We invite applications for a 1-year postdoc position available at CentraleSupélec (Université Paris-Saclay, France), with a flexible start date around March 2023.This is an experimental project in collaboration with Air Liquide R&D that aims at improving the geometry of the structured packings used in cryogenic distillation. See pdf attached for more information.

We are looking for a highly motivated candidate with a solid background in fluid mechanics, mechanics or physics.

Feel free to contact Hervé Duval (herve.duval@centralesupelec.fr) or Mikaël Wattiau (mikael.wattiau@airliquide.com) with any question.

The Physics Department at Emory University in Atlanta, GA, USA invites applications for a postdoctoral position in experimental soft matter and biological physics. The candidate will have the opportunity to work on a newly funded, highly interdisciplinary project centered on how bacteria and other microbes survive, grow, and interact in the air. The research is motivated by overwhelming evidence that airborne microbes critically impact everyday life, e.g., rainfall, disease spread, land fertilization, and food production. The candidate will help build and optimize acoustic levitators to grow bacteria on isolated particles in analog atmospheric conditions in the laboratory. A major goal of this research is to develop a new way to culture bacteria in the air and use this cutting-edge technology to understand the physiology, metabolism, ecology, and evolution of airborne microbes. The candidate will also be joining a collaborative research team, with physicists and microbiologists at Emory University, and Earth scientists at the University of Oregon.

Candidates are requested to send their curriculum vitae including a list of publications to Justin Burton at justin.c.burton@emory.edu and arrange to have 3 recommendation letters sent to the same address. Review of the applications will begin immediately, until the position is filled. The starting date for the position is flexible, from late Spring 2023 – early Fall 2023. Emory is an Affirmative Action/Equal Opportunity Employer. Therefore, women and minorities are especially encouraged to apply.

How to apply: Please contact Dr. Clément Narteau (narteau@ipgp.fr) & Laurie BARRIER (barrier@ipgp.fr) with “AEOLAND Postdoc application” in the subject line. Include a CV with a short research statement summarizing research experience. Application review will begin immediately and will be reviewed on a rolling basis until the position is filled.

Aeolian research is based on two main themes, dust and dunes, which are closely linked by transport laws derived from the physics of wind-blown particles. Nevertheless, as the time scales of dust emissions are many orders of magnitude shorter than those associated with dune field dynamics, the agreement between the corresponding transport properties remains poorly quantified. The objective of the AEOLAND project is to combine information on aeolian transport processes at different space and time scales (from 101 to 106 meters and years) to converge on consistent scenarios for sand and dust exchanges on continental surfaces, but also with the atmosphere. Such a transdisciplinary research approach aims to bridge the gaps between atmospheric dust (Laurent et al., 2005), dunes and aeolian landscape dynamics (Chanteloube et al., 2022). We propose to perform regional mass balances estimated from morpho-sedimentary markers to develop consistent scenarios for dust emissions and sand fluxes over large space and time scales that integrate the variability of meteorological events. These scenarios will be tested and parameterized at small scales against field observations and climate reanalysis outputs, so that they can be extrapolated over a wide range of intermediate scales on Earth and other planetary bodies.
The postdoc will integrate into an exciting team of researchers from two academic institutions (IPGP and LISA). The funding comes from the UnivEarthS LabEx program of Université Paris Cité, which is designed to set up a unique high-level teaching and training platform in the sciences of the Universe including comparative planetary research. The postdoc will lead two major efforts of the AEOLAND project: (1) the quantification of the impact of aeolian processes on arid environments from transport and morpho-sedimentary analyses at time scales ranging from those of dune systems (>102 yr) to that of landscapes (>104 yr), and (2) the cross-calibration the sand and dust transporting events over a wide range of time scales (101 s – 101 yr) using observations and numerical data. The postdoc will also engage in linking these two aspects, which is the cornerstone of the project, in order to promote this interdisciplinary research approach over the long term.
Ideally, the applicant should have: (i) a background in transport processes; (ii) experience in computer programing (Python, Matlab); (iii) independent research and teamwork skills; and (iv) communication skills. Priority will be also given to applicants with experience in any one, or a combination of, the following topics: expert knowledge of statistical analysis of geospatial and/or meteorological data; modeling of surface processes with geomorphic transport laws; application or development of remote sensing data and processing for Earth and/or atmospheric research; field-based data collection linked to surface processes; sediment transport, desert landscape and/or dune dynamics.
