We’re Leading the Genetic Medicine Revolution
Strand is a clinical-stage, Boston-based biotechnology company leading the genetic medicine revolution. We have taken complex mRNA medicines from design to production to patients.

We were founded by biological engineers at MIT who created the first mRNA programming language.
Our innovative approach to mRNA design and manufacturing has produced a pipeline of next gen therapeutics for cancers and autoimmune disease.
This is just the beginning. Our interdisciplinary team is working to develop new delivery systems for tissues across the body, so millions of patients can benefit from genetic medicines.

Tasuku Kitada
President, Head of R&D, Co-founder
Tasuku Kitada is President and Head of R&D of Strand Therapeutics. He co-founded Strand and serves on its Board of Directors. Prior to Strand, Tasuku was Senior Biotechnology Analyst at Candriam Investors Group, where he conducted due diligence for the company’s multi-billion-dollar biopharma public equity investment strategy. At Candriam, he focused on cell and gene therapy companies, and also covered numerous oncology companies. Currently, Tasuku continues to serve Candriam Investors Group as an advisor. Prior to Candriam, Tasuku was a researcher at the Synthetic Biology Center at Massachusetts Institute of Technology where he became the first scientist to create synthetic gene circuits using synthetic mRNA.
This was the first demonstration of post-transcriptional circuits that can be “wired” to create a variety of networks of increasing complexity, which enabled cell type specific expression as well as small-molecule based control of gene expression from synthetic mRNA. This important research led to publications in Science, Nature Biotechnology, and Nature Chemical Biology. The mRNA synthetic biology platform developed from this research has been exclusively licensed to Strand. Tasuku holds a Ph.D. in Molecular Biology from University of California, Los Angeles and a B.S. in Biophysics and Biochemistry from University of Tokyo.
