Faculty Overview
Dr. Bregy’s research interests take an interdisciplinary approach to reconstruct and understand changes in climate, hazards, and extreme events during the Quaternary and Common Era (though he is more than happy to go back further in time). While he uses many different paleoclimate proxies, he primarily relies on sedimentological, dendrochronological, and isotopic techniques for climate reconstructions. His research on paleohurricanes is largely focused on understanding changes in tropical cyclone frequency and intensity, long-term tropical cyclone–climate interactions, different tropical cyclone hazards (i.e., storm surge and precipitation), and developing novel proxy techniques for paleotempestology. This information can be used to prepare for ongoing and future changes in tropical cyclones in response to anthropogenic climate change. In addition to paleotempestology, he works on reconstructing hydroclimates, atmospheric and oceanic circulation patterns, and other coastal/hydrologic hazards (i.e., tsunamis, floods, sea-level change).
