging, and monoclonal antibody generation.
