Welcome to the website of the Green lab in the Biomedical Engineering Department at Boston University.

Green lab group photo May 2022


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)

Prof. Alexander A. Green

Alexander Green is an Assistant Professor in the Biomedical Engineering Department at Boston University. (More…)

Milad Babaei

Milad graduated in 2018 from BU where he obtained his Bachelors in Biochemistry and Molecular Biology and Masters in Biotechnology. His research focus entails development of DNA nanodevices that can simultaneously amplify nucleic acid targets while providing fast readout. In his spare time, he enjoys jogging and exploring designs in silico.

Jiayi Li

Jiayi grew up in China and graduated from UC San Diego with a B.S. degree in Bioengineering: Biotechnology. She joined the Ph.D. program in Biomedical Engineering at BU in 2020. She is interested in engineering RNA-based circuits for imaging and biosensing. In her free time, she enjoys listening to music and reading fantasy novels.

James Robson

James earned his bachelor’s degree in biomedical engineering from Boston University in 2020 and joined the Ph.D. program in the same year. As an SB2 trainee, he is interested in engineering biological systems by designing RNA and DNA structures to modulate gene expression. Outside of the lab, he enjoys playing in local orchestras, chamber ensembles, and wind ensembles, as well as baking, watching movies, and volunteering.

Rebecca Kang

Rebecca is from Singapore. She graduated from Carnegie Mellon University with a B.S. in Chemical and Biomedical Engineering and joined the BU BME Ph.D. program in 2019. Her research focuses on nucleic acid design for synthetic biology in cell-free systems and mammalian cells. Outside of the lab, Rebecca is part of a loving spiritual family at Symphony Church. She enjoys boxing and trying out new restaurants.

Dayna Francis

Dayna is a senior studying biochemistry and molecular biology. She is gaining experience in synthetic biology and learning about RNA circuits to further medicine. In her free time, she loves to experiment with hairstyles/hair colors, cook, and spend time with friends and family.
