Harvard CMB Group Postdoctoral Fellowships
Review begins Dec 1, 2019
The Harvard CMB group invites applications for two Harvard Postdoctoral Fellow positions to pursue research related to cosmic microwave background measurements with the BICEP Array telescopes, the South Pole Observatory, and CMB Stage 4. The multi-institutional BICEP program produces extremely deep maps of polarization of the CMB at multiple frequencies from the South Pole, measuring gravitational lensing and galactic foregrounds and placing leading constraints on primordial gravitational waves. The BICEP Array project is upgrading the current program with new instrumentation to include over 30,000 detectors and five frequency bands, to be deployed and operated over the next five years. The program will continue to produce maps with groundbreaking sensitivity, while validating technologies and methodologies essential to Stage 3 and Stage 4 CMB science goals. A major focus is analysis of current and upcoming BICEP data, including joint analysis with data from the 10m South Pole Telescope and external datasets, to continue to improve lensing measurements, component separation, and constraints on primordial cosmology, as well as forecasting and design optimization for future efforts of the South Pole Observatory and CMB Stage 4.

Successful candidates will play a variety of leading roles spanning receiver and telescope design, deployment and operation, real time control code, optimization of data reduction and simulation on leading HPC infrastructure at Harvard and NERSC, and development of high-level analyses for survey combination and cosmological interpretation. Applicants should indicate which roles best match their experience and interest. Successful candidates will actively represent this research at conferences and take leading roles in preparation of results for publication. The postdoctoral fellow positions offer a highly competitive salary, an independent research fund and an allowance for relocation expense. The position will be renewed annually based on satisfactory performance, for an expected total length of three years. Joint appointments with collaborating institutions are possible and may be considered on a case by case basis.

Tenure-track position at the University of Wisconsin-Madison
For full consideration, apply by Dec 1, 2019
We welcome all theoretical physics applicants who can take advantage of the anticipated unprecedentedly large influx of disparate, complex cosmological data to advance the frontiers of computational/theoretical cosmology.Learn more
