Hacks & ChopsAssociate Professor of Physics and William D. and Flora McCormick Chair in Biophysics Rachel Pepper has co-authored a new paper published in the Journal of the Royal Society Interface. The paper, titled, "Active sinking particles: sessile suspension feeders significantly alter the flow and transport to sinking aggregates," explores how these sinking particles, which are hotspots for microbial life, affect aquatic ecosystems. Pepper's research lays the groundwork for understanding the role of these aggregates in large-scale processes such as carbon sequestration in the ocean or efficiency in wastewater treatment plants.
