I am Dr. Kenneth Dumack, a biologist working in the field of protistology. Some years ago, I started to explore the astonishing world of protists. Since then I absolved several modules associated with different research fields all around protistology, such as their ecology, diversity, phylogeny and biotechnology (of microalgae). My main interest is in species descriptions, phylogeny and autecology of non-bacterivorous protists. I focus on amoebae and amoeboflagellates in soils and their freshwater relatives. This website is meant to give an overview about my publications, interests and qualifications.
