Work experiences and research interests
At the University of Franche-Comté, France, I was mainly involved with airglow image processing. I also developed a mobile acquisition system to study the near-infrared OH emission for nighttime measurements from Alpine observatories. My research dissertation focused on image processing techniques to study gravity waves: stars filtering, calibration, flat-fielding, unwarping, enhancement and localization of the waves, and determination of their propagation characteristics.
At Utah State University, I worked initially as a Post Doctoral Fellow in the Center for Atmospheric and Space Sciences (CASS), with Dr. M.J. Taylor. My research focused on the study of multiple airglow emissions (OH, OI, O2, Na) using all-sky CCD cameras. I developed a full image processing capability (filtering, 3D FFT, NURBS) for studying gravity waves. This software is currently used by students and researchers (including myself) for regular analysis our airglow gravity wave image data. I was also involved in the investigation of other atmospheric phenomenon including sprites and noctilucent clouds (NLC). I assisted in the development and maintenance of our CCD cameras and I have played a leading role in the organization of several measurement campaigns in Australia (DAWEX, 2001), Rarotonga, Cook Islands (2002), Sweden (MacWave 2003), and Brazil (Brazil Sprites 2002-2003 and 2006, SpreadFEx 2005, CNOF/S 2009).
In 2006, I took a visiting scientist position at INPE, Brazil, working with Dr. H. Takahashi on the analysis of the data obtained during the SpreadFEx 2005 campaign. I was also involved in sprite measurements and analysis with Dr. F.T. São Sabbas and in a new collaboration on NLC mapping with Dr. J. Stegman, from University of Stockholm.
In 2008, I returned to USU as a Research Scientist to lead the software development, testing and operation of an new Advanced Mesospheric Temperature Mapper (AMTM) system. I also led the installation at the South Pole Station (Jan 2010), subsequent servicing (2011 and 2012), and data analysis for austral winters (2012 to date). I recently set up a second AMTM at ALOMAR, Norway for complementary Arctic studies and am currently involved with the development of a new version of the AMTM for the GV aircraft as part of the DEEPWAVE instrument development program.
