Ph.D. position in Biogeology

on “The effects of bioirrigation on benthic foraminifera”(vacancy number 72082)

The Darwin Center for Biogeology is a virtual Dutch research institute, which aims at performing cutting-edge science in the central field of Biogeology where Biology and Earth Sciences meet. Its research mission is to understand the functioning of global, regional and local ecosystems, focusing on change and feedback at all time scales in and between biotic and abiotic components of a changing Earth. The Center is partially funded by the Netherlands Organisation for Scientific Research (NWO),

Recently, a new research programme was started in close collaboration between Utrecht University (UU) and the Netherlands Institute of Ecology (NIOO-KNAW), entitled:

Niche engineering and the evolution of biogeochemical cycles through time

Modern marine environments are characterized by complex faunal communities living in the sediment with densities and diversities that vary depending on sediment type, availability of oxygen and organic matter load arriving at the sea bottom. Some species play an extraordinary role in creating suitable environments for other taxa to live in. These keystone species, for example deep burrowing lugworms, are regarded as niche engineers. Through geological history, origination of such niche engineers is hypothesized to have lead to sudden bursts in evolution of other infaunal taxa.

The programme embraces two Ph.D. positions. Currently, we are looking for a candidate for the Ph.D. position at Utrecht University concerning the project:

The effects of bioirrigation on benthic foraminifera

Project description:

The aim of this project is to study the effects of the presence of various types of niche engineers on the surrounding meiofauna, in particular the foraminiferal population, and on biogeochemical cycling. Bioturbation, burrow ventilation, bioirrigation and grazing are activities that may have a significant impact on the vertical distribution of benthic foraminifera in marine sediments. Alternatively, foraminifera seem to have a considerable impact on the bacterial population and, consequently, the biogeochemistry.

The project will involve laboratory experiments with the coupled system biogeochemistry-bacteriaforaminifera in sediment cores with different imposed biogeochemical conditions, and with or without artificial bioirrigation. It also involves field sampling of marine sediments (Wadden Sea).

The project will be supported by ongoing modeling work within the research groups of Stratigraphy & Paleontology at Utrecht University and Microbial Ecology at NIOO-KNAW.

Qualifications:

We are looking for a highly motivated individual with excellent communication skills who is interested in interdisciplinary research combining various fields of biogeology. The candidate holds an M.Sc. or equivalent degree in an appropriate field.

Terms of employment:

We offer a full-time Ph.D. position for 4 years, with monthly salary starting at € 1956,- in the first year to € 2502,- in the last year of appointment. We also offer a pension scheme, a collective health insurance and flexible employment conditions. Conditions are based on the Collective Employment Agreement of the Dutch Universities and are supplemented with a holiday allowance of 8 % per year and a year-end bonus of 3%.

Ph.D. position on the rheology of planetary ice and tectonics of icy moons

We seek a candidate to fill a Ph.D. position in the Department of Earth Sciences at Utrecht University.

Project title:

The role of grain size in the rheology of planetary ice

Project description:

The icy surfaces and inferred internal structures of icy planets and moons of our solar system show a remarkable diversity, and form an important basis for comparative planetary research. Various thermophysical modeling studies have already been performed, aiming to understand composition, structure, origin and evolution of the icy planets and moons, including conditions for life. Large-scale dynamic processes (e.g., convection) are implied for the solid interiors of the icy bodies, so the modelscritically depend on the rheological descriptions implemented to describe the flow of ice.

One aspect of ice rheology that has received increased attention of late is the role of grain (crystal) size and its evolution during deformation. Extensive work on solid state flow of rocks has shown that quantitative understanding of such grain size evolution is essential if laboratory derived rheological laws are to be reliably extrapolated to natural (extreme) conditions. This also applies to the case of ice, but has not been accounted for to date.

The objectives of the project are:

a) to develop a state-of-the art microphysical model for water ice including microstructural evolution and multiple creep mechanisms,
b) to test this model against data that are to be obtained from laboratory deformation experiments on ice, to be performed by the Ph.D. student in collaboration with co-workers at MIT/Cambridge MA and USGS/Menlo-Park CA, U.S.A., and
c) to assess the large scale implications of the results by building the obtained mechanism-based description into numerical models of tectonic processes on icy moons, with particular focus on tidal deformation of planetary moons, in collaboration with researchers from Delft University of Technology.

Funding for this project is provided by the Netherlands Organization for Scientific Research, through the Dutch National User Support Programme Space Research.

Qualifications:

We are looking for a highly motivated individual with a strong background and excellent communication skills. The candidate has a broad interest in Earth materials research in a laboratorial setting. The candidate is familiar with numerical modeling, preferably but not necessarily in the context of rheological modeling. Proficiency in at least one modern programming language is a requirement.

The candidate holds a recent M.Sc. or equivalent degree in Geology, Geophysics, Materials Science, Solid State Physics, or a related field.

Terms of employment:

We offer a full-time Ph.D. position for 4 years, with gross monthly salary starting at € 1956,- in the first year to € 2502,- in the last year of appointment. We also offer a pension scheme, a collective health insurance and flexible employment conditions. Conditions are based on the Collective Employment Agreement of the Dutch Universities and are supplemented with a holiday allowance of 8% per year and a year-end bonus of 3%.

Further details:

The project will be carried out within the Experimental Rock Deformation group at Utrecht University’s Institute of Earth Sciences, in collaboration with researchers at MIT and USGS in the U.S.A and at Delft University of Technology. For further details, please contact dr. Hans de Bresser at j.h.p.debresser@geo.uu.nl.

PhD Fellowship in Modelling of Nanoparticle Formation - Swinburne University of Technology

Swinburne University of Technology is a seeking a suitable qualified student from an engineering and/or science background to undertake post-graduate study to develop models for predicting the formation and growth of nanoparticles from supersonic quenching of gases.

Supersonic quenching is a technology for producing significant quantities of nanoparticles in a controlled way. Various nanoparticles are being used already in advanced materials and growth in their use will require well-controlled materials processing techniques to be developed.

Recent experimental and modelling work using supersonic nozzles suggests that the range of particles sizes produced can be readily manipulated through changes to geometry and associated chemical conditions.

The main tasks associated with the project are: review of current designs for producing nanoparticles from supersonic quenching, review of nucleation and growth kinetics, development of one dimensional models for predicting particle growth in a defined temperature and flow regime, incorporation of one dimensional models into multi-dimensional models and validations of these models against existing experimental data.
