My research deals with understanding the response of Northern Hemisphere ice sheets to long-term climate variability and their importance for understanding the long-term significance of recent anthropogenic change. The main goal of my postdoctoral position at Charles University is to re-create the pattern of deglaciation of the North American Ice Sheet Complex from ~25,000 years ago to present-day using geomorphology, chronology and paleoenvironmental records.
