Brandon  Bloomer picture
Brandon Bloomer
Brandon was born and raised in the suburbs surrounding Philadelphia, PA. He conducted his undergraduate studies at Temple University, where he worked in the lab of Scott Sieburth on the [4+4] photocycloaddition chemistry of 2-pyridones. He later worked in the lab of Sarah Wengryniuk to develop pincer Ni(II) catalysts for the oxidative C-H functionalization of arenes.

Having developed an intense interest in organometallics, and motivated to apply it in biological systems, Brandon joined the Hartwig lab in the Summer of 2017 and is currently studying the development of novel artificial metalloenzymes.

In his free time, brandon enjoys walking, running, and watching budget horror films.

Eric Kalkman
Eric Kalkman was born in 1995 and raised in the suburbs around St. Paul, Minnesota. He earned his B.S. in chemistry and computer science at the University of Minnesota, Twin Cities. While there, he worked in the lab of Prof. Ian Tonks developing heterobimetallic catalytic cycles in an effort to introduce a greater degree of programmability into ethylene polymerization and α-olefin hydroesterification. Following a brief stint in the Hartwig lab during the summer of 2016, Eric returned in the fall of 2017 to expand his understanding of organometallic transformations. He is currently studying catalytic fluoroalkylation. Outside of lab, he enjoys learning languages (both spoken and for programming), tinkering with his computer, and playing the violin.

Caleb Karmel

Caleb Karmel was born in New York, New York in 1993. He received his B.S. from Rice University in 2015. There, he worked with Dr. Zachary Ball synthesizing rhodium peptide complexes and related complexes that will help probe protein-protein interactions. In 2015, Caleb decided that biology was too complicated for him and that he would do research in organometallic chemistry. He joined the Hartwig group in Fall 2015 and is working on directed C-H silylation chemistry. Outside of the lab, Caleb enjoys bad sci-fi movies and trying every burrito in the bay area.

Taegyo Lee

Taegyo Lee was born in Incheon, South Korea in 1988. He received his B.S. in chemistry from Seoul National University, where he worked in Prof. Chulbom Lee's group on rhodium vinylidene-mediated reactions. Fascinated by the beauty of organometallic catalysis, he crossed the Pacific Ocean to come to Berkeley (of course, by plane) and joined the Hartwig group in 2013. Currently, he is working on directed C-H silylation chemistry. Outside the lab, he enjoys practicing tennis and watching his favorite TV show, the Big Bang Theory.

Zachary Litman

Zachary Litman was born in Dallas, Texas in 1988. During high school he worked in the labs of Dr. Michael Brown at UT Southwestern and Mario Capecchi at the University of Utah (molecular biology). He received his B.S. from Yale University where he worked in the lab of Scott Miller. His research focused on the development of novel small peptide catalysts for the selective halogenation of biaryls. Specifically, he investigated the purported mechanism of a reported transformation. Intrigued by the powerful transformations published by the Hartwig group, Zach came to UC Berkeley joined the group in 2012. He is currently working on C-H amination. Outside of lab Zach enjoys movies, building things, and writing about himself in the third person.
