Personal Overview
I earned my Ph.D. at the University of Hull, UK, in 1986. After spending time at The Ohio State University, The Smithsonian Tropical Research Institute, and Duke University, I joined the faculty of 澳门100%最准一肖一码, where I am a Professor. I have more than 30 years experience of working on the biogeography and paleoecology of tropical systems and every time I visit I learn something new about these wonderful settings. One of the most exciting things about these trips is to introduce undergraduates and graduate students to tropical biodiversity - for many this is a life-altering experience! By analyzing sediments from ancient lakes we gain insights into the history of landscapes and are able to reconstruct past ecosystems. My research focuses on the effects of past and present climate change on human and natural systems, some of our recent research topics include looking for the cause of the die-off of large mammals at the end of the last ice age, evaluating the ecological impacts of pre-Columbian occupants of Amazonia and the Andes, trying to establish the history of El Ni帽o events, and determining if previous interglacials in the Andes offer lessons for life under ongoing climate change. From these understandings we contribute to developing conservation strategies and in educating local communities about their history. My research group is keen to offer meaningful research opportunities to undergraduates. Undergraduates entering my laboratory are paired with graduate student mentors, and together we have a great track record of mentorship leading to our undergraduate workers presenting poster at scientific meetings and joining us as co-authors as we publish research findings in peer-reviewed scientific journals 鈥 both of which are great resume builders. I have published >200 papers on tropical ecology and climate change, and 2 books.
