BICS is pleased to announce that it will be holding a summer school in "Modelling across the scales" at the University of Bath, UK, 26th-30th June 2006. Multi-scale structure is a key component of many (if not all) complex systems where phenomena at one scale can produce unexpected results at another. The emphasis of the summer school will mainly be on training in mathematical techniques, particularly differential equations, but this will be put firmly in the context of applications. The course will have a core component of four instructional courses in both the theory and the application of multi-scale methods to complex problems presented by leading researchers in the field. In addition there will be a number of cutting edge research talks. The four main speakers/topics are A: Modelling and analysis of multiple scale problems (J. Zimmer) B: Modelling and simulation of Microstructure Evolution (C. Carstensen) C: Multi-scale analysis and stochastic differential equations (R. Kuske) D: Multi-scale behaviour in the geo-sciences (H. Muhlhaus) The Summer School is funded by EPSRC. Persons interested in attending will find further information at http://www.bath.ac.uk/math-sci/bics/summerschool/ Queries could be addressed to Mrs. Ann Linfield at bics@maths.bath.ac.uk ------ Subject: PhD Position in Mathematical Modelling of Bioinvasions From: Horst Malchow Date: Tue, 20 Dec 2005 08:30:01 +0100 The Institute of Environmental Systems Research at the Department of Mathematics and Computer Science of the University of Osnabrueck (www.usf.uos.de) has an opening for a PhD Position in Mathematical Modelling of Bioinvasions and Epidemic Spread (Salary 50% BAT IIa) for a duration of three years, starting from April 1, 2006. Biological invasions and the spread of infectious diseases have been attracting considerable attention due to their numerous adverse effects on ecosystems dynamics and biodiversity. Although a considerable progress has been made during the last decade in understanding basic scenarios of species invasion, many important issues have not been properly addressed yet. Comprehensive identification of factors that affect rates of invasion and patterns of species spread and that can potentially either enhance or hamper species invasion, is expected to open the possibility of biological control and to result in effective invasive species management. Research will focus on equation-based, deterministic and stochastic reaction-diffusion modelling of invasion phenomena and their analysis. Teaching (exercises/tutorials in theoretical systems science) is required two hours per week. Candidates should hold a master or diploma degree in applied mathematics, physics or an interdisciplinary field such as mathematical and theoretical biology, environmental modelling or systems science. Experience in equation-based reaction-diffusion modelling, complex systems analysis and numerical methods (solution of systems of deterministic and stochastic partial differential equations, bifurcation analysis, etc.) will be of major advantage. Please send your application until January 31, 2006 to Prof. Dr. Horst Malchow [malchow(at)uos.de; http://www.usf.uos.de/~malchow] Institute of Environmental Systems Research, University of Osnabrueck D-49069 Osnabrueck, Germany. Informal enquiries should also be addressed to Horst Malchow. The University of Osnabrueck is an equal opportunity employer. ------ Subject: Assistant professor position in Boulder From: James Meiss Date: Tue, 20 Dec 2005 17:41:47 -0700 University of Colorado at Boulder Tenure Track Assistant Professor in Applied Mathematics Applications are invited for an Assistant Professor in the Department of Applied Mathematics to begin August 2006.
