Position 1: Postdoctoral Research Scientist in glacier geophysics and ice sheet modelling

The Lamont-Doherty Earth Observatory, in the newly created Climate School of Columbia University, invites applications for a Postdoctoral Research Scientist (PDRS) to conduct research in the field of glacier geophysics and ice sheet modeling. The PDRS will use data from NASA Operation IceBridge and ROSETTA-Ice aerogeophysical campaigns over the Ross Ice Shelf, remote sensing (e.g. satellite altimetry from ICESat-II), and numerical modeling to better understand the vulnerability of Antarctic ice shelves due to channelized melting. They will have the opportunity to take a leading role in ice flow model development, with potential linkages to existing Pangeo projects and the NCAR climate model ecosystem. The successful candidate will join a project team led by Dave Porter, Jonathan Kingslake, Kirsty Tinto, and Renata Constantino at LDEO.

We want to attract a large and diverse applicant pool, so please consider sharing this opportunity with any networks that you think can help us achieve this.


Candidates should be recent recipients of a PhD in the earth sciences, geophysics, applied mathematics, ML/AI, or a similar field.

-- Experience with interpreting geophysical observations and/or geophysical fluid modeling is required.

-- Experience with processing and analyzing glacier geophysics observations (e.g., ice-penetrating radar, scanning lidar, etc.), ICESat-II data, or forward or inverse modeling of ice flow is desirable.

The appointment will be for one year with continuation pending funding and progress. The search will remain open until the position is filled.  Review of applications will begin on April 15th. Columbia University benefits are offered with this Officer of Research appointment.

Position 2: Postdoctoral Research Scientist in glaciology and machine learning

The Lamont-Doherty Earth Observatory (LDEO) of Columbia University invites applications for a Postdoctoral Research Scientist to conduct research in the fields of glaciology and climate data science. The successful candidate would join a project aimed at using machine learning and artificial intelligence to emulate ice flow physics in ice sheet models. The project team consists of Jonathan Kingslake (LDEO), David Porter (LDEO), Robin Bell (LDEO), and Laure Zanna (New York University). Our initial objectives include developing work flows to simulate ice flow over high-resolution basal topography with physics-based models and to emulate this process using machine learning algorithms.

This project is funded by a new science and technology center based at Columbia University called Learning the Earth through Artificial intelligence and Physics (LEAP). LEAP brings together geoscientists and machine learning experts to improve Earth system models and establish the new interdisciplinary field of climate data science. The successful candidate will engage with the interdisciplinary activities of the center by, for example, organizing and chairing LEAP working groups. They will also have opportunities to participate in LEAP's education and knowledge transfer activities.


Required experience/qualifications:

  • Either a PhD in geophysics with some experience of machine learning, or a PhD in machine learning/applied mathematics/statistics and a strong interest in applying machine learning to geophysics, specifically, glaciology 
  • Mathematical modeling
  • Scientific computing (e.g., MATLAB, Python, etc.)
  • Publishing peer-reviewed publications 

Desirable experience:

  • Modeling ice flow with physics-based models
  • Using machine learning algorithms to describe physical processes
  • Advanced scientific computing (e.g., scientific Python packages, high-performance computing, cloud computing, big data analysis, algorithm development)  

Appointment will be for 1-year with continuation pending progress and funding. 

The search will remain open for at least 30 days after the ad appears and will continue until the position is filled. 

Columbia University benefits are offered with this Officer of Research appointment.
