Josette El Zaklit

Assistant Professor
Biography

Dr. El Zaklit is involved in several interdisciplinary research projects in the College of Engineering and the School of Medicine. Dr. El Zaklit's research work focuses on studying the effect of high intensity, nanosecond duration electric pulses (NEPs) on neural-type cells using a combination of numerical cell modeling and experimental approaches (fluorescence imaging). The long-term goal is to work toward the development of new, non-invasive, highly focused electrostimulation technologies for neuromodulation.
