(On Wednesday June 17th, we will celebrate Joaquin Marro's 70th Birthday.) Organized by the University of Granada, and endorsed by RSEF, EPS and APS among others. Updated information concerning program, submission of abstracts, lodging, etc. at http://ergodic.ugr.es/cp/, or contact us at seminar@eurocongres.es. Some talks will be invited from submitted abstracts (deadline May 31st). ------ Subject: Workshop on Cell Motility, Morphogenesis and Pattern Formation From: Emily Anderson Date: April 15, 2015 New Mathematical and Computational Problems involved in Cell Motility, Morphogenesis and Pattern Formation (CGPW04) Dates: 7th December 2015 to 11th December 2015 Location: Isaac Newton Institute for Mathematical Sciences, University of Cambridge, UK. Cell motility, morphogenesis, and pattern formation are essential features of cell dynamics. The involved biochemical processes and biomechanical properties range from the intracellular level over cell surface dynamics, cell-cell and cell-tissue interactions up to the scale of cell population behaviour influencing organ formation and functioning. The aim of this workshop is to bring together scientists working on these timely and challenging topics of mathematical biology, analysis and numerics. It will provide both an international framework and motivation to further develop the modelling of the mentioned biological phenomena and to strengthen the synergies between the involved branches of applied mathematics, but also between mathematics and life sciences. Application deadline: 27 September 2015 Further details and application: http://www.newton.ac.uk/event/cgpw04 ------ Subject: Workshop on Cell Mechanics, Morphogenetics and Pattern Formation From: Emily Anderson Date: April 15, 2015 Cell Mechanics, Morphogenetics and Pattern Formation: perspectives from the experimental and theoretical points of view (CGPW02) Dates: 14th September 2015 to 18th September 2015 Location: Isaac Newton Institute for Mathematical Sciences, University of Cambridge, UK. The mechanical characterisation of individual cells is complex and dynamic. Nonetheless, great progress has been made in understanding how the dynamics of subcellular structures leads to cell shape and motility. Static tissues have also been well characterised. It is at the level of morphogenesis where the bridging of scales between individual cell dynamics and tissue dynamics is least understood. This workshop aims to (1) present a framework for understanding what is already known about cell-level and tissue-level mechanics, (2) identify gaps in our understanding of how cells interact mechanically in tissues in order to actuate morphogenesis, (3) propose new collaborations to increase our understanding of the cell-tissue emergent dynamics. We will bring together experts in development, microscopy, image analysis, biomechanics, and modeling. Deadline for applications: 12 July 2015 Further details and application: http://www.newton.ac.uk/event/cgpw02 ------ Subject: Graduate School on Evolution Equations, UK From: Heiko Gimperlein Date: April 15, 2015 We would like to bring to your attention the "2nd Maxwell Institute Graduate School on Evolution Equations", to be held at the International Centre for Mathematical Sciences (ICMS) in Edinburgh on 16-18 September 2015. Arnulf Jentzen (ETH Zurich) and Alessandra Lunardi (Parma) will give short courses (4-6 hours) on the numerical analysis of stochastic evolution equations (Jentzen) and on semigroup theory and invariant measures for parabolic problems (Lunardi). Abstract of the mini-courses can be found below. Their lectures will be complemented with talks by senior participants and advanced students. We expect to have some limited funding for postgraduate students, in particular for students from Scottish universities.

The programme provides training in advanced mathematical techniques including partial differential equations and stochastic processes. Moreover, it exposes students to a broad variety of biological and medical applications, ranging from subcellular processes such as gene regulation to organ-level dynamics. In particular the MSc offers practical experience in modelling dynamics in neuroscience, cardiac dynamics, cancer, inflammation and plants. Overall the MSc in Mathematical Medicine and Biology is an interdisciplinary postgraduate degree that combines exciting mathematical research areas with a wide range of practically relevant biological and medical questions. The programme currently offers 5 taught modules, which is followed by a dissertation. During the taught portion of the course students are introduced to key modelling concepts and numerical approaches in Mathematical Biology. In addition, advanced mathematical techniques are covered that allow students to successfully engage with today's challenges in biology and medicine. The dissertation provides students with an exciting opportunity to study a specific topic in more detail.
