Ha’s research is focused on pushing the limits of single-molecule detection methods to study complex biological systems. His group develops state-of-the-art biophysical techniques (e.g., multicolor fluorescence, super-resolution imaging, combined force and fluorescence spectroscopy, vesicular encapsulation, single-molecule pull-down) and applies them to study diverse protein-nucleic acid and protein-protein complexes, and mechanical perturbation and response of these systems both in vitro and in vivo.

September 28, 2020Johns Hopkins researchers develop system for using everyday glucose monitors to detect COVID-19 antibodiesA trio of Johns Hopkins scientists—a pharmacologist, a biomedical engineer, and a biophysicist—are pooling their knowledge to design a device that can detect whether a person has antibodies linked to SARS-CoV-2, the virus that causes COVID-19.
December 21, 2017Andrew Feinberg ’73, MD ’76, MPH ’81, the director of the Center for Epigenetics at Johns Hopkins, recently finished his first semester teaching at the Whiting School and he says “it’s been a fantastic adventure.”
