Early Career Events
The Early career event program provides opportunities for less senior scientists to network and learn from volunteers from the community.
These events are all being planned by our exhibitors. To find out more information, visit them on their booths.
Pre- and post-conference field trips

I am physical chemist and use oxygen triple, sulfur quadruple isotopes and concomitant isotope anomalies to understand chemical and photo-chemical processes in the atmosphere. The isotopic signature preserved in rocks, ice and aerosols allows me to understand intricate interactions between atmosphere-hydrosphere-geosphere and biosphere. I have used ALH84001 (the most famous meteorite once cosidered to carry relics of life from Mars) and NWA70034 (Black Beauty) to constraint hydrosphere and CO2 cycle on Mars ~ 4.2 billion years ago. Meteorites are amazing gifts of nature to curious minds and I enjoy revealing the mysteries preserved in those rocks. I use sulfur and oxygen isotope anomalies to understand the hydrosphere and atmosphere interactions on earth and how high resolution record can shine light on the coupling between all spheres (atmo-hydro-geo-bio) as each one leaves its isotopic fingerprints in the aerosols that are transported to the stratosphere and preserved in the ice core records.Note: abstracts are only listed if one of the following email addresses was provided when the abstract was submitted: email@example.com.
