A Perfect Path from Computational Biology to Quantum Computing
Pavol Hell, Simon Fraser University, Burnaby, Canada
Pavol Hell is a Professor Emeritus of Computing Science at Simon Fraser University in Burnaby. After his mathematical studies at Charles University in Prague, he obtained his MSc at McMaster University in Hamilton, and his PhD at the Université de Montréal. Prior to joining SFU, Pavol was an associate professor at Rutgers University in New Brunswick; he has also held visiting positions at a number of universities in Brazil, France, Italy, and the Czech Republic. He was a long term managing editor of the Journal of Graph Theory, and sits on the editorial boards of several other journals. He was named a SIAM Fellow, class of 2012. His area of interest is "computational combinatorics", including algorithmic graph theory and complexity of graph problems. His current focus is on nicely structured graph and digraph classes, and on the complexity of various versions of graph and digraph homomorphism problems.
Deborah Oliveros, Universidad Nacional Autónoma de México, México
Deborah Oliveros Braniff received her B.A., M.A., and Ph.D. in Mathematics from the Universidad Nacional Autónoma de México (UNAM). She was a postdoctoral fellow at the University of Calgary, in Canada, where she held an academic position for 7 years. In 2005, she joined the Instituto de Matemáticas at UNAM, where she is now a “Titular B” researcher. Deborah is a fellow of the Academia Mexicana de Ciencias, a Level III national researcher at the prestigious Sistema Nacional de Investigadores (SNI), and she is founding member and current director of the Unidad Juriquilla del Instituto de Matemáticas, in Querétaro, Mexico. Her research interests center in Discrete and Computational Geometry, as well as in Convexity. Her main contributions follow paths on Helly-type Problems, Transversal Theory, Convex and Abstract Polytopes and Construction of Bodies of Constant Width.
Tverberg type Theorems: The study of partitions of points as simplicial complexes
Gelasio Salazar, Universidad Autónoma de San Luis Potosí, México
After obtaining B.Sc. and M.Sc. degrees in Physics, Gelasio Salazar received his Ph.D. in Mathematics in Ottawa. He held a postdoctoral position at Georgia Tech, and was visiting professor at the Ohio State University and at the University of Waterloo. He has been a professor at the Institute of Physics at the Universidad Autónoma de San Luis Potosí for over 20 years. Gelasio started working in Topological Graph Theory in the boom of the early 1990s, after the Robertson and Seymour proof of Wagner's Conjecture. Later on he also got interested in Geometric Graph Theory, and in the application of Probabilistic and Extremal Graph Theory techniques in both Geometric and Topological Graph Theory. As part of a midlife crisis he has stubbornly (and sometimes successfully) tried to shed some light on some classical Knot Theory problems using elementary combinatorial techniques.
