Shannon Haymond
Chair Elect

HaymondI am the director of the Clinical Chemistry laboratories at Children's Memorial Hospital in Chicago. In this capacity I also hold a faculty appointment as an assistant professor of pathology at Northwestern University's Feinberg School of Medicine. Like many laboratory directors, my job is a mix of providing clinical service, teaching pediatric clinical chemistry to residents and fellows and performing clinical research. My research interests include method development and quality initiatives for tandem mass spectrometry applications and improving utilization of and access to laboratory results in the pediatric primary care setting. I have been actively involved with AACC at both the national (2011 SYCL committee and AMOC 2010 brown bag coordinator) and local level (2011 Chicago local section past chair). I am grateful to serve as the Chair Elect of the PMF division.
