Alexandra Tsekeri was born in Ioannina, Greece, in 1981. She received her B.Sc. in Environmental Engineering from the Polytechnic School of the Democritus University of Thrace (DUTH), Greece, in 2005 and her Ph.D. in Earth and Environmental Sciences from the Graduate School and University Center, The City University of New York (CUNY), USA, in 2011. Since 2012 she is a Postdoctoral Researcher at the Institute for Astronomy, Astrophysics, Space Applications and Remote Sensing (IAASARS) of the National Observatory of Athens (NOA) in Greece, working in the Remote sensing of Aerosols, Clouds and Trace gases (ReACT) group (https://react.space.noa.gr/).

Aerosol characterization using passive and active remote sensing techniques with focus on polarimetric data. Utilising novel inversion techniques, combine remote sensing observations with airborne and ground-based in-situ measurements, developing aerosol models and scattering databases, designing, optimising and operating remote sensing instruments for monitoring atmospheric aerosols (http://www.researcherid.com/rid/L-5503-2013).
