Katie Collins, Jan Johan ter Poorten and I sampled nearly 580 lots of marine bivalves at the Florida Museum of Natural History early this November! We’re up to nearly 2500 sampled lots of bivalves in biv3d!


Team Bivalve (i.e., the Jablonski Lab) descends on Seattle for a series of talks at GSA. Times and places listed in the upcoming talks.


Katie Collins, Dave Dablonski, and I just finished our second trip to the Smithsonian to sample marine bivalves for biv3d! We’ve sampled nearly 50% of all marine bivalve genera! Up to 1 kilo-bivalves sampled as Dave likes to say.



The origin and maintenance of biodiversity.

Biogeographic Dynamics

Taxonomic, function, and morphological diversity through time and across space.

Bivalve 3D (biv3d)

Three-Dimensionalizing Marine Bivalvia


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.
Accepted In PNAS, 2017.

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.

Recent & Upcoming Talks

Many of these talks are a group effort, but should give an idea of the type of work I’m currently engaged in.

Teaching Roles

Undergraduate Mentorship

  • Matthew SchummLatitudinal patterns in functional and taxonomic diversity in marine bivalves and terrestrial birds. Matthew will be presenting his work at SICB in 2018!
  • Safia Khouja“Bivalves Unhinged”: Biomechanical tradeoffs in hinge plate and muscle configuration. Safia will be presenting her work at SICB in 2018!
  • Sarah LeventhallTradeoffs in marine bivalve shape and size across lattitude
  • McKenzie MandichRanked effects of heavy metals on marine bivalves in laboratory mesocosms. McKenzie successfully defended her thesis in the Spring of 2017! McKenzie is now an ESOP Fellow at ETH Zürich studying Biogeochemistry and Pollution Dynamics.


I have been a teaching assistant for the following courses at the University of Chicago:

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


  • 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 using climate proxies to reconstruct past climates
  • Participating Scientist – 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! – Developed a 30 minute interactive session for the general public on the science behind earthquakes. The show still plays at the Morehead Planetarium and Science Center today.
  • Student Coordinator – Carolina Science Café, a public venue for scientists at the University of North Carolina to discuss their research with the general public at the Morehead Planetarium and Science Center
