McMaster’s Henry Schwarcz has been made a Fellow of the American Association for the Advancement of Science.

The world’s largest scientific society elevated the professor emeritus to Fellow for his pioneering development and application of stable isotope analysis for environmental Earth sciences, geoarchaeology and the reconstruction of human history.

Schwarcz studies isotopes to better understand everything from temperature to diet during ancient times.

His most recent research involved reconstructing the climate of the Middle East during the rise of agriculture by analyzing isotopes of oxygen found in the teeth of goats.

New Fellows will be celebrated at the AAAS Fellows Forum in Chicago on February 15.

Below, Schwarcz explains his research in a video posted to this website.
