Cellular Sensing and Computing Systems
We engineer RNA networks that enable living cells to detect intracellular RNA molecules and perform computations.
Welcome
Welcome to the website of the Green lab in the Biomedical Engineering Department at Boston University.
Research
Our group pursues highly interdisciplinary research at the interfaces of chemistry, biology, and materials science. Much of this work exploits programmable molecular interactions between nucleic acids and proteins to direct the assembly of nanometer-scale organic and inorganic components and to construct information-processing circuitry inside living cells. These efforts have wide-ranging implications for biotechnology, medicine, biosensing, and nanotechnology.
Low-Cost Portable Diagnostic Systems
We develop low-cost portable diagnostics that can be used to detect pathogens in low-resource settings.
Novel Antimicrobial Materials and Coatings
We develop new antimicrobial materials that are active against broad classes of drug-resistant bacteria and fungi.
Production and Chemical Modification of 2D Materials
We produce and chemically modify two-dimensional materials with novel electronic, optical, and mechanical properties.
