Postdoctoral Associate, 2012, University of Pittsburgh, Pennsylvania
Ph.D. Chemistry, 2010, Vanderbilt University, Tennessee
M.S. Chemistry, 2003, Chungnam National University, South Korea
Ki Bum Hong hails from Daejeon, Korea where he completed B.S. and M.S. degrees in Chemistry at Chungnam National University, Daejeon, South Korea. He joined the Johnston group in 2004 and has recently extended the scope of the Bronsted acid-catalyzed anti-aminohydroxylation reaction while clarifying details related to its mechanism. Of particular note is his discovery and documentation (with Matt Donahue) of secondary catalysis by water in triazoline decomposition reactions under acidic conditions. Ki Bum was a postdoctoral associate with Peter Wipf at the University of Pittsburgh from 2010 to 2012, and returned to the group in 2012 as he applies for an academic position in South Korea.

Michael Danneman
Michael Danneman
B.S. Chemistry, 2010, Xavier University, OH
Michael Danneman is a native of Kentucky and completed his undergraduate studies in chemistry at Xavier University in Cincinnati, Ohio. With the mentorship of Professor Rick Mullins, Michael worked toward the total synthesis of pilosinine. He matriculated at Vanderbilt in 2010, and joined the group after his rotations. Secretly, we are hoping he will share knowledge of a certain recipe from his former employer Skyline Chili. 
Brandon Vara
Brandon Vara
B.S. Chemistry, 2010, James Madison University, VA

Although born in Irvine, California, Brandon represents the traffic-laden suburbs of Northern Virginia and received his B.S. in Chemistry from James Madison University in Harrisonburg, Virginia. At JMU Brandon worked with Professor Kevin Minbiole exploring cyclopropane fragmentations and subsequent rearrangements to azepines and piperidines. In the summer of 2009, he interned with Amgen in medicinal chemistry as a wide-eyed undergraduate and developed diterpene libraries via unique biooxidations. Beginning his graduate studies in chemistry at Vanderbilt in 2010, Brandon is currently working towards novel Nutlin-3 derivatives using chiral proton catalysis. He enjoys baseball, interest rates, and wide variety of coffee beverages.

Ken Schwieter
Ken Schwieter
B.S. Chemistry, 2011, Xavier University, OH

Chapter 1. Ken was born and raised in Cincinnati, OH. He began at Xavier University in 2007 and worked with Prof. Rick Mullins as an undergraduate researcher. Provided a furlough for the summer, he joined the privileged (albeit dubious) ranks of NSF-REU students at Vanderbilt, and more specifically, the Johnston group. Ken assisted the PBAM scale-up campaign, and prepared a novel BAM ligand. Ken is an avid collector and amateur model for St. X, Xavier, and Vanderbilt T-shirts.

Chapter 2. Ken matriculated at Vanderbilt in 2011, and completed his rotations during the Fall. He then joined the group in January 2012 and is developing the enantioselective synthesis of aliphatic a-amino acids using a combination of chiral proton catalysis and Umpolung Amide Synthesis.

Daniel Sprague
Daniel Sprague
B.S. Biochemistry, 2011, University of Miami, FL
B.S. Chemistry, 2011, University of Miami, FL
Dan grew up in New Jersey, but flew south for college to the University of Miami. He completed his B.S. Biochemistry and B.S. Chemistry degrees (General Honors) in 2011 with magna cum laude distinction. While at Miami, Prof. Norito Takenaka inspired him to begin research in organic chemistry, through which Dan prepared several new helically chiral catalysts for enantioselective catalysis. Dan completed his rotations at Vanderbilt during the summer and Fall, and joined the group in January 2012. He is investigating chiral proton catalyzed enantioselective hetero-Diels-Alder reactions.
