I wish to apply to graduate school (and potentially work in this group as a PhD student).
II’m pleased that you are interested in the important areas of research in which we are engaged and in the SEAS graduate program. I am no longer taking new graduate students into my own research group but I continue to collaborate with other faculty members and their PhD students so you should check them out:
Zachary Schiffer (SEAS), Richard Liu (Department of Chemistry & Chemical Biology in the Faculty of Arts and Sciences) and Dawei Xi (currently at UC Berkeley; joining SEAS some time in 2027).
Please see also the following SEAS web pages:

and

Good luck with the application process!
