About
The Advanced Light Microscopy Core at the Jungers Center was established in 2009 through collaborative efforts of the University Shared Resources Program and the Departments of Neurology and Molecular Microbiology and Immunology, the Jungers Center for Neurosciences Research, and the Oregon Hearing Research Center. Technical expertise and instrumentation was pulled into a shared resource to serve OHSU researchers in need of fluorescence microscopy.
Meet the Staff
Stefanie Kaech Petrie: Director
Stefanie puts 100% effort into developing and running programs to enhance advanced light microscopy at OHSU. She has over three decades experience with advanced instrumentation for light microscopy and was among the first neuroscientists to take up the use of GFP technology. Her past research includes visualizing microtubule- and actin-based cytoskeletal rearrangements and membrane protein trafficking in neurons. Contact Stefanie
Brian Jenkins: Senior Core Scientist
Brian’s imaging experience spans 10+ years in the neuroscience field using several microscope modalities with a focus in live-cell imaging. Brian’s passion for microscopy began as an undergraduate in San Diego, further developed during graduate school in Oregon, and sharpened as a postdoc in Wisconsin. His main interests reside in how the neuronal cytoskeleton influences protein trafficking and neuronal morphology. In the core, he enjoys assisting researchers image their samples in a meaningful way while teaching the basics of light microscopy. Contact Brian
Felice Kelly: Core Scientist
Felice uses microscopy to explore the beauty of the cellular world and better understand spatially organized cellular functions. She has over a decade of experience imaging single-celled organisms and sub-cellular structures in live and fixed cells, including as a graduate student at Rockefeller University working on fission yeast, as a post-doc at Stanford studying the parasite Toxoplasma gondii, and as a senior scientist in Scott Landfear’s lab at OHSU investigating the parasite Leishmania mexicana. She particularly enjoys assisting users with high-resolution imaging (for example, protein co-localization and sub-organellar structures) but is eager to help with all of your projects. When she’s not appreciating the microscopic world she can be found running or skiing through the mountains and forests of the Pacific Northwest. Contact Felice
Former staff
Hannah Bronstein: Associate Core Scientist
Hannah was a member of the ALMC from 2019 to the summer of 2025. During that time, she trained over 300 users on the microscopes and analysis platforms available at the ALMC. She moved to Salt Lake City in the Summer of 2025 to pursue her PhD in molecular biology at the University of Utah. Before working at the core, Hannah received her bachelor's degree in biology from Reed College where she studied stem cell niches of the zebrafish retina. In her free time, she loves skiing, climbing, and hiking, and is very excited for the outdoor opportunities Utah has to offer.
Crystal Chaw: Senior Research Associate
Crystal was a member of the ALMC as a Senior Research Associate from 2017 to summer of 2021 where she trained and consulted researchers at the Knight Cancer Institute. Before OHSU, Crystal was a postdoctoral researcher at the University of California, Riverside in the Hayashi lab studying spider biology, and received her PhD from the University of California, Berkeley in the Patel lab. In the summer of 2021, inspired by her love of teaching and mentoring young scientists, Crystal moved to Reed College to become a Lecturer and Biology Lab Instructor.
