Currently, Derrick Butler is a National Research Council/NIST Postdoctoral Fellow in the Biophysical and Biomedical Measurement Group. He received a B.S. in Physics from the University of Vermont, USA in 2016 followed by a M.S.E. in Materials Science and Engineering from the University of Pennsylvania, USA in 2017. In 2022, he received a Ph.D. in Electrical Engineering from Penn State University, USA where his research focused on the development of electrochemical and electronic biosensors based on two-dimensional materials to detect neurochemicals and bacteria. At NIST, Derrick is developing electronic sensors on porous membranes to incorporate in an organ-on-a-chip system for the study of cardiac physiology and pathophysiology. More broadly, his research interests reside at the intersection of device physics and fabrication, materials engineering, electronics, and biology.
