Prof. Yunqing Huang

Yunqing Huang, Vice president of CSIAM, is a professor of mathematics from Xiangtan University. He obtained his PhD degree from Chinese Academy of Sciences in 1987 and became a full professor in 1993. He started his career in investigating high accuracy analysis of finite element method, such as superconvergence, extrapolation, postprocessing, posteriori estimates etc. He and coauthors proposed a combination of local refinement and mesh optimizations with an adaptive procedure to keep the superconvergence property of the finite element approximations. Their methods ensure that the recovery techniques can guarantee the efficiency of posteriori error indicators. They proved that the local approximation being better than the global error is a sufficient condition for noncomforming element to produce lower bounds for the finite element approximations of the eigenvalues of elliptic operators. This result can be a guide for modifying existed elements which do not provide lower bound as well as inventing new elements. Another research direction of Prof. Huang is the finite element analysis of electromagnetic field in metamaterials. He and coauthors obtained optimal error estimates and superconvergence for various models. They have also worked on modeling and simulations on backward wave propagation and electromagnetic cloaking, including carpet cloak, cylindrical, elliptical cloaks, etc.

Prof Huang has received numerous distinguish awards, such as the sixth Feng Kang Scientific Computing Award, the First Class Natural Science Award of the Ministry of Education, the First Class Natural Science Award of the Hunan Province, the Second Class National Award in Teaching Achievements. He is also the Chief Editor of AAMM(Advances in Applied Mathematics and Mechanics), and recipient of the National Science Fund for Distinguished Young Scholars.

Prof. James Sethian

James Sethian is Professor of Mathematics at the University of California at Berkeley and is the Director of the Center for Advanced Mathematics for Energy Research Applications (CAMERA) at the Lawrence Berkeley National Laboratory, which develops new mathematical and computational techniques for analyzing data that come from synchrotron light sources.

Sethian's research has been focused on computational methods for moving interfaces in fluids and materials, and has applied these techniques to a host of scientific and engineering problems, including applications to fluid mixing, semiconductor modeling, wave propagation in materials, industrial jetting and printing devices, image processing, combustion modeling, and industrial foams. He is a fellow of SIAM and of the AMS, is a member of both the US National Academy of Sciences and the US National Academy of Engineering, has received the ICIAM Pioneer Prize and the joint SIAM-AMS Wiener Prize, and was a plenary speaker at ICIAM in 1999. He received his PhD from the University of California at Berkeley, and B.A. from Princeton University.

Prof. Anna-Karin Tornberg

Anna-Karin Tornberg is a professor in Numerical Analysis at KTH since 2012. Her research concerns the development of numerical methods for the solution of PDEs. One specific focus is on boundary integral methods for fluid flows involving particles and drops. She was recently (2014) awarded the Göran Gustafsson prize in Mathematics. She is an elected member both of the  Swedish Royal Academy of Sciences (KVA) (since 2010)and of the Swedish Royal Academy of Engineering Sciences (IVA) (since 2015). Earlier awards include the selection as an Alfred P. Sloan research fellow (2006) while Prof. Tornberg was part of the faculty at the Courant Institute of Mathematical Sciences (New York University) as well as the Leslie Fox First Prize in Numerical Analysis (2000).

Prof. Tornberg has been an associate editor for Journal of Computational Physics for eight years. She has served on several grant evaluation panels and PhD committees both nationally and internationally. In 2014 she was a member of the organizing committee for the SIAM (Society of Applied and Industrial Mathematics) annual meeting in Chicago and in 2017 for the SIAM CSE meeting in Atlanta.

Prof. Isabelle Gallagher

Isabelle Gallagher is Professor of Mathematics at Paris-Diderot University and at the Ecole Normale Suprieure of Paris. Her principal theme of research concerns the mathematical anal- ysis of Partial Differential Equations related to Fluid Mechanics, through two different points of views: their derivation, and their resolution.

From the derivation point of view, she is interested in the passage from the microscopic description of fluids to their macroscopic description. More precisely, following Hilbert’s sixth problem, the question is to understand how to reconcile Newton’s laws for classical particles constituting the fluid and macroscopic PDEs such as the Euler or Navier-Stokes equations. This has been in particular the subject of joint efforts with Thierry Bodineau and Laure Saint-Raymond in the past few years.

From the resolution point of view, she is mostly interested in understanding the behaviour of smooth solutions to the Navier-Stokes equations, associated with smooth initial data in three space dimensions: solving globally those equations for general initial data is a long- standing open question, and together with a number of collaborators she has been trying to understand the behaviour of solutions, whether near blow up time (supposing such solutions exist) or in large times.

She was an invited speaker at ICM 2014 and ECM 2012, and the recipient of the CNRS Silver Medal in 2016.
