Peter C. Searson is the Joseph R. and Lynn C. Reynolds Professor of Materials Science and Engineering. He directs the interdivisional Institute for NanoBioTechnology (INBT) launched in May 2006, which brings together researchers from medicine, engineering, the sciences, and public health to create knowledge and develop technologies to revolutionize health care and medicine. INBT has more than 190 affiliated faculty members. Searson has secondary appointments in the Johns Hopkins University Krieger School of Arts and Sciences Department of Physics and Astronomy and the Johns Hopkins Kimmel Cancer Center. Searson also served as director of the Johns Hopkins Center for Nanotechnology Excellence from 2009 to 2015. His research interests include surface and molecular engineering and semiconductor quantum dots. His current research efforts focus on developing strategies to improve systemic delivery to a solid tumor by the enhanced permeability and retention effect, and developing in vitro models of the tumor microenvironment to visualize steps in the metastatic cascade.
