Lab members and collaborators

Ling worked on two projects: (1) assessing the population size of the North Atlantic right whale, one of the most endangered large cetacean species, and (2) estimating the number of pulses in a mass extinction. She presented a poster at the Geological Society of America annual meeting (Minneapolis, 2011) and the Sigma Xi poster session (Swarthmore, 2011). She is a co-author of two GSA abstracts, a paper in review for Paleobiology, and another currently in preparation. Ling is majoring in math and economics. At left, she explains her poster to Jason Downs.

Sally did an independent study on extinction selectivity in mass extinctions. She majored in biology and medieval studies and is currently a graduate student in ecology and evolutionary biology at the University of Kansas.

Aaron and Brendan worked on confidence intervals for estimating the duration of a mass extinction. They presented a poster at the Geological Society of America annual meeting (Denver, 2010) and the Sigma Xi poster session (Swarthmore, 2010). They are co-authors of a 2012 paper in Paleobiology and a GSA abstract. Brendan majored in math with a minor in physics and currently works in consulting. Aaron majored in math and engineering and is currently a graduate student in statistics at the University of Washington.

Brianna worked on the evolution of body size in foraminifera and the effect of mass extinctions and recoveries on size trends. She is the lead author of a paper in Paleobiology and a GSA abstract. Brianna earned her PhD in history of science at Stanford University and is now a Visiting Scholar in the Department of History at Stanford.

Heidi worked on two projects: (1) confidence intervals for estimating the duration of a mass extinction, and (2) visualizing complex datasets using Chernoff faces. For the first topic, she presented a poster at the Geological Society of America annual meeting (Portland, 2009) and is the co-author of a 2012 paper in Paleobiology and two GSA abstracts. For the second topic, preliminary results from our work were presented by Steve at the Harvard Quintessential Contributions celebration, and further work is ongoing. Heidi majored in cognitive science with a minor in statistics and is currently a M. Arch student at the Taubman College of Architecture and Urban Planning of the University of Michigan.

Dasol worked on confidence intervals for stratigraphic ranges when recovery potential is non-uniform. He presented posters at the Geological Society of America annual meeting (Houston, 2008) and the Sigma Xi poster session (Swarthmore, 2008). He is a co-author of two abstracts and a paper currently in preparation. Dasol majored in math and computer science and currently works in investment management.

Geoffrey worked on Markov Chain Monte Carlo algorithms for estimating extinction levels in the end-Permian extinction. He presented posters at the Geological Society of America annual meeting (Houston, 2008) and the Sigma Xi poster session (Swarthmore, 2008). He is a co-author of an abstract and a paper currently in preparation. Geoffrey majored in math and computer science and is currently a graduate student in computer science at Brown University. At left, he explains his poster to Tom Rothfus.

Mike worked on Markov Chain Monte Carlo algorithms for estimating extinction levels in the end-Permian mass extinction. He presented posters at the Geological Society of America (Philadelphia, 2006), the Joint Statistical Meetings (Salt Lake City, 2007), the Smithsonian-UPenn Geobiology Symposium (Washington, DC, 2007), and the Sigma Xi poster session (Swarthmore, 2007). He is the co-author of two abstracts and a paper currently in preparation. Mike majored in math with a minor in English. He is currently a graduate student in statistics at the University of Washington.

David worked on confidence intervals for stratigraphic ranges when recovery potential is non-uniform. He is a co-author of a paper in Paleobiology and another paper currently in preparation. David majored in math with a minor in linguistics. He earned an MS in mathematics from the University of Chicago and currently works as a predictive modeler in the insurance industry.
