Alain Plattner CV


Welcome to the website of the geophysics group led by Alain Plattner.

We are part of the Department of Geological Sciences at the University of Alabama, Tuscaloosa.

You can find more information about current and past research on the research page. The publications page contains links to pdfs of published articles. You can install Matlab/Octave functions to construct and plot vector Slepian functions using the installation scripts and demo functions on this Git repository, which will automatically download the software from Slepian_alpha through Slepian_hotel, obtain the data files from Frederik Simons' repository, and setup the folder structure. If you would like access to our most recent software that I used in our research on Mars then please send an email to Alain Plattner (amplattner (at) ua (dot) edu).

 

About me

I am interested in all aspects of numerical modeling and parameter estimation that arise within geosciences or related fields. My background is in computational geophysics (PhD at ETH Zurich) and mathematics (M.Sc. at University of Basel). Before my appointment at the University of Alabama I was an assistant professor at California State University, Fresno and a postdoctoral researcher at the Department of Geosciences at Princeton University working with Frederik Simons

My main research focus is on planetary potential fields such as magnetic and gravity fields, and on calculating these fields from satellite data. I am also interested in near-surface and applied geophysics, in particular in electrical resistivity tomography and ground penetrating radar.

My PhD at ETH Zurich was in the field of near surface geophysics. In this research I developed and implemented an adaptive algorithm for electrical resistivity tomography.


News

August 16, 2018

I am excited to have started my new position as assistant professor at the University of Alabama. This will allow me to greatly grow this research group including PhD students and postdocs.

I am also working on a Python-based graphical user interface GPR processing and visualization software that is scriptable and can automatically generate scripts while using the GUI. Here is the link to the software which is still under development: https://github.com/NSGeophysics/GPRPy


May 26, 2017

I just released the software package for planetary magnetic and gravity field inversions using a new type of vector Slepian functions. See the Software page for more details. The following repository contains installation scripts, instructions, and demos:

July 1, 2016

The near-surface Octave/Matlab programs developed for teaching near-surface seismics (Seism-O) and ground penetrating radar (GPR-O) are now available on NSGeophysics. See my software page for more information.


June 23, 2016

The Slepian GitHub wiki page https://github.com/Slepian/Slepian/wiki now contains detailed instructions and installation scripts for Windows, Mac, and Linux users.


 
 

Background figure

The figure in the background shows the radial component of Earth's crustal magnetic field up to spherical-harmonic degree 100 recovered from simulated radomly located noisy data points at varying satellite altitude only available over North America.
