Tracy Punshon


Tracy Punshon earned her BSc in Applied Biology in 1992 and a PhD in Plant Biology in 1996 from Liverpool John Moore’s University (UK). Tracy studied metal tolerance and resistance in plants, specifically in fast growing willow species for her PhD studies and is currently a Research Assistant Professor in the Department of Biology at Dartmouth College.

Tracy uses spatially resolved elemental analysis (elemental mapping) to understand the biochemistry of metals in biological systems, including essential and contaminant elements. She specializes in the use of two spatially resolved metal analysis techniques: synchrotron x-ray fluorescence  (SXRF) imaging and laser-ablation interfaced with ICP-MS. Tracy oversees and conducts the spatially resolved elemental analysis for the Trace Element Analysis Core. She has conducted elemental mapping studies on a wide range of environmental and biological specimens, including soil, plants, and human tissues.

Tracy has conducted research at three U.S. synchrotron facilities, and a total of six individual beam lines, including the National Synchrotron Light Source  X26A and X27A, Advanced Photon Source 2-ID-D and 13-ID-E Stanford Synchrotron Radiation Lightsource  BL2-3 and 10-2.
