linebreak

I am a cryospheric scientist and modeler focused on interactions between ice and climate. I incorporate remote sensing and in situ measurements with global climate models (e.g. NASA GISS GCM) and regional climate models (e.g. MAR RCM) and ice dynamics models (e.g. ISSM) to study ice-climate interactions, particularly interactions between climate and polar ice sheets, with the goal of understanding the future impact of climate change on sea level rise.
