Our research is focused on understanding secondary (dorsal-ventral) axis specification and patterning in the sea urchin. We are interested in producing a systems-level description for this series of events that occur during the first 48 hours of development following fertilization. Sea urchin, a non-chordate deuterostome, is an ideal model organism for systems-level developmental studies. Genomic analysis has revealed that sea urchins share the diversity of signaling and transcriptional molecules with vertebrates, including humans, but lack the complexity associated with a duplicated genome. Further, sea urchin larvae are morphologically quite simple, being composed of approximately 15 cell types, and thus are accessible to detailed analysis of cell specification and cell-cell communication mechanisms. Finally, the use of gene regulatory networks to model developmental processes was pioneered in urchin, providing a strong precedent for this work. The lab is focused primarily on two projects: understanding how the peripheral nervous system is specified, and how the larval skeleton is patterned.

Current research suggests a certain type of tiny fungus may play a very large role in the global cycling of carbon. Professor Finzi, who took part in the research, asserts that the work is not only relevant to climate models and predictions of future atmospheric greenhouse gas levels, but also challenges the core foundation in modern biogeochemistry that climate exerts major control over soil carbon pools.Read more.
