Who I am...
I am an evolutionary biologist with an active interest in biochemistry.
My interest in evolution was sparked in 1978 by Willard A. Taber, my undergraduate microbiology teacher at Texas A&M, who during one lecture said "Some people think that chloroplasts arose from free-living cyanobacteria." I wanted to know more. When I finally got around to my first encounter with laboratory research, I jumped at the chance to work with Rüdiger Cerff at the University of Hannover (Germany) on cDNA cloning and sequencing of chloroplast-cytosol isoenzymes for glyceraldehyde-3-phosphate dehydrogenase, GAPDH. The sequences for these isoenzymes offered a test of one of the crucial predictions of endosymbiotic theory, namely that the sequences of nuclear genes for enzymes essential to chloroplast physiology should be more similar to prokaryotic homologues than to the nuclear genes for their cytosolic homologues, which should represent the history of the host that acquired the plastid. If so, that would be evidence for gene transfer to the nucleus in the wake of endosymbiotic origin of plastids (Martin and Cerff, 1986), or endosymbiotic gene transfer, as we later called it (Martin et al., 1993).
My introduction to evolution thus struck roots in a world where most of the genes that plastids have brought into the eukaryotic lineage were expected to be located in the nucleus. My science thus started out in a field where both endosymbiosis and gene transfer in evolution were essential parts of the equation, for how else could one explain why chloroplasts and mitochondria were so similar to modern prokaryotes while harboring only enough organelle DNA to encode for a handful of proteins at best. With an interest in endosymbiosis, and an experimental handle on the topic — molecular evolution — I became very interested in the origin of mitochondria and the nature of the host that acquired the mitochondrion. The host was somehow related to archaea. This led to questions like what kind of archaeon that host might have been, exactly, or what the nature of its physiological interaction with the ancestral mitochondrion at the onset of that symbiosis was. I wanted to know more, but the literature only offered so much in the way of ideas to test.
When one starts probing phases of evolution that go that far back in geological time, issues surrounding the origin of the very first cells is not far off, and since eukaryotes descend from prokaryotes via symbiosis, the origin of life boils down to the origin of prokaryotes, of which there are two very different kinds: bacteria and archaea. One day in 1998, Mike Russell, a geochemist, sent me one of his papers on origin of life and it wasn't too long before we got together and started writing papers together. Mike and I delivered our first paper at a wonderful Royal Society Discussion meeting organized by John F. Allen. At that meeting, I had my first encounter with Nick Lane — we ended up having a lot of interests in common, and have had a great time writing papers together since.
How I got here...
I completed my undergraduate degree in Biology at the University of Hannover, completed my PhD in Genetics under the wise and generous supervision of Heinz Saedler at the Max Plank Institute for Breeding Research in Cologne. After my PhD, I returned to Rüdiger Cerff's group, which had moved to the University of Braunschweig, where I worked for 10 happy and productive years. In 1999 I was lucky enough to receive offers for professorships from several German universities, Annette (my wife) decided that I should accept the offer from Düsseldorf, where we have been since.
I have served as an Editor for many journals over the years and I am currently the Editor in Chief of Genome Biology and Evolution.
What I do...
My group here in the Institute for Molecular Evolution pursues research on the biochemistry and evolution of chloroplasts, mitochondria (including their anaerobic forms, hydrogenosomes), and eukaryotes. We use laboratory experiments and bioinformatic techniques to pursue these questions and to probe even earlier phases of evolution, going back to life's origin, with the help of gene and genome comparisons.
