Imogene Lim of Malaspina University-College in Nanaimo, British Columbia,
has done extensive archaeological and historical research on the Chinese
Canadian community on Vancouver Island. She has also led excavations in
Vancouver's Chinatown. The link to her research interests is:

She has a very good site on the historical archaeology of the Chinese
community in Nanaimo:
http://chinatown.mala.bc.ca/
The site reflects research undertaken by Dr. Lim and her students, including
Colleen Stuart.
This is not strictly "Chinese American," but seems like it would fit with
your interest in the Chinese diaspora.
