PDF Version, Dec 2023


Dr. Josephs comes to JSNN in August 2018 after concluding his postdoctoral research at Duke University in the Department of Mechanical Engineering and Materials Science, where he was a Ruth L. Kirschstein NRSA (NIH/F32) Postdoctoral Scholar and a Duke Scholar in Molecular Medicine (Oncology and Regenerative Medicine). Dr. Josephs received his undergraduate degree from Duke University, and completed his doctorate at the University of California, Merced with his dissertation entitled ‘Single-molecule characterization and engineering of the surfaces of nucleic acid sensors’.
