Besides your standard top tier institutions (Stanford, MIT, etc.) I don't think another university has emerged as a synthetic bio "powerhouse". The field is still relatively young and I think only recently has been moving into these chemical biology/bioengineering programs. I wish there was a synthetic biology degree though, that would be baller.
Your stats are reasonable for these programs if you have a good SOP/letters. I would throw in Berkeley as well because of LBNL, Doudna, and other emerging PIs. There's supposed to be some sort of CRISPR oriented institute being constructed in the area that is likely to be affiliated with Berkeley. Check out biochemistry/molecular biology programs too like UCSF TETRAD (Lim, Gartner), and UCLA (Kosuri, Yeates). Also, Scripps institute in San Diego does super rad synth bio stuff like custom tRNAs and novel nucleic acids.
Hope this helps friend
