Postdoctoral Scholar in Applied Physics

 

School: Harvard John A. Paulson School of Engineering and Applied Sciences

Department/Area: Applied Physics

Position Description: Metasurfaces - subwavelength arrays of phase shifting elements - have emerged as a new tool for polarization optics. In particular, metasurface gratings can be used to simplify the optical architectures of polarimeters for a variety of scientific remote sensing applications. A postdoctoral scholar is sought to investigate the application and feasibility of metasurfaces to polarimetric imaging in support of two NASA-funded programs. The candidate will join a team of other postdoctoral scholars to mature this new polarimetric capability in collaboration with industry and NASA partners. The position presents an opportunity to study an early-stage nanophotonic technology from device-level physics to system-level optical design considerations and, ultimately, the scientific areas served.

 

Basic Qualifications: Ph.D. in optics, applied physics, physics, electrical engineering, or a related discipline

 

Additional Qualifications: Proficiency in laboratory optics. Previous experience in nanophotonics and cleanroom fabrication would be beneficial, but is not strictly required. History of work in polarization and optical polarimetry desirable.

 

Special Instructions: Please submit a current CV with publications listed, as well as a minimum of two reference letters.

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.
