1 Presenters Workshop Schedule Daniel Tholen: Convener of ISO/CASCO WG 28 for drafting ISO/IEC and ISO/TC69 WG for revising ISO Currently, Dan is the ILAC Liaison for TC69 - the ISO Committee for Application of Statistical Methods; and he is a lead assessor for accreditation to ISO/IEC and ISO Guide 34, on behalf of several accreditation bodies. Christian Bläul: head of QuoData's research and technology department. QuoData, based in Dresden, Germany, specializes in the application of statistics for quality assurance. Of central importance is the evaluation of interlaboratory studies in connection with the assessment of laboratory performance and the validation of measurement methods. Christian has not only many years experience speaking in seminars (e.g. in-house training events) and conferences, but is also a driving force in the development of QuoData s cornerstone product for PT, PROLab. Coordinator Angela Oler: AIHA PAT In general, AIHA Proficiency Analytical Testing (PAT) Programs assist participants in pursuing excellence in laboratory services via external quality assessment. Their testing programs allow participants to demonstrate their ability to correctly analyze workplace and environmental samples.
