The T-BIC consists of Rob Scarrow's research group from Haverford, Sharon Burgmayer's group from Bryn Mawr, and Liliya Yatsunyk's group from Swarthmore. Our group was initiated through Mellon Seed grants in 2009. We meet about 5 times a year on each of the three campuses for joint group meetings where students share their research findings and engage in scientific discussions in a collaborative environment. Once a year we invite an outside speaker, well-respected in the bioinorganic field, for a formal presentation. This presentation is usually accompanied by a small poster session that facilitates communication and idea exchange.
For example, during the 2009-2010 academic year Dr. Veronika Szalai from NIST (back then from University of Maryland, Baltimore County) was the first T-BIC sponsored speaker. At Haverford she gave a research seminar on interactions of copper and the amyloid-beta peptide related to Alzheimer's disease. In 2010-2011 academic year Dr. Charles Riordan of the University of Delaware gave a TBIC presentation at Bryn Mawr. His seminar focused on functional models of oxygenase enzymes using coordination complexes of nickel. In February 2014 Dr. Nicolai Lehnert from the Chemistry Department of the University of Michigan presented at TBIC the talk titled: "The first Functional Model System for Flavo-diiron Nitric Oxide Reductases".
We also hosted local research groups at TBIC, specifically those of Dr. Mark Schofield and Dr. Louise Charkoudian from Haverford, Dr. Yan Kung from Bryn Mawr. The faculty and students from these group presented their work at TBIC enriching experience of our students. TBIC meetings led to collaborative work between our three campuses.
