Casey Johnny

 Casey earned her undergraduate degree in Biochemistry and Molecular   Biology from Michigan State University where she was involved in a   research study in algae lipid metabolism. Her interest in research led her   to pursue a Ph.D. in Cell and Molecular Biology where she was involved in understanding the transport of diterpenes between the plastid and   endoplasmic reticulum using Arabidopsis as a model plant. During her   Ph.D. work, she developed analytical methods for extraction and quantification of various diterpenes, including gibberellins, by GC-MS and LC-MS/MS using instruments at the RTSF Mass Spectrometry and Metabolomics Core Facility. After graduating, she joined the core in October 2018 and acquired expertise in the area of GC-MS. Casey has experience in various volatile sampling techniques such as solid phase microextraction and purge-and-trap. She also has experience in sample preparation and derivatization techniques amenable to GC-MS analysis. In addition to GC-MS, she has experience developing targeted LC-MS/MS methods. Currently, she is shifting her focus more towards imaging mass spectrometry with the addition of the Bruker ultrafleXtreme MALDI-TOF/TOF system in the facility. Outside of the core facility, she enjoys being outdoors with her family.
