The Advanced Light Microscopy Core @ The Jungers Center was established in 2009 through collaborative efforts of the University Shared Resources Program and the Departments of Neurology and Molecular Microbiology & 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.


Stefanie Kaech Petrie – Director

Stefanie puts 100% effort into developing and running programs to enhance advanced light microscopy at OHSU and serves as key consultant to neuroscientists supported through a NINDS P30 Core Center Grant.  She has more than 15 years 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.

Aurelie Snyder – Imaging Specialist

Aurelie started out as a registered histochemistry technician who was fascinated by the power of fluorescence microscopy.  She specializes in the application of image restoration through iterative deconvolution and enjoys the challenge of developing protocols to capture dynamics in your living specimens and reconstruct and analyze 3D information using Bitplane Imaris.  Her imaging experience includes many types of tissues and cells, from whole mount corneas to large and small brain bits, to bacteria, virions and parasites. 

Crystal Chaw – Imaging Specialist

Crystal is an evolutionary developmental biologist who has over 12 years of experience with immunostaining and confocal microscopy. Her light microscopy experience was refined during her undergraduate and PhD training, where she used a variety of techniques to investigate early cell migration in spider and crustacean embryos. Crystal especially enjoys developing protocols for novel problems, be it specimen preparation for a microscope or an analysis pipeline for software like Bitplane Imaris. She is primarily responsible for the instruments in the Collaborative Life Sciences Building at the South Waterfront Campus.


ALM Core instruments are divided between Marquam Hill and the South Waterfront.→ See map

Marquam Hill: The ALM core is on the 4th floor of the Hildegard Lamfrom Biomedical Research Building in rooms LBRB 451, LBRB 474, LBRB 476, LBRB 478, and LBRB 481.  The director's office is LBRB 405. 

South Waterfront: The ALM core is in the microscopy suite on Parking level 2 in the basement of the Collaborative Life Sciences Building in rooms P2N006 and P2N010
