September 2015 CU SRP Seminar by Dr. Angelia L. Seyfferth, Increasing Rice Yields and Decreasing Human Health Risk Through Soil Silicon Management

Left to right: Steve Chillrud, Ben Bostick, Angelia Seyfferth, Yan Zheng, Lex van Geen

Dr. Angelia L. Seyfferth, Assistant Professor with the Department of Plant and Soil Sciences at University of Delaware, gave the first talk for the Columbia University 2015-2016 SRP Seminar Series. Her presentation “Increasing Rice Yields and Decreasing Human Health Risk Through Soil Silicon Management” examines how to maximize the production of rice while lowering its levels of arsenic, thus reducing human health impacts from such exposures.

May 2015 CU SRP Seminar by Dr. Manish Arora, "Uncovering early life exposure to chemical mixtures using tooth matrix biomarkers"

Dr. Manish Arora and Dr. Joe Graziano, CU SRP May 2015 Seminar

This seminar/webinar focused on bio-monitoring exposure to chemical mixtures. Dr. Manish Arora, Associate Professor with the Department of Preventive Medicine and Director of the Exposure Biology Laboratory at Icahn School of Medicine at Mount Sinai presented, "Uncovering early life exposure to chemical mixtures using tooth matrix biomarkers". The seminar took place at Columbia University's Lamont Campus and was also broadcast as a webinar. There is no recording of this presentation, nor are the slides available since the findings have not yet been published. However, if you are interested in more information on this research, you may contact Dr. Arora directly via email: manish dot arora at mssm dot edu.
