About Me

I am a polar climate scientist with broad-ranging interests in ice and climate.

I'm based at the Alfred Wegener Institute in Bremerhaven, Germany, where I lead a junior research group on Southern Ocean and Antarctic sea ice evolution (SO-ASE). We aim to improve understanding of the Antarctic climate, sea ice and ocean system using models and observations.

I also teach at the University of Bremen in the Institute for Environmental Physics, where I have been awarded the title of professor.

Previously I was an Associate Research Scientist at NASA Goddard Institute for Space Studies and Columbia University, a postdoc at the University of Washington, and PhD student at NIWA and Victoria University of Wellington in New Zealand.

Don't hesitate to contact me directly (lettie.roach[at]awi.de). I don't currently have open PhD or postdoc positions, but am happy to accept Masters thesis applications via email.
