Biography

Hello and welcome!

My name is Hamed Pourkhorsandi. I am a geologist with expertise in studying meteorites. I did my doctoral studies in Aix-Marseille Université/CEREGE in France with a focus on classification and terrestrial weathering investigation of hundreds of meteorites from hot deserts. Before that, I did a B.Sc. in geology in Payam-e Noor University, and a M.Sc. in petrology in University of Tehran.

At the moment as a Marie-Curie@ULB COFUND fellow at Laboratoire G-Time of the Université Libre de Bruxelles (Belgium), I am working on the elemental and isotopic composition of the earliest solids formed in the solar nebula using state-of-the-art analytical methods.

Besides working in man-made laboratories, I am also experienced in meteorite recovery from different hot deserts, including the Atacama, Sahara, Lut, and Antarctica.

In addition to meteoritics and cosmochemistry, I am also interested in working on new isotopic system to be used in solving geochemical mysteries…

Of course as a petrologist, I am always interested in working on terrestrial rocks and testing new analytical methods on them!

If you are conducting any study which requires geochemical analyses, I would be interested to discuss. I am open to new collaborations…

Please check my website and if you have any questions don’t hesitate to contact me.

Regards,

Hamed
