Contrasting responses of functional diversity to major losses in taxonomic diversity.

Macroecology and Systematics

Probabilistic models of species discovery and biodiversity comparisons.

Selected Publications

Global biodiversity consists not only of the sum of taxonomic units such as species, but also their ecological or functional variety. These two components of biodiversity might be expected to rise or fall in tandem, but we find they are capable of strikingly independent behavior.
PNAS, 2018.

Estimates of species numbers are central to many analyses in fields ranging from conservation biology to macroecology and macroevolution. However, new species continue to be discovered and described at an uneven rate among regions and taxonomic groups, raising questions about the robustness of currently observed biodiversity patterns.
PNAS, 2017.

Teaching Roles

Increasing awareness of past and present biodiversity dynamics through teaching and mentoring inside and outside the classroom.

Undergraduate Mentorship

  • Matthew SchummLatitudinal patterns in functional and taxonomic diversity in marine bivalves and terrestrial birds. Matthew presented his work at SICB 2018 and is nearing submission of the paper now.
  • Safia Khouja“Bivalves Unhinged”: Biomechanical tradeoffs in hinge plate and muscle configuration. Safia will share her most recent results at GSA 2018, and has presented previous material at SICB 2018. Safia is now closing in on the final manuscript.
  • Sarah LeventhallTradeoffs in marine bivalve shape and size across latitude. Sarah successfully defended her thesis in Spring 2018 and is now a graduate student at UC Boulder.
  • McKenzie MandichRanked effects of heavy metals on marine bivalves in laboratory mesocosms. McKenzie, now an ESOP Fellow at ETH Zürich studying Biogeochemistry and Pollution Dynamics, has published her senior thesis in Marine Pollution Bulletin!

Instruction

I have taught in the following courses at UChicago:

  • Biological Evolution
  • Biostratigraphy and Sedimentology
  • Modern and Ancient Carbonate Environments
  • Environmental History of the Earth
  • Natural Hazards
  • Chemistry in the Atmosphere

Outreach

  • Jr. Science Café: Climate Clues – Developed and presented a 30-minute interactive session for middle school students at the Chicago Museum of Science and Industry on reconstructing past climates.
  • Career Day – Participating scientist at The Museum of Science and Industry’s Science, Technology, Engineering, and Mathematics Career Day.
  • Science Advisor – Brainstorming Science Fair Ideas with high school students at the Field Museum of Natural History
  • Science 360: Earthquakes! – Designed and implemented a 30-minute interactive session for the general public on the science behind earthquakes. The show played at the Morehead Planetarium and Science Center for several years.
  • Carolina Science Café – Coordinated talks with University of North Carolina scientists to discuss their research with the general public at the Morehead Planetarium and Science Center.
