Dr. Alexandre Kukui from Laboratory of Physics and Chemistry of the Space Environment, the National Center of Scientific Research (CNRS), France was invited to visit LAP³ and the department of environmental science & engineering, Fudan University from November 15^th to November 28^th 2014. After postdoctoral position, he worked in CNRS, and is dedicated in ambient investigation and lab simulation using flow reaction tube of organic aerosol chemistry, especially atmospheric radical reaction process with mass-spectrometric techniques including chemical ionization mass spectrometry (CIMS). He made remarkable achievement atmospheric aerosol science (http://www.era-orleans.org/ERA-TOOLS/fiche-52.html).

On November 21^st, Dr. Alexandre Kukui delivered a presentation entitled OH· and H₂SO₄ Measurements by CIMS: Application for Atmospheric Chemistry Studies to the researches and postgraduate students of LAP3. He shared ambient research experience of OH· and ROx· detection, organic aerosol measurements, and radical chemistry kinetics analysis. The repost achieved good response.
