In February 2018, ANODE will be revived, with a very simple format in which participants will be allotted generous speaking times, with everyone on an equal basis. It will be held in the beautiful city of Auckland towards the end of what is expected to be a mild and pleasant summer. This preliminary announcement is a call for expressions of interest from possible participants. For a copy of an expanded version of this announcement, and further details and updates as they become available, see http://tinyurl.com/ANODE2018. If you are interested and wish to be on the mailing list for further informtaion as it comes to hand, pleaae write to John Butcher at butcher@math.auckland.ac.nz Please tell John, if you can, how likely you are to take part in ANODE 2018 and, if so, whether you will wish to give a talk. You are of course welcome to ask questions about the plans for this conference.

The position is initially limited until August 31, 2019. The salary corresponds to 50% of a full position (19,35 hours per week) at the level of TV-L E13 of the German public service salary scale. We offer the opportunity to undertake doctoral research. The position is part of the research project "Optimization of quality and performance" in the german national climate modeling initiative "From the Last Interglacial to the Anthropocene: Modeling a Complete Glacial Cycle (PalMod, http://www.palmod.de/)", which aims at simulating the climate from the peak of the last interglacial up to the present using comprehensive Earth System Models. A project extension beyond 2019 is planned. Task of the researcher is performance optimization of a high resolution climate model, beginning with the realization of a version of the atmospheric radiation module in single precision arithmetic. Requirements are: Diploma or M.Sc. in computer science, mathematics, climate sciences or related fields; proficiency in procedural programming and handling Unix/Linux systems; experience (or the willingness to familiarize oneself) with FORTRAN- based simulation programs on high-performance computers. Interested candidates should send an application letter including curriculum vitae and copies of transcripts via e-mail to Prof. Thomas Slawig . Please refrain from submitting application photos. Closing date for applications: August 15th, 2017. ------ Subject: Postdoc Position, Population Modelling From: Daniel C Reuman Date: July 20, 2017 Dr Daniel Reuman is recruiting into his lab in the University of Kansas Department of Ecology and Evolutionary Biology (EEB). At least 3 years of funding are available to carry out modelling and numerical analysis of spatial population dynamics. The postdoc will join an interdisciplinary team consisting of Reuman, three postdocs and one student currently in the Reuman lab, collaborators in EEB and in the Math Department at KU, and collaborators at several institutions in the USA and UK. Funding is from the NSF Mathematical Biology program and the James S McDonnell Foundation. We seek individuals from biological or physical-science backgrounds with skills and demonstrable interests in modelling and related areas. Experience with stochastic process modelling and Fourier or wavelet approaches is a plus. Experience with population models and linear and nonlinear dynamical systems is a plus, as are computational skills, particularly if applied in a statistical or modelling context. A PhD or ABD in a related field is required. Applicants from underrepresented groups are encouraged. The University of Kansas (KU) is a major research university with special strength in quantitative ecology and evolutionary biology. KU is located in Lawrence, Kansas, about 30 miles from Kansas City. Lawrence is a progressive and cosmopolitan university town with vibrant art, music, and sports scenes that has been ranked among the top ten college towns in the country for liveability.
