Welcome to the Ryan Lab! We study how the cryosphere and climate interact so that we can better forecast the societal consequences of Arctic warming in the 21st century. Most of our research involves remote sensing with satellites and uncrewed aerial vehicles (UAVs) but fieldwork is an important component as well. We are interested in a range of processes including snowfall, clouds, melt-albedo feedbacks, and supraglacial hydrology. The significance of our research is reflected by publications in journals such as Nature, Science Advances, Geophysical Research Letters, and Environmental Research Letters.

The group is led by Johnny Ryan who is currently an Assistant Professor of Ice and Climate in the Division of Earth and Climate Sciences at Duke University. Johnny grew up in Beverley, East Yorkshire where he attended Hymers College, Hull. He then studied Geography (BSc) at the University of Nottingham (2009-2012) before receiving an MPhil degree in Polar Studies at the University of Cambridge. Johnny completed his PhD in Geography at Aberystwyth University in 2018 and was a Postdoctoral Researcher at the Institute at Brown for Environment and Society for four years. He was an Assistant Professor of Geography at the University of Oregon (2021-2024) before starting his position at Duke.
