Judy Stone, MT (ASCP), PhD, DABCC has worked with LC-MS in diagnostic laboratories since 1999. Her clinical practice involved small molecule method development, instrument to instrument and instrument to LIS interfacing, LC-MS automation, monitoring quality of LC-MS methods in production and staff training for clinical LC-MSMS. She served as faculty chair for the 2009 AACC online certificate program “Using Mass Spectrometry in the Clinical Laboratory”, as a scientific committee member for the MSACL Practical Training track, and was editor-in-chief for the AACC Clinical Laboratory News quarterly feature series on Clinical LC-MS. She enjoys documenting and presenting esoteric as well as absurdly common LC-MS problems in creative ways in order to help trainees learn troubleshooting (and avoid repeating her mistakes).

Grace van der Gugten, B.Sc. Chemistry Provincial Health Services Authority, BCCDC Toxicology Lab
Grace discovered her love for clinical mass spectrometry when she began working at St Paul's Hospital in Vancouver in the special chemistry mass spec group with Dr. Dan Holmes in late 2010. Grace was challenged in this role but gained a wealth of knowledge and experience over her 10+ years in the SPH laboratory. She puts this experience and knowledge into use in her current role as Mass Spectrometry Lab Scientist in the Toxicology Lab at the BCCDC in Vancouver, BC. Grace loves developing streamlined, easy to use (if possible!) clinical mass spectrometry assays; teaching others and helping others succeed; and troubleshooting (especially when the problem is solved!).
