​Aldo Conca received a Ph.D. in mathematics from the University of Essen (Germany) in 1993. Since 2000 he has been a professor of algebra at the University of Genova (Italy). His main research interest lies  in commutative algebra and its interactions with algebraic geometry and combinatorics.  Joseph Gubeladze graduated from Tbilisi State University in 1983. He received his Ph.D. in mathematics in 1985 and Doctor of Science in 1990 from St. Petersburg State University. He worked at Razmadze Mathematical Institute in Tbilisi from 1983. After several research positions in Europe and the USA, he joined San Francisco State University in 2003, where he is currently a professor of mathematics. He is interested in K-theory of toric varieties and lattice polytopes. Tim Römer received his Ph.D. from the University of Essen (Germany) in 2001. Since 2008 he has been a professor of algebra at the University of Osnabrück (Germany). His main research interests are in the area of commutative algebra with applications to algebraic/discrete geometry, algebraic combinatorics and algebraic statistics.
