Stefan Kowalewski
During his physics studies at the University of Hamburg and the University of Canterbury, Stefan developed a strong interest in atmospheric physics, with special emphasis on radar remote sensing applications. As part of his diploma thesis, he was particularly concerned with microphysical properties in clouds and how these can be exploited to improve radar based precipitation measurements. During his PhD work at the institute of environmental physics [2010-2015], he had the opportunity to conduct research at Spitsbergen, where he set up passive remote sensing measurements to study the vertical dynamic coupling between the lower and middle atmosphere. His recent postdoc position within the glaciology section at AWI [2016-2017] gave him the exciting opportunity to continue his interest in radar remote sensing but also to broaden his field of view to the cryosphere. Stefan’s current research interests cover the surface mass balance of polar ice sheets and the potential contribution of remote sensing and in-situ observations to improve regional climate models.

Sally Woodhouse
Sally completed an undergraduate degree in physics and although she enjoyed the problem solving she wanted to study something more tangible that she felt was more applicable to everyday life. This led her to a masters in atmosphere ocean and climate which she thoroughly enjoyed. She was more interested in large scale climate dynamics during this course and when she saw her PhD topic advertised she thought it was ideal as it combined these interests with a general interest in the poles (perhaps a subconscious desire to be Lyra from His Dark Materials). On a broader scope she's interested in climate change, climate change policy, and how we can communicate science to politicians and the general public. [View Sally's FrostByte] -
Cheng You
Cheng is a PhD student in the department of meteorology, Stockholm University. His Bachelor degree is from the Nanjing University of Information Science and Technology (NUIST) and his MPhil Degree is from the Hong Kong University of Science and Technology (HKUST). His current research is mainly about the transport of warm air from southerly latitudes into the Arctic. The heat itself is of course important, but there are also other effects, such as the local effects from changes in static stability, in clouds and in winds, which happens as the air masses transform from the mild mid-latitudes to the cooler Arctic. Starting with direct observations and working with analyses of weather patterns, trajectories, satellite observations and models, his research is expected to improve our an understanding of these processes and their time scales, following air from south to north.
