Research Interests

The first time I watched a time-lapse recording of a living cell I became fascinated by the power of digital microscopy.  The discovery of GFP and its application to visualize dynamic events inside of cells has revolutionized modern cell biology.  I first used this enabling technology to study the structural proteins that give a neuron its shape and moved on to study membrane protein trafficking when I arrived in Portland. In my current role as the Director of the Advanced Light Microscopy Core I get to discuss imaging projects with students, postdoc and faculty, teach them the use of the high-end equipment in the Core, and share their excitement when the images obtained are revealing for their research.


Dr. Kaech Petrie obtained her Ph.D. in Cell Biology in 1991 at the University of Basel, Switzerland. After a short post-doctoral experience at NINDS-NIH in Bethesda, Maryland, she joined the laboratory of Dr. Andrew Matus at the Friedrich Miescher Institute in Basel, Switzerland, where she specialized in visualization of dynamic processes in living cells using GFP, a technology just emerging at that time.  She joined Dr. Gary Banker's laboratory at OHSU in 2000 and transitioned to become the Director of the Advanced Light Microscopy Core at The Jungers Center in 2009.
