Research Interests:

• Historical Geology, Paleontology, Paleoceanography, Paleoclimatology.

• Evolutionary processes and the history of marine microfossil communites

• Classification and taxonomy of benthic foraminifera

• Biochronology of marine microfossils and calibration of zonal and stage boundaries to the Geomagnetic Polarity Time Scale

• Biostratigraphy of the North Atlantic and its marginal seas.

• High-latitude biostratigraphy and its correlation to standard, low-latitude biochronology

• Problems in Tethyan Paleobiogeography.and stratigraphic correlation.

• The evolution of Cretaceous-Cenozoic climate and the timescales of Global Change.

• The use of benthic foraminiferal assemblages for paleoenvironmental analysis:

• The development of the general circulation of the Atlantic Ocean from the Late Cretaceous to the Recent.

• North Atlantic sediment drifts, and the onset of thermohaline circulation in the world ocean

• Cretaceous/Tertiary, Eocene/Oligocene, and Miocene/Pliocene boundary problems.

• Disequilibrium processes in benthic marine communities.

• Paleobathymetric models and quantitative paleoecology (community structure).
