Dr. Mixtli Campos

Biography

Postdoctoral researcher at the Centre for Research into Atmospheric Chemistry (CRAC) at University College Cork. I work on the development of optical cavities (Cavity Enhanced Absorption Spectroscopy and Cavity Ring-Down Spectroscopy) for the new Irish Atmospheric Simulation Chamber. The instruments will be used to study kinetics and mechanisms of VOC oxidation under atmospheric conditions. Previous work involved satellite data analysis, construction of CEAS instruments, R2PI-VMI studies of vibrational predissociation dynamics, computations of excitation energies using QChem, and study of ozonolysis of alkenes using CRDS.
