Professor Sen Roy's research and teaching interests center on Climatology and GIS. Her work focuses on spatio-temporal patterns of precipitation across the Indian subcontinent, using advanced statistical GIS techniques to analyze trends in climatic variables. Research projects include: the impact of global teleconnections on the summer precipitation in India; trends in the occurrence of extreme precipitation events in India; diurnal patterns in the timing of winter precipitation in the United States; and the impact of cloud cover on diurnal temperature ranges. Her research has been published in The International Journal of Climatology, Physical Geography, Monthly Weather Review, Geophysical Research Letters, and Climate Research.
