Personal profile

Our lab studies the influence of climate on the composition, structure, and long-term evolution of lowland Neotropical plant communities. We use the fossil pollen record to document plant response to past climate variability. Because pollen and spores are widespread in the terrestrial sediment record, we are able to use these microscopic fossils to study long-term trends in plant ecology and evolution.

We seek to re-imagine the field of paleoecology and expand the range of ecological and evolutionary hypotheses that can be addressed by increasing the throughput, reproducibility, and taxonomic resolution of an unrecognized source of “big data”– the microfossil record. The focus of our current work is on developing microscopy and computer automation methods to improve the quantity and quality of pollen and spore counts. We are exploring different microscopy techniques, image analysis, and machine learning. With these new tools, we aim to develop larger and more comprehensive data sets that will expand the scope of paleoecological research. Our long-term goal is to transform the paleoecological analysis workflow, from imaging to classification to interpretation.
