Just graduated from Yale with a B.S./M.S. in Molecular Biophysics & Biochemistry (with honors). Grateful for the research, mentorship, and community that shaped me. Excited to begin my Ph.D. in Molecular Biology at Princeton this fall. #SynBio #FGLI #PhDLife #Yale #Princeton

Congratulations to Mike and the other members of the lab for this amazing paper. I know how much work went into this, and I'm proud to have such amazing colleagues!
Amazing work from Farren Isaacs team at Yale - reducing E.coli's genetic code down to only using a single stop codon. A 62 codon GRO with lots of potential for applications. www.nature.com/articles/s41...
Engineering a genomically recoded organism with one stop codon - Nature
Ochre, a strain of Escherichia coli engineered to have a single stop codon, enables reassignment of four codons for non-degenerate functions, such as incorporation of non-standard amino acids into pro...
