Paleoclimate, paleoceanography, proxy development and refinement

The main focus of my research is the understanding of the forcings and feedback mechanisms of hydroclimate and ocean circulation changes over centennial-to-orbital time scales.

I use marine sediments and cave deposits as climate archives and analyze stable isotopes and trace elements to reconstruct changes in climate and ocean circulation.

Opportunity: I am always looking for motivated undergrad students and grad students: If you are interested in working in my lab as an undergrad research assistant or PhD students, please contact me (
