The Lew lab is studying how cell shape flexibility contributes to an organism’s success in various habitats. Both the little, round (yeast) and large tube-shaped cells (hyphae) in this image are cells of the same fungus, Aureobasidium pullulans. This beautiful fungus grows all over the world: in oceans, on land plants, in salt lakes, in arctic ice, and even in house dust! It is also able to grow cells in a variety of shapes and divide in different ways.
