Project Grant 2444494
- This National Science Foundation (NSF) Project Grant award under the Engineering program (CFDA 47.041) aims to improve the understanding of biogenic turbulence, which refers to the mixing of heat and CO2 in the ocean driven by the motion of small organisms like zooplankton. The $259,994 award, effective from July 1, 2024 to June 30, 2027, will fund a collaborative research project between the University of Pittsburgh and other institutions to investigate the minimum swimmer size required to...
- This $361,476 National Science Foundation project grant supports research at the University of Pittsburgh to advance understanding of the two-way coupling between active matter and transport barriers in unsteady flows. Funded under the Engineering program (CFDA 47.041), the three-year award will investigate how light-guided brine shrimp interact with and influence large-scale transport structures in electromagnetically driven laboratory flows. Through two aims, the grantee will determine...
- This $340,000 Project Grant award from the National Science Foundation (NSF) Engineering program (CFDA 47.041) supports a collaborative research project at the University of California, Santa Barbara (UCSB) to investigate the minimum size of zooplankton swimmers required to generate sustained biogenic turbulence in the ocean. The research aims to improve understanding of how the motion of small organisms contributes to vertical mixing of heat and CO2 in the ocean, which is crucial for predicting...
- This Project Grant award of $569,364 from the National Science Foundation's (NSF) Engineering program (CFDA 47.041) will fund a 5-year research project conducted by Lehigh University. The goal is to develop a comprehensive understanding of the emergent behavior of finite microswimmer clusters in Newtonian and complex fluids, such as those found in biomedical applications like minimally invasive surgery and targeted drug delivery. The project will use a novel framework combining experimental,...
- This $265,007 Project Grant award from the National Science Foundation (NSF) Engineering program (CFDA 47.041) will support collaborative research to advance the understanding of bacterial swimming motion. The research aims to leverage robophysical modeling techniques from robotics to realistically emulate and study the complex interplay of physical and biological factors governing bacterial motility behaviors. Key objectives include elucidating how fluid mechanical forces shape the ways...
- This National Science Foundation (NSF) Geosciences Program (CFDA 47.050) Project Grant award in the amount of $353,715 will fund a collaborative research project to study the turbulence in the stratified layer at the air-water interface, as driven by waves and wind. The project will utilize a combination of controlled laboratory experiments and advanced numerical simulations (large-eddy simulations) to test the hypothesis that coupling between waves and wind-driven currents is necessary to...
- The National Science Foundation (NSF) awarded a $242,260 Project Grant under the Engineering program (CFDA 47.041) to The Trustees of Princeton University on April 1, 2025. The goal of this award is to (1) observe plastic particles in realistic ocean flows recreated in a controlled laboratory setting, and (2) use the observations to build a modeling framework that describes the vertical mixing and transport of plastic at the ocean surface. By examining fundamental interactions between...
- This National Science Foundation (NSF) Project Grant award under CFDA 47.050 - Geosciences program provides $181,787 to the Massachusetts Institute of Technology (MIT) to study the role of wind and waves in mixing the upper ocean. The 3-year project, effective July 1, 2024, will carry out simulations with laboratory experiments and computer models to test the hypothesis that coupling currents and waves is necessary to reliably represent the deepening of the ocean surface layer. The research aims...
- This Project Grant award of $560,532, awarded by the National Science Foundation's (NSF) Engineering program (CFDA 47.041), supports fundamental research into the fluid dynamics underlying the multi-modal autonomous operation of the aquatic whirligig beetle. The primary research objectives are to experimentally investigate the beetle's propulsion on the water surface and underwater, its diving behavior, and its use of surface ripples to detect food particles. The findings could lead to the...
- This $170,164 Project Grant award from the National Science Foundation's (NSF) Mathematical and Physical Sciences program (CFDA 47.049) supports collaborative research on the fluid dynamics of organisms filtering particles at the mesoscale. The primary awardee, the University of Tennessee, will develop open-source numerical software to elucidate the fluid dynamics of biological and bioinspired filtering arrays, including how the behavior of active particles affects filtering outcomes. The...
This Project Grant award from the National Science Foundation's (NSF) Engineering program (CFDA 47.041) provides $325,089 to the University of Pittsburgh to investigate how swarms of small marine organisms can generate large-scale water movements that contribute to ocean mixing. The 3-year project, running from August 2025 to July 2028, will use controlled laboratory experiments to study the mechanisms behind these collective active migrations and their impact on vertical mixing in the ocean. The research aims to improve predictions of ocean behavior and enhance understanding of marine dynamics, with potential applications in engineering fields such as optimizing airflow around drone swarms and improving air-water mixing in wastewater treatment. The project also includes training for students and engaging the public through educational videos and workshops.
