Official faculty profile: cheme.mit.edu/profile/robert-s-langer/ . Header identifies Robert S. Langer; Research Interests lists drug delivery, biomaterials, tissue engineering and biomedical engineering. The follow-up vascular paper labs.utsouthwestern.edu/sites/default/files/2022-11/23_Niklason_JVS.pdf , printed p. 628, connects the full Robert Langer byline to the same artery-engineering collaboration. Jinming Gao’s institutional CV lists that collaboration with Langer RS.
