Pre-Med: Microbiology, Nutrition, and Human Disease

Dr. Jonna Coombs is a Microbial Ecologist, which is a fancy way of saying that she studies microscopic organisms and their relationship with the world around them.

This includes the interaction of microbes with other organisms like human beings. Her research focus is bioremediation, which is the use of living organisms to “clean up” pollutants in the environment. Specifically, she looks at heavy metals such as zinc, cadmium and lead. Because heavy metals are elements on the periodic table, they cannot be broken down, but instead can be changed into less-toxic forms or locked into molecules that are not soluble in water. This can help to decontaminate polluted environments. Dr. Coombs had a B.S. in Biology from the University of Maine, and a Ph.D. from Penn State University. She joined the faculty at Adelphi University in 2005.
