Mei Yan Lai PhD| DERTS Trainees




Degree program: PhD, University of Alberta
Supervisor: Thomas Stachel


Mei defended her PhD on September 13, 2022. Mei went on to work with the Gemmological Institute of America (GIA) in Carlsbad, CA.

After completing her MSc on the origin of yellow colouration in diamonds from the Chidliak and Ekati (Misery pipe) kimberlites, Mei completed a PhD on diamonds from Sierra Leone (West Africa).

For her PhD Mei completed the first systematic study on diamonds and their inclusions from Sierra Leone. Previously, only a few random analysis of inclusions (e.g., two orthopyroxenes and one eclogitic garnet were analysed by Meyer and Boyd 1972) were available in the literature. Mei characterized the mineral inclusions and their host diamonds.
