Zachary Gagnon

Ph.D. Chemical and Biomolecular Engineering, University of Notre Dame (’09)

Research Interests

  • Microfluidics
  • Electrokinetics
  • Flowtaxis, Chemotaxis, Electrotaxis

Professor Gagnon previously was a postdoctoral fellow at the Johns Hopkins School of Medicine in 2009. He earned his Ph.D. and M.S. from the University of Notre Dame in Chemical and Biomolecular Engineering (’09 and ’05m respectively). He received his B.S. from the University of Massachusetts in Chemical Engineering in 2003.

The Gagnon Lab develops new ways of utilizing electrokinetic and microfluidic phenomena for biological and biomedical applications. In particular, they are interested in how electric fields interact with fluid interfaces to induce precise injection and selective mass transport, with the goal being to apply electro-fluidic phenomena to protein purification, cell migration and rare cell isolation applications. They are also using microfluidic devices to study cell signaling. Specifically, they are interested in how living migratory cells interpret and respond to shear stress (flowtaxis), voltage gradients (electrotaxis), and chemical gradients (chemotaxis), and the interactions between these stimuli when multiple signals are applied simultaneously. They employ a range of disciplines in our lab including fluid mechanics, microfabrication, electrokinesis (e.g. dielectrophoresis, ac electro-osmosis), cell biology (cell culture, cell expression systems, cell migration assays), electrodynamics (impedance spectroscopy) and applied mechanics.
