Howard J. Spero, Ph.D.

Spero CV

Research focuses on the biological and environmental parameters that affect the stable isotope and trace metal geochemistry of the shells of recent and fossil organisms; paleoclimatology, marine micropaleontology, and paleoceanography. An ongoing multi-year field research program involving undergraduate and graduate students has been studying living planktonic foraminifera in the Southern California Borderland and the Caribbean. The results of this study are being used to interpret fossil foraminifera stable isotope data from Indian and Atlantic Ocean deep sea cores in order to reconstruct paleoenvironmental sea surface temperatures, nutrient levels and CO₂ concentrations during the Pleistocene.

Dave Winter, Lab Manager
dave.winter@geology.ucdavis.edu

Dave joined the lab in February of 2000 with 30 years experience managing stable isotope facilites at UCLA and the University of South Carolina (they only recognize one USC there). He enjoys working with students and keeping professors in line.

Ann Russell, Associate Research Scientist
russell@geology.ucdavis.edu
Russell CV

Ann Russell's research focuses on developing and applying trace metals and stable isotopes in biogenic calcite as proxies of ocean pH and temperature. Her ultimate goal is to quantify changes in ocean carbonate chemistry and explore the linkages between these changes and atmospheric carbon dioxide concentration, ocean circulation, and climate change

Tessa M. Hill, Ph.D.
tmhill@ucdavis.edu
Hill CV

Tessa Hill joined the lab as a UC President's Postdoctoral Fellow in October 2004. She received her PhD at UC Santa Barbara (2004), where she studied forcing mechanisms of rapid climate change in the late Quarternary.

Mattew Schmidt, Ph.D. Candidate
schmidt@geology.ucdavis.edu
Schmidt CV

After completing a BS in Geology at Vanderbilt University and a MS in Geology at the University of South Florida, Matthew started work on his PhD in 2000. During his time in the Geology Department here at UCD, Matthew has recieved two Ocean Drilling Program Schlanger Fellowships to help fund his research on sea surface salinity change in the North Atlantic over the past four glacial cycles. He plans to graduate this summer and to continue his research with the NOAA Climate & Global Change Postdoctoral Program.

Kathryn Rose, Graduate Student
rose@geology.ucdavis.edu
Rose CV

After a summer of enjoying jersey fresh tomatoes, starry nights and research work on the R/V Knorr, Kathryn Rose joined the Spero lab as a master’s student in the fall of 2004. She received her bachelor’s degree in geology at Rutgers University (spring 2004) and enjoys the simple pleasures in life while growing, learning and adjusting- attempting to enjoy the passage of time.
