MTS3 Ute Hentschel - Symbiotic Sea Sponges

Ute Hentschel is a professor of chemical ecology at the University of Würzburg in Germany. Her research focuses on characterizing the microbial communities associated with marine sponges, the diversity of these symbionts and their activities. On this episode, I talk with Ute Hentschel about her research on the microbes that live on and in sea sponges – those squishy, colorful residents of coral reefs. Dr. Hentschel describes some of the utterly unique microbes that are only found in sponges, what those microbes get from living in a sponge hotel, and why it’s nice to have a study site in the Bahamas.

MTS2 - Seth Darst - RNA polymerase

Seth Darst is a professor of Molecular Biophysics at the Rockefeller University in New York city, where his research centers on RNA polymerase, the enzyme at the heart of a cell’s ability to make protein from a set of DNA instructions. In this interview, I talk with Dr. Darst about how he got his start in research, whether computers will eventually be able to predict complex protein structures, and why eager young scientists shouldn’t miss their chance at postdoctoral training.

MTS1 Ralph Tanner - The Future of Biofuels

Ralph Tanner, a professor of microbiology at the University of Oklahoma, focuses his research on anaerobes in the environment and putting those bacteria to use in industry. He develops useful microbial catalysts for biofuel production from sustainable crops and has extended our knowledge of microbial diversity by isolating a number of new genera and species with novel physiologies. He helped define the phylogeny of bacteria. In this podcast, I talk with Dr. Tanner about his work producing biofuels from burnt plant material, the future of biofuels in the U.S., whether bacterial systematics might be forced to change in light of new research on recombination, and about his approach to teaching microbiology.
