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.



The latest news and developments from the Green lab at BU.

SNIPRs take aim at disease-related mutations

Researchers from the Green lab at Arizona State University have reported a highly specific method for detecting point mutations. The technique can be applied in living cells and paper-based diagnostic tests, offering a rapid, highly accurate and inexpensive means of identifying mutations relevant to human health. The work is published in Cell. (ASU Biodesign story)

Her research focuses on reengineering nonribosomal peptide synthesis and developing novel diagnostic methods. In her spare time, she likes travel, cooking, and watching TV series. 

Griffin McCutcheon

Griffin graduated in 2014 from Johns Hopkins University in Chemical and Biomolecular Engineering. Following work at the NASA Ames Research Center, Griffin joined the the Biological Design PhD program in 2017. His research is focused on RNA-based circuits and genetic encoding of novel materials and structures. Outside of the lab, Griffin enjoys cooking, home improvement, and woodworking, as well as mountain biking.

Zhaoqing Yan

Zhaoqing joined as Ph.D. student in 2017 and is in the BU MCBB program. He completed his B.Sc. degree in chemistry at the University of Jinan in 2016. He is interested in the programming DNA and RNA molecules that can be used for reporting or recording dynamic biological events. In his spare time, he enjoys playing badminton, dubbing, and playing flute.

Zachary Ticktin

Zach is a 4+1 student completing his masters in Biomedical Engineering. He is interested in designing biological circuits to detect infectious diseases and modulate gene expression. Outside of the lab he enjoys golfing and working as a medical scribe in the Banner Thunderbird Emergency department.
