Research Interests

My main focus is on paleoecology, especially paleocommunity ecology, change in ecosystem structure over time, and patterns of change in marine diversity over time. More specific topics include:
   1) Utilization of ecospace and change in ecosystems over time
   2) The influence of ecospace utilization on diversity
   3) Distinguishing biological signals from taphonomic noise in fossil assemblages
   4) The varied nature of mass extinction events
   5) The implications of periodicity signals detected in diversity over time
   6) The interaction between origination and extinction in controlling diversity
   7) The asymmetry of trends in origination and extinction over time within taxa
