Kieval Lecture

Join us for the 77th Kieval Lecture

The Humboldt Department of Mathematics presents this lecture series. Named for Humboldt Mathematics Professor Emeritus. Dr. Harry S. Kieval taught at Humboldt from 1966 to 1979; the series includes topics on popular and/or broad aspects of mathematics attractive to undergraduates and the public.

The 77th Kieval Lecture will take place on the evening of Thursday, April 7, 2022 at 7:00 PM in SCI B 135. The speaker is Dr. Jesús De Loera from UC Davis. His talk is titled Simple Problems that are Very Hard to Solve: My Favorite Unsolved Problems about Polyhedra.

Dr. De Loera’s research is in the areas of Combinatorial and Computational Applied Mathematics.  He was born and raised in Mexico City, and completed his B.S. in Mathematics at the National University of Mexico in 1989.  He completed his Ph.D. in Applied Mathematics at Cornell University under the supervision of Dr. Bernd Sturmfels, and has been a member of the faculty at UC Davis since 1999.  He has held visiting positions at the University of Minnesota, the Swiss Federal Technology Institute (ETH Zürich), the Mathematical Science Institute at Berkeley (MSRI), Universität Magdeburg (Germany), the Institute for Pure and Applied Mathematics at UCLA (IPAM), the Newton Institute of Cambridge Univ. (UK), and the Technische Universität München.  He is an expert in the field of Discrete Mathematics, but his research encompasses a diverse set of topics including his work in (pure) Convex Geometry, Algebraic Combinatorics, and Combinatorial Commutative Algebra, as well as his (applied) work in Combinatorial Optimization and Algorithms. In addition to more than 90 published research papers, he has co-written two graduate level textbooks: "Triangulations: Structures for Algorithms and Applications'' (Springer, with J. Rambau and F. Santos) and "Algebraic and Geometric Ideas in the Theory of Discrete Optimization'' (SIAM, with R. Hemmecke and M. Koeppe).  For his dedication to outstanding mentoring and teaching he received the 2003 UC Davis Chancellor's fellow award, the 2006 UC Davis award for diversity, the 2007 Award for excellence in Service to Graduate Students by the UC Davis graduate student association, and the 2013 Chancellor's award for mentoring undergraduate research. In 2017, he was awarded the Mathematical Association of America Golden Section Award for Distinguished College or University Teaching of Mathematics, and in 2018 he won the UC Davis College of Letters and Science Distinguished Teaching Award. He has successfully supervised fourteen Ph.D students, eight postdoctoral scholars, and over 50 undergraduates doing research projects.  See https://www.math.ucdavis.edu/~deloera/bio.htm for further details about Dr. De Loera's work.
