Prof. Marilyn Erickson’s Legacy was Celebrated with a Retirement Reception

Last Thursday November 29, CFS and FST faculty and staff organized an enjoyable event to honor Dr. Erickson’s career at UGA. Dr. Erickson joined our faculty in 1987 and after 31 years of a highly productive research career, she is retiring at the end of 2018. Current and former colleagues who collaborated with Marilyn during her tenure also participated to celebrate her. More than 50 attendees came together in the Melton Building to honor Marilyn. Dr. Erickson is one of the CFS’ founding faculty who has contributed extensively to advance our understanding of pathogen ecology and survival in the fresh produce environment.

Prof. Xiangyu Deng recently co-authored a World Health Organization’s Landscape Paper entitled “Whole genome sequencing for foodborne disease surveillance.”

This document provides a good overview of the potential benefits and limitations of applying WGS in a global scale as well as it describes the barriers for its adoption in developing countries.
