Alexandra E. LaLonde's Homepage

Research at Rochester Institute of Technology

Alexandra is a fourth year biomedical engineering student at RIT. She is currently conducting a reasearch project in microfluidics which focuses specifically on how the viability of cells is affected by exposure to an electric field using insulator-based dielectrophoresis.

Academic Background
