2021 Symposium – X-ray Imaging in Plant Biology: Seeing the Unseen – Keith Duncan

Posted on September 15, 2021


Keith Duncan

Research Scientist – Donald Danforth Plant Science Center

Keith Duncan is a research scientist in Dr. Chris Topp’s lab at the Donald Danforth Plant Science Center in St. Louis, Missouri (USA), and is Director of their X-ray imaging facility. Before coming to the Danforth Center, Keith joined Dr. Rick Howard’s lab in 1990 at the DuPont Experimental Station in Wilmington, Delaware (USA), using light, laser, electron, and X-ray imaging technologies to study all aspects of agricultural cell biology. When that facility was closed in 2016, Keith moved to St. Louis to join Chris Topp’s lab at the Danforth Center and manage the newly opened X-ray imaging facility, one of the first in North America dedicated exclusively to studying plant biology. For the past five years Keith has been using X-ray computed tomography (XCT) to study plant biology both above and below the soil line using a large format high resolution XCT instrument, the NSI X5000. In particular, Keith’s research in the Topp lab is focused on using X-ray tomography to study root system architecture, and grain and flower development in numerous economically important crops like corn, soybean, sorghum, and alfalfa.
