Experience and Expertise

Dr. Lauritsen’s M.Sc. work was concerned with Monte Carlo simulation studies of phase transitions in non-equilibrium systems. The Ph.D. work focused on theoretical studies of scaling and dynamics of Laplacian growth, random lattices, Ising models and interfaces.

Until 1999, Dr. Lauritsen’s work covered various areas in non-equilibrium statistical physics and he initiated the investigations of boundary scaling in directed percolation and related models. He also contributed to the understanding of universality classes for self-organized critical models and their relation to interface depinning.

Since 1999 Dr. Lauritsen has worked on topics related to radio occultations, mainly advanced retrieval methods. Together with Dr. Michael Gorbunov, they carried out a detailed investigation of Fourier integral operator applications to radio occultation data and introduced the CT2 wave optics inversion method.

Since 2004 he has been the Project Manager of the Radio Occultation Meteorology Satellite Application Facility (ROM SAF, formerly GRAS SAF) under EUMETSAT which is a SAF responsible for the operational processing of radio occultation data from Metop and other satellites.

Dr. Lauritsen has published about 30 scientific articles in refereed, international journals (including 2 invited review papers), participated in over 100 conferences and workshops with many contributed talks, posters, and proceedings papers, and has about 10 invited talks and seminars at conferences and universities.

Research interests include: GNSS radio occultation processing, atmospheric multipath propagation, canonical transform inversion methods, and wave optics simulations.
