General Interests

"The diversity of organisms that fills the world has always fascinated me. Both for large multicellular organisms like an oak tree, an elephant, or a human as well as single-celled organisms like paramecium or dinoflagellate, there are seemingly endless forms and shapes that they can take. In my lab I use the understudied unicellular organism Stentor coeruleus as a model to study how these amazing cells are able to generate, and regenerate, their complex anatomy. Even though they are just one cell, S. coeruleus can be up to 1 millimeter in length and can be seen without the aid of a microscope. Even more amazing is that when the cell is injured, or even physically cut in half, they can fully regenerate and replace any of the missing structures with incredible precision. We use a mixture of cell and molecular biology as well as genetics to investigate the genes required to build, and regenerate these amazing cells."
