We explore and study biological diversity to understand nature and discover systems and processes that may be harnessed through bioengineering for the improvement of human well-being.

Recent Highlights

TIGR-Tas: A family of modular RNA-guided DNA-targeting systems

February 27, 2025

Faure, Saito, Wilkinson et al. discover a new family of RNA-guided systems, called TIGR-Tas. Tas proteins use a unique tandem guide to recognize target DNA. Read more in Science.

Rational engineering of minimally immunogenic nucleases for gene therapy

January 2, 2025

Raghavan, Friedrich, et al. design and test reduced immunogenicity (Redi) variants of SaCas9 and AsCas12. Read more in Nature Communications.

Reprogrammable RNA-targeting CRISPR systems evolved from RNA toxin-antitoxins

February 18, 2025

Zilberzwige-Tal, Altae-Tran, et al. trace the evolutionary origins of Cas13 to AbiF, a toxin with a non-coding RNA anti-toxin. Read more in Cell.
