Summary of Qualifications
Dr. Michael Bussieck has a PhD in Mathematics from Technical University of Braunschweig, Germany. He worked from 1998 to 2004 at GAMS Development in Washington DC, USA as a senior optimization analyst. Since 2004 he has also been a managing partner of GAMS Software GmbH, leading the GAMS software development group. In addition to his development responsibilities, he frequently engages in customer optimization projects that deliver cutting-edge optimization technology to clients from industry (energy, automotive, and chemical), the military, and government throughout Europe and the US.
Michael has published in many first class optimization journals, frequently gives lectures at international conferences, and leads the academic outreach program at GAMS. He also serves as a member in the advisory board of the German OR Society.
