Academic Bio

Dr. Charles Hawker is Scientific Director for Automation and Special Projects at ARUP Laboratories, where he has been for over 22 years. At ARUP he has installed several major automation and robotic systems that have made ARUP one of the world's most automated laboratories. He is a frequent lecturer on clinical laboratory automation at national and international meetings. Dr. Hawker has received the 2014 AACC Outstanding Lifetime Achievement Award in Clinical Chemistry and Laboratory Medicine. He also received the 2013 AACC MSPSD Division Award for Outstanding Contributions to Management Sciences and Patient Safety, and AACC Outstanding Speaker Awards for 2000, 2007, and 2009. He has also received the John V. Bergen Award of the Clinical and Laboratory Standards Institute, the Proefssor Alvin Dubin Award from the National Academy of Clinical Biochemistry (NACB) for contributions to the profession and the Academy, a Diploma of Honor from the Association of Clinical Scientists (ACS), and the Becton Dickinson Award from the Association for Laboratory Automation. He is a past President of the NACB, the ACS, and the Clinical Ligand Assay Society, and also served two terms as Secretary of NACB and is the current Secretary of the ACS. He has chaired several automation committees in both CLSI (NCCLS) and Health Level 7 and currently chairs a CLSI Document Development Committee for 2D Barcodes. He is a co-author or author of chapters on clinical laboratory automation in the 4th and 5th Editions of the Tietz Textbook of Clinical Chemistry and Molecular Diagnostics, the 6th and 7th Editions of the Tietz Fundamentals of Clinical Chemistry, and in Clinics in Laboratory Medicine (December, 2007). He has published ten other invited reviews or chapters, 43 peer-reviewed articles, 47 abstracts, and holds 3 patents. His published research ranges from radioimmunoassay of parathyroid hormone to clinical laboratory automation systems, but he is especially proud of a 1983 publication on the measurement of calcitonin in patients with toxic shock syndrome, a paper that provided the empetus for the identification of procalcitonin as a precursor to calcitonin and its use as a marker for septic shock. His most recent research was the development of an automated camera system that can use OCR/OCV technology to identified patient name mislabeled specimens published in Clinical Chemistry in March, 2014.
