She has since worked on South Asian weather and climate variability.  Prior to joining the IRI Hannah worked at the International Energy Agency and the Scottish Government.

Research Interests

Hannah’s research interests include changing risks from climate extremes and the incorporation of long-term climate information into decision making. Her current research is focused on understanding the characteristics and changing risks of heat waves in Bangladesh and their health impacts. 

Role at IRI

Hannah joined the IRI in 2015 as an Earth Institute Fellow and a Fulbright Scholar, working in partnership with the Red Cross Red Crescent Climate Centre. She also conducts training for health and meteorology professionals in South Asia and the Caribbean on heat early warning systems and climate-health relationships.
