DESCRIPTION:Benoît Chachuat\, ICL\nBio: My research interests are in the 
 general area of Process Systems Engineering (PSE)\, with emphasis on globa
 l optimization\, optimization-based process control\, and numerical comput
 ation. My primary research objective is to develop new methods\, concepts 
 and tools for the fast and reliable optimization of complex process system
 s.\nApplications in the field of process design and operations aim to deve
 lop safe\, environmentally and economically sustainable (bio)chemical proc
 esses\, including micro power generation\, integrated biotechnological pro
 cesses for bioenergy production and waste treatment. Other applications ar
 e in the field of signal transduction in systems biology.\nMany engineerin
 g design and control problems can be formulated naturally in a set-theoret
 ic framework. A number of key set-theoretic concepts were proposed in the 
 early 1970s\, but their systematic application was not possible until enou
 gh computational capability became widely available. Today\, many such met
 hods and tools are available for the estimation and control of linear syst
 ems - witness the popularity of Matlab's multi-parametric toolbox - but it
  is less so for nonlinear systems. In this presentation\, we give an overv
 iew of recent developments in set-theoretic methods for nonlinear systems 
 in our research group. Central to these approaches is the ability to compu
 te tight enclosures of the range of multivariate systems\, e.g. using elli
 psoidal calculus or higher-order inclusion techniques based on multivariat
 e polynomials\, as well as the ability to propagate these enclosures throu
 gh time for bounding dynamic systems. We illustrate these developments wit
 h a range of applications\, including the determination of all equilibrium
  points and bifurcations in a given domain\; the reachability analysis of 
 nonlinear ODE or DAE systems\; and the solution of set-membership paramete
 r estimation problems.
