Jeffrey S. Guasto
Assistant Professor, Department of Mechanical Engineering


Ph.D. (Engineering), Brown University, 2009
Sc.M. (Engineering), Brown University, 2004
B.S. (Physics, Mechanical Engineering), Lehigh University, 2003


Professor Guasto earned his bachelor's degrees in physics and mechanical engineering from Lehigh University in 2003 and his Sc.M. and Ph.D. in Engineering from Brown University in 2009. He was briefly a visiting scientist at the Delft University of Technology in the Netherlands prior to joining Haverford College as a postdoctoral associate in the Dept. of Physics until 2010. He then moved to MIT as a postdoctoral researcher in the Dept. of Civil and Environmental Engineering until 2013, prior to joining the Tufts faculty later that year.

Research Interests

Professor Guasto's research program at the intersection of engineering, physics, and biology is highly interdisciplinary and motivated by complex problems in human health, the environment, and soft materials with diverse applications ranging from biomedical devices to ecosystem dynamics to micro-robotics. His primarily experimental research is centered on understanding the biomechanics of single cells, including bacteria, plankton, and sperm, and the emergent transport properties of cell suspensions and active materials through fluid, solid, and statistical mechanics approaches. To study fluid and biological physics at micron scales, Professor Guasto's research incorporates state-of-the-art experimental methods including microfluidics, optical techniques, high-speed video microscopy, and quantitative image analysis.

General research interests include:

  • Biophysics and Soft Matter: flagellar mechanics, chemotaxis, colloids & suspensions
  • Fluid Mechanics: low Reynolds number hydrodynamics, swimming microorganisms
  • Transport Phenomena: mixing in active materials, bacterial transport, dispersion
  • Microfluidic Devices: cell separation, fluid flow & chemical gradient generation
