This site is a work in progress, but the basics are here...

The photo above was taken on the Ocean Drilling Program (ODP) drillship "JOIDES Resolution" when it was in Prydz Bay, Antarctica. That's me on the right.

My research interests include:
-
The evolution of the Antarctic ice sheets in the Miocene and Pliocene, by stratigraphy and provenance of ice-rafted debris and in marine sediment cores.
-
Sea level change in the Miocene and Pliocene, using carbonate records from the Bahama Bank.
-
Cretaceous Pacific paleoceanography from chert sequences.
- Paleomagnetism, including downhole magnetic logging, geomagnetic excursions and paleointensity.
