Job Announcement

Young, modern, and research oriented... the University of Potsdam has firmly established itself within the scientific landscape since its founding in 1991. Nationally and internationally renowned scientists teach and perform research here at Brandenburg largest university. The University of Potsdam is successful in acquiring third-party funds, delivers outstanding performance in technology and knowledge transfer, and has a very service-oriented administration. With about 20,000 students studying at three campuses - Am Neuen Palais, Griebnitzsee and Golm - the University of Potsdam is a prominent economic factor and engine of development for the region. The University of Potsdam has a total of about 2,750 faculty and staff members and is located in one of Germany most scenic areas.

innoFSPEC Potsdam, the Innovation Centre (ZIK) for fibre-based Spectroscopy and Sensing, is a joint initiative of the Physical Chemistry Group at the University of Potsdam (UPPC) and the Leibniz Institute for Astrophysics Potsdam (AIP). Subject to the grant approval decision UPPC invites applications for:

2 Postdoctoral Scientist/Wissenschaftliche/r Mitarbeiter/in

(40 hours per week = 100 %)

or

PhD Student /Doktorand/in

(20 up to 26,7 hours per week 50-67 %) positions

Requisition No.: 157/2017

The salary is determined by the collective bargaining agreement for public employees in Germany (TV-L 13 Ost). These are temporary positions up to 3 years.

innoFSPEC has set out to explore new frontiers in fiber-optical chemical sensing and multichannel spectroscopy. innoFSPEC provides excellent experimental facilities in a thriving interdisciplinary environment. Successful candidates will join the Research Group Innovative Fiber-Optical Sensing as soon as possible. The project will focus on the experimental analysis of optical properties of highly scattering and polydis-perse liquid dispersions consisting of particles or droplets. More details about the ZIK innoFSPEC can be found under www.innofspec.de.

Candidates should have a Diploma, Master or PhD in chemistry (Chemie), physics (Physik), applied mathematics (Angewandte Mathematik), engineering (Inge-nieurswissenschaften), or a related discipline, including experience in one or more of the following fields:

Laser spectroscopy and optical sensing

Light scattering

Fibre-optical instrumentation and photonics

Radio frequency electronics

 

 

 

Postdoctoral position on debris disks

 

The Astrophysical Institute and University Observatory (AIU) of the Friedrich Schiller University, Jena, Germany, is seeking candidates for a postdoctoral position.

The position is to work in the Research Unit FOR 2285 ``Debris Disks in Planetary Systems``, newly established by the German Research Foundation (DFG). The successful candidate will join the theory group at the AIU and will work for the Research Unit`s project P3 ``Origin of the warm and hot dust and planetary system architecture``. The project goals are to obtain improved statistics for the occurrence rate and parameters of warm and hot dust disks, to work out plausible scenarios for the origin of the observed warm and hot dust, to derive constraints on planetesimals and planets and the overall architecture of the systems, and to make suggestions for future observational tests.

The postdoc will benefit from close collaboration with other projects of the Research Unit running in Jena, Braunschweig, Hamburg, and Kiel. The position is for three years and can start at any time, but no later than in the early 2016. The salary is standard for postdoc positions in Germany (TV-L E-13 of the German federal public service scale) and includes a number of social and family-related benefits.

 

The applicants should have a strong educational record and hold a doctoral degree or equivalent in physics or astronomy. Previous experience with astronomical research, preferrably with debris disk and/or exoplanet studies, would be a strong advantage. Applications as a single document in the PDF format should include a CV, a brief statement of research interests, and three names of reference. All applications received by September 30, 2015 will be given full consideration. The Friedrich Schiller University is an equal opportunity employer and explicitely encourages women to apply. Disabled persons with equal aptitude, competence and qualification will be given preference.

Two graduate student positions on debris disks

 

The Astrophysical Institute and University Observatory (AIU) of the Friedrich Schiller University, Jena, Germany, is seeking candidates for two graduate student positions.

The positions are to work in the Research Unit FOR 2285 ``Debris Disks in Planetary Systems``, newly established by the German Research Foundation (DFG). The successful candidates will join the theory group at the AIU and will work for one of the following two projects.

 

In the first project (P1, ``Collisional modeling of resolved debris disks``), we plan to extend our knowledge of planetary systems harboring debris disks with the help of state-of-the-art collisional models. Such modeling is a powerful tool to decipher information encrypted in the observed dust and to connect the dust to its parent bodies, directly unobservable planetesimals. Constraints can be placed on locations and masses of planetesimal belts, their size and radial distribution, degree of dynamical excitation, material properties, etc. The graduate student is expected to refine our collisional code, incorporate recent advances from theory and laboratory work, and use the code to study a suite of resolved debris disks.

 

The second project (P2, ``Sculpturing of debris disks by planets and companions``) aims at modelling of observed asymmetries in debris disks. Common disk features include, for instance, sharp radial boundaries, eccentric offsets, and azimuthal asymmetry. All these are signposts of underlying perturbations that shape the disks. A variety of possible mechanisms have been put forward to explain these phenomena. Many involve the gravitational influence of suggested but yet unseen planets and companions. To study this fascinating connection, the graduate student will combine the dynamical treatment (that describes these perturbations) with the collisional treatment (that describe the dust production) to construct a single numerical model.

 

Both students will work in close collaboration with other projects of the Research Unit that will provide key ingredients for the collisional models and calculation of observables. They will greatly benefit from the expertise available in the Unit, in general, and our group, in particular. The positions are for three years and can start at any time, but no later than in the early 2016. The salary is standard for postdoc positions in Germany (1/2 TV-L E-13 of the German federal public service scale) and includes a number of social and family-related benefits. The applicants should have a strong educational record and hold Master degree or equivalent in physics or astronomy. Previous experience with numerics and astronomical research, preferably with debris disk and/or exoplanet studies, would be an advantage.

 

Applications as a single document in the PDF format should include a CV, a brief statement of research interests, and two names of reference. All applications received by September 30, 2015 will be given full consideration. The Friedrich Schiller University is an equal opportunity employer and explicitely encourages women to apply. Disabled persons with equal aptitude, competence and qualification will be given preference.
