Professor Emerita of Biological Sciences

W.T. Evert Ting, Ph.D.


My research interests are in applied food and environmental microbiology.

Research Overview

Prof. Ting is a food microbiologist by training. However she is always interested in solving environmental problems using microbial approach.

Her current projects include screening bacterial strains and protective materials for making self-healing concrete, and studying methods to control mycotoxins in oil seeds.

Microorganisms fascinate me because they are everywhere and impact us every day in many different ways. I always tell my students that knowledge in microbiology can benefit them throughout their lives. For example, they will know how to avoid infectious diseases and how to handle food properly to reduce food spoilage and foodborne illnesses.

Teaching Focus

In addition to Introductory and Basic Microbiology courses, Prof. Ting teaches advanced microbiology courses such as Food, Medical and Environmental Microbiology. She has mentored many graduate (thesis and non-thesis) and undergraduate students conducting research in her lab, and encouraged them to disseminated their research results through conference presentations and journal publications.
