On Feb 27, 2020, Rhy successfully defended his dissertation, entitled “Micro-Analytical Geochemical and Spectroscopic Investigations of the Original Context and Condition of Archaeological Biominerals and Mineraloids,” supervised by Dominique Weis. Congratulations on an excellent defence, Dr. McMillan!
PCIGR student Evelyn Freres, a PhD candidate with Dominique Weis, is featured in this week’s Meet The Scientist segment of the Geochemical Society’s news page (February 24, 2020). In this Q & A session, Evelyn provides insight into her work on the multi-collector ICP-MS and why she finds her research so fascinating.
Dominique has received the 2020 Mentorship Medal from the Canadian Federation of Earth Sciences. The award is made in recognition of her passion for helping students to achieve their potential and her transformative vision for enriching student training. Throughout her career, she has kept an exceptional track record of mentoring over 60 students and many more early career researchers. The award was created by the CFES in 2008 to recognize the sustained and inspirational mentorship of colleagues and employees including peers, graduate students, undergraduate students and technicians.
PhD Candidate Rhy
McMillan received the AGU Outstanding Student Presentation Award (OSPA) for his
poster, “Identifying long-distance transport of obsidian across the North American
landscape in antiquity based on Indigenous-led research initiatives,” presented
at AGU’s Fall meeting in December 2019.
Rhy worked in partnership with xʷməθkʷəy̓əm (Musqueam), an Indigenous community in modern-day Vancouver, BC, to investigate the geographic origins of small (<1 cm) fragments of obsidian excavated from c̓əsnaʔəm (Marpole), a key xʷməθkʷəy̓əm village site. Using a unique combination of non-destructive and minimally invasive analytical techniques, the obsidian was shown to likely originate from at least two volcanic sources as far as 1,000 km away. This evidence for long-distance trade and exchange supports the oral history and continuity of complex xʷməθkʷəy̓əm social and material networks, which still exist today.
