Can you describe some highlights from your current research for me?

We study the evolution of eukaryotic cells. There are two kinds of cells on the planet: prokaryotes, such as morphologically simple bacteria and archaea, and then the relatively more complex eukaryotes - for example plant and animal cells, amoeba, paramecium, and so on. Eukaryotes have enclosed nuclei and compartmentalized organelles, which prokaryotes lack.  Usually when you see such a big jump in complexity you expect to find intermediate forms, for example in the fossil record or in living organisms.  The mystery is that there are no intermediate eukaryotes.
