Dr. Wade's research interests encompass the Cenozoic palaeoceanography and the palaeoecology of calcareous microfossils. She uses microfossils and their chemistry to determine patterns of evolution and extinction, ancient marine temperatures, productivity levels, global ice volume and sea level fluctuations. Her research has been international in scope, involving fieldwork in Europe, Africa, and the Caribbean/Gulf of Mexico. She participated as a shipboard scientist on Ocean Drilling Program Leg 199 (2001) and Integrated Ocean Drilling Program Expedition 321 (2009), as well as a site survey cruise (2009), onshore drilling by the International Continental Scientific Drilling Program at Chesapeake Bay Impact Structure (2005) and the Tanzania Drilling Project (2004). Currently she is engaged in a number of research projects focusing on Paleogene climate change from excellently preserved planktonic foraminifera to reconstruct sea surface temperatures across critical boundaries in Earth history. Related to her research in palaeoceanography, is the high resolution refinement and calibration of Paleogene planktonic foraminiferal biostratigraphy, and determining the biotic response to climatic events. From 2005 Bridget has been Chair of the Paleogene Planktonic Foraminifera Working Group, part of the International sub-commission of Paleogene stratigraphy. Bridget was recently awarded The Geological Society Wollaston Fund (2012), and has previously received the Alan Higgins Award from The Micropalaeontological Society (2011); the Hodson Award from the Palaeontological Association (2008) and a CAREER Award through the National Science Foundation's (NSF) Faculty Early Career Development (CAREER) Program (2009).
