Education and early life

edit

Römisch was born in Zwickau, Germany in 1947. He earned his diploma degree in Mathematics (1971) and doctoral degree in mathematics (1976) at the Humboldt University of Berlin (HUB). In 1984 he earned his Habilitation degree and after that he was appointed as Privatdozent at the HUB. In 1993 he became full professor of applied mathematics at HUB. He is married to Ute Römisch, lives in Berlin and has two children.

Career and research

edit

Römisch is known for being a pioneer in the field of stochastic programming, to which he made several significant contributions. His work on analysis of discrete approximations,[1][2] stability,[3][4][5][6][7] power systems,[8][9] risk quantification and management,[10] scenario reduction[11][12][13][14] and efficient Monte-Carlo sampling[15] are notable contributions to the field. He authored three books and more than 130 research papers. He was co-editor of the Journal of Stochastic Programming E-Print Series (1999–2018), Associate Editor of Optimization Letters (OPTL) (2006–2013), of Energy Systems (2009–2020), of Computational Management Science (2012–2020), and of SIAM Journal on Optimization (2013– ). He is co-author of the algorithm for scenario reduction SCENRED,[16] which is used in several optimization frameworks in the energy industry.

Awards and honours
