Haverford College, Haverford, USA

Experimental Nonlinear Physics

Dear Colleague,
I anticipate that a two-year postdoctoral position for experimental research on granular materials, fluid mixing, and/or pattern formation will be available in my laboratory starting approximately July 1 or August 1, pending funding decisions. The position requires experimental training in nonlinear physics or fluid dynamics and an interest in teaching.

Recent work in our laboratory has included studies of pattern formation and spatio-temporal chaos in nonlinear interfacial waves, and mixing in turbulence. Recently, we have also been working on granular materials. A paper on cluster formation, due to collisions in granular material, recently appeared in Physical Review Letters. A second paper on stick-slip friction in sheared granular layers has been submitted to Science.

We are quite excited about the friction work, which has interesting connections to geophysics, and reveals a number of fascinating and novel results: (a) the first time-resolved measurements of friction forces within individual slip events shows that the frictional force is a multivalued function of the velocity; (b) discrete slip events much smaller than the particle size can occur; (c) microscopic rearrangement or precursor events are found between major slip events. Many extensions of this work are possible. For further information , please consult our web site: http://www.haverford.edu/physics-astro/Gollub/lab.html.

A talented person wishing to explore the possibility of a faculty job in an institution where BOTH research and teaching are valued would have something special to gain from working in this environment and collaborating with undergraduates. One of our talented undergraduate students won the APS Apker Award for his research on fluid mixing. My present postdoc, Arshad Kudrolli, has landed a tenure-track university position with good startup support after 1.5 very productive years here.

Our program is also affiliated with The University of Pennsylvania. We are located in the attractive western suburbs of Philadelphia, close to many universities, cultural activities, and employment possibilities for spouses.

If you know of a suitable candidate, I would appreciate your asking her or him to send me a CV and letter describing background and interests as soon as possible and not later than May 30. Two letters of reference would eventually be needed, but one would be fine for now. Haverford College is an equal opportunity/affirmative action employer. An E-MAIL response is fine: Ascii files can go to me; Postscript files should be directed to our secretary ( kmcgoldr@haverford.edu), marked for my attention.

University of Dundee

Centre for Nonlinear Systems in Biology

Department of Mathematics, University of Dundee

Scottish Crop Research Institute

Post-Doctoral Research Assistant in Mathematical Biology

Applications are invited for a BBSRC-funded project concerned with a combined mathematical and experimental study of the effect of heterogeneity in soil structure and moisture on microbial dynamics. The post is due to commence 1 October 1997 for 3 years.

The project will involve the mathematical modelling of microbial movement (nematodes) through a heterogeneous medium (soil). Specific aims of the project include developing a theoretical relation between moisture content, soil structure and connectivity of water-filled pores; modelling diffusion in partially saturated fractal structures; modelling the movement of nematodes in soil and elucidating the mechanisms responsible (chemokinesis, chemotaxis); testing of the mathematical models with experimental data. The mathematical techniques to be employed will include analysis of nonlinear partial differential equations, numerical analysis of pdes and stochastic cellular automata.

The research involved is of a genuinely interdisciplinary nature. The appointed RA will be based in The Department of Mathematics, University of Dundee, but will also be part of the dynamic environment of the Centre for Nonlinear Systems in Biology. The Centre is a cross-disciplinary collaborative venture between the University, the Scottish Crop Research Institute, and Biomathematics and Statistics Scotland. In addition, there will be very close day-to-day collaboration with the Soil Plant Dynamics Unit at the Scottish Crop Research Institute. An RA1B responsible for the experimental work of the project has already been appointed.

Suitable candidates should possess a PhD in Applied Mathematics. A background of ODEs, PDEs, Nonlinear Dynamical Systems would be preferred. Willingness to work with experimentalists is essential.

Formal applications, including 2 copies of a full CV and names, addresses, telephone/FAX numbers of two academic referees should be sent to Personnel Department, University of Dundee, Dundee DD1 4HN, by 6th June.

Informal enquiries by e-mail, phone or FAX to Dr. M.A.J. Chaplain, Department of Mathematics, University of Dundee are very welcome.

University of Warwick

Mathematics Institute

Nonlinear Dynamics and Spectra of Molecules

Applications are invited for a 3-year EPSRC funded postdoctoral research assistantship to work with Dr. R.M. Roberts (Warwick) and Prof. J. Tennyson (University College) on "Nonlinear Dynamics and Spectra of Molecules".

The project aims to develop classical and semi-classical techniques for predicting and explaining the rovibrational spectra of small symmetric molecules. In particular, recent advances in the theory of symmetric Hamiltonian systems will be used to locate and analyse relative equilibria (ie `steady rotations'), periodic solutions and invariant tori in the phase space of classical molecular rovibrational Hamiltonians. Semi-classical methods will then be used to predict the energy levels and symmetry species of wavefunctions localised around these classical trajectories. The results will be compared with exact quantum calculations for specific molecules.

Applicants should have, or shortly expect to receive, a PhD in a relevant area of mathematics, physics or chemistry. Preference will be given to candidates with experience of one or more of the following:

The post will be available from June 1997. The appointment will be made on the RA 1A Scale (15,159 - 22,785 pounds).

Application forms and further particulars are available from the Personnel Office, University of Warwick, Coventry CV4 7AL, UK (Tel: (0)1203 523627), quoting ref: 38/A/96 (please mark clearly on the envelope).

Informal enquiries can be made to: Dr. R.M. Roberts, Department of Mathematics, University of Warwick, Coventry CV4 7AL, UK (e-mail: mark@maths.warwick.ac.uk).
