Laura Ong
Associate Professor of Biology


I always knew that I wanted to teach, even before I knew what I wanted to teach.  And now, after several years of academic and geographical roaming, I am thrilled to be back home in the mountains, teaching at King University.  I grew up in Greene County, Tennessee as a child of a music teacher and a tobacco breeder.  Since many of my extended family farmed tobacco, my initial interest in biology stemmed from a desire to boost disease resistance in crop plants, to help improve yields and incomes in farming communities.  However, once I started to learn the intricate details of the interactions between pathogens and their hosts, I began to appreciate all types of disease-causing microbes for their own sakes.  I love to learn about, and teach about, anything related to microbes and/or disease.

During my graduate work, I studied plant defense mechanisms at the cellular and molecular level.  My dissertation research focused on protein-level interactions between the bacterium Pseudomonas syringae and two of its plant hosts, soybean and the model plant Arabidopsis.  My research results indicated that a particular P. syringae virulence protein altered target proteins in soybean and Arabidopsis plants in similar ways, suggesting that both plants use related mechanisms to combat a single bacterial disease.  This research gives me hope that plant disease resistance research in Arabidopsis will translate fairly quickly and easily to the improvement of crop plants.

So far, the courses I have taught at King University are Principles of Biology, Microbiology and Immunology (for non-Biology majors), Microbiology (for Biology majors), Human Anatomy and Physiology 2, Cell Biology, Plant Biology, Interdepartmental Science Seminar, and an honors seminar in Modern Human Reproduction.  While I originally specialized in plants and microbiology, I really enjoy teaching human anatomy and physiology as well, because everyone has a body, and everyone should know how their body works!

I am a mom to three handsome, noisy, messy, and absolutely perfect sons, and much of my time away from King is spent taking care of them.  In my remaining spare time, I love to sing, garden and read fiction, and my all-time favorite author is Alexander McCall Smith.  If I myself were a fictional character, I would probably be Hermione Granger or a hobbit.  I also love watching collegiate wrestling and traveling with my husband.
