Postdoctoral Fellow in Modelling and Machine Learning for LSST (3)

Stockholm University

Sweden

January 15, 2022

Description

atthe Department of Physics. Closing date: 15 Januari 2022.

The Department of Physics is one of the biggest departments within the Faculty of Science and supports a broad range of basic research in experimental and theoretical physics. It has about 250 employees of which 95 are PhD students. Many have been internationally recruited. The Department is part of the AlbaNova University Center, which apart from the Department of Physics houses the Department of Astronomy, the Physics Departments at the Royal Institute of Technology (KTH), and the Nordic Institute for Theoretical Physics (Nordita).

The Department of Physics and Stockholm University is affiliated to Stockholm Dual Career Network (SDCN) that supports expat partners with professional events, career-related advice and by building a social network in their new hometown. https: // www. sdcn.se/

Project description We are searching for outstanding individuals to conduct original research on computational modelling and/or advanced machine-learning for analysis of photometric datasets. We are also looking for theoretical physicists interested in foundational understanding of deep learning methods. Up to three positions are available.

The successful applicants will be part of the European Research Council Advanced Grant CosmicExplorer project, led by Hiranya Peiris. The positions are also partially funded by an award from the Goran Gustafsson Foundation. The work will prepare the path for the Vera C. Rubin Observatory's Legacy Survey of Space and Time (LSST), and will be carried out within the LSST Dark Energy Science Collaboration.

The successful candidates will be part of the Oskar Klein Centre for Cosmoparticle Physics (https:// www. okc.albanova.se/) in Stockholm, a rich scientific environment that comprises more than a hundred researchers working in both theory and experiment in the fields of astronomy, astrophysics and particle physics at both Stockholm University and the Royal Institute for Technology. The OKC hosts a vibrant research program on dark matter, dark energy, transient and multimessenger astrophysics, galaxy evolution, structure formation, and related particle physics questions.

Postdoctoral associates are also welcome to participate in Scientific Programs at Nordita, the Nordic Institute for Theoretical Physics, which bring together groups of leading experts to work on specific topics for extended periods.

Main responsibilities The positions involve original research in cosmology, broadly related to testing fundamental physics with LSST. Daily responsibilities will include computational modelling/simulation, developing and applying novel statistical and machine learning techniques, writing production-level code for analysis of LSST data and precursor datasets, and/or preparing for the coming LSST data by analyzing precursor surveys.

A different research profile can include the theoretical investigation of deep learning, e.g., using effective field theory techniques. Experts in other relevant fields, especially those with experience in explainable artificial intelligence, are also welcome to apply.

Qualification requirements Postdoctoral positions are appointed primarily for purposes of research. Applicants are expected to hold a Swedish doctoral degree or an equivalent degree from another country.

Assessment criteria The degree should have been completed no more than three years before the deadline for applications. An older degree may be acceptable under special circumstances, which may involve sick leave, parental leave, clinical attachment, elected positions in trade unions, or similar.

IIn the appointment process, special attention will be given to research skills in one or more of: cosmological and astronomical data analysis, statistics, programming, numerical or machine-learning modeling, and theoretical physics expertise.

Terms of employment The position involves full-time employment for a maximum of two years, with the possibility of extension for one year. Start date by 1 Oct 2022 or as per agreement (funding is available to start immediately).

Stockholm University strives to be a workplace free from discrimination and with equal opportunities for all.
