Tremendous advancement of basic biological knowledge has come from genetically manipulating model organisms to test mechanistic hypotheses. But the selection of traditional model organisms available offers a limited view of biological diversity, meaning that they cannot be used to investigate a broad swath of novel and important processes. Now an international team of scientists including Jackie Collier, Ph.D., an Associate Professor in the School of Marine and Atmospheric Sciences (SoMAS) at Stony Brook University, is investigating how to genetically manipulate a variety of marine protists –unicellular microscopic organisms that are not classified as a plant, animal or fungus – to develop new experimental models that may help to advance scientific understanding in oceanography and other areas of the biological sciences.
