What has been your favorite specimen so far? Aside from the study that we did with the electron microscope, my other interests are tracing human diseases in amber.
I worked in Africa on tropical diseases there, and so I used that experience to look at insect vectors, like mosquitoes in amber, and I knew what the stages of these parasites looked like in the vectors. So I think my most interesting [discovery] was to find evidence of malaria in mosquitoes and biting midges.
It went back million years, so now we know that malaria was around for a long time—it could very well have plagued the dinosaurs. There are many different lineages of malaria. And then the other [memorable discovery] was finding some Lyme disease spirochetes in a tick, which was very interesting, and plague-like bacteria in a Dominican tick, showing that plague-like organisms have been around for a long time as well. What are your thoughts about de-extinction—that is, using ancient DNA to resurrect organisms?
But I think it might be possible to get small snippets of DNA still, from amber specimens, in order to make comparisons with present-day forms. I think one of the problems is how to get a system to repair the DNA [extracted from amber]; we know the DNA is probably damaged at various points.
And then to find the right specimen, because once you get the amber out of the ground and it sits around for a while, air can slowly get into it. What would you resurrect, if you could? These would probably be small things that were in amber, maybe nematodes or small flies, or a cockroach, something like that. It would be nice to bring back some bacteria that actually could be cultured. That would probably be the easiest because you could culture it, and then you can make comparisons with present-day bacteria using DNA analysis.
Who are your scientific idols? Certainly Charles Darwin. I always liked reading about Charles Darwin because of his determination to stand up against public opinion back then. And also he was such an acute observer of nature and natural histories. I very much liked the books of Robert Desowitz.
He was a tropical parasitologist, and he wrote a number of popular books explaining to the public about diseases—the evolution, and things like that. His books were very interesting and well written, and I always had high regard for him. As far as growing up, when I was younger, probably I was most impressed with the writings of Bertrand Russell.
I was very interested in his theories, his humanitarian ideals, his freedom of thought, especially his book A History of Western Philosophy.
