I am an atmospheric scientist and disaster geographer with interests in extreme weather and societal impacts. Our research group at NIU uses an interdisciplinary approach, employing techniques that span the social and physical sciences—from qualitative, survey-based research, to remote sensing and GIS, to the use of computer algorithms on remotely sensed data and numerical model output generated via high-performance computing. My scholarship characterizes the distributions of hazardous weather phenomena, their societal impacts, and how, ultimately, disasters will change in the 21st century. The goal is to supply government and industry stakeholders, policy makers, and the public with information necessary to mitigate disasters and build resilience in the face of rapid environmental and societal change.
