Herdeline Ardoña Receives HHMI International Research Fellowship

Congratulations to Herdeline Ardoña of the Tovar group for receiving the Howard Hughes Medical Institute's International Student Research Fellowship!  This year, the HHMI selected 45 graduate students from 18 countries for fellowships that will help them complete their graduate studies in the life sciences.  She is one of two students from the Philippines to receive the fellowship since it began in 2011.  Click here for more information.

Dr. Kit Bowen Receives Department of Defense's MURI Grant

Congratulations to Dr. Bowen for receiving the Department of Defense’s MURI grant!  The DOD’s Multidisciplinary University Research Initiative (MURI) program funds research teams that overlap in more than one traditional science and engineering discipline.  A total of 55 academic institutions are expected to participate in these 22 research efforts.  Dr. Bowen’s proposal, “Metalloid Cluster Building Blocks and Their Inclusion with Composites,” is one of six research efforts sponsored by the Office of Naval Research.  Click here for more information.

Colin Zhang Recognized by PRC for Scientific Achievements

Mr. Colin (Xinxing) Zhang has recently been recognized by the Chinese government for his outstanding scientific achievements as a graduate student in the United States.  The award ceremony took place on May 9th, 2015 at the PRC Embassy Annex in Washington, D.C.

Dr. Rebekka Klausen Receives Department of Energy Honor

Congratulations to Dr. Rebekka Klausen! Dr. Klausen is one of 44 young scientists across the country chosen to receive grants from the U.S. Department of Energy’s Office of Science under the agency’s Early Career Research Program. This annual award supports the development of individual research programs of outstanding scientists early in their careers.  Click here for more information.


Two Cover Articles From the Tovar Group

Benjamin Streifel’s paper, “An unusually small singlet-triplet gap in a quinoidal 1,6-methano[10]annulene due to Baird’s 4n pi-electron triplet stabilization” a collaboration with Juan Casado at the University of Málaga (Spain), was chosen as the subject for an inside cover in Angewandte Chemie (click here to read the paper).  To follow up very soon, Reid Messersmith’s review “Assessment of the aromaticity of borepin rings by spectroscopic, crystallographic and computational methods: a historical overview” was awarded the front cover of a forthcoming issue of the Journal of Physical Organic Chemistry  (click here to read the paper).  Artwork credits for both covers go to Molly Messersmith.

Dr. Craig Townsend and Two Others Honored For Contributions to Natural Products Chemistry

A dedicated issue of Natural Product Reports recognizes contributions spanning several decades from three scientists born within 6 months of each other, Craig Townsend (JHU), Tom Simpson (Univ. of Bristol)  and John Vederas (Univ. Alberta), to understanding fungal polyketide biosynthesis. While having no common mentor, each has both made fundamental advances to methods now in widespread use and delivered major insights into iterative catalysis exemplified by this family of multidomain enzymes.  Click here to read Dr. Townsend's article and the issue's dedication.

Dr. Nicole Gaudelli and Darcie Long publish in Nature
Dr. Nicole Gaudelli and graduate student Darcie Long report with Prof. Craig Townsend the discovery that a non-ribosomal peptide synthetase acts centrally in the formation of the beta-lactam ring of the nocardicin family of antibiotics. The mechanism of this unprecedented reaction is examined and its engineering for generalized protease inhibition is discussed.  Click here to read the article.


Mark Struble and Max Holl Featured on ACS Editors' Choice

Congratulations to Mark Struble and Max Holl of the Lectka group!  Their paper “Synthesis of a Tight Intramolecular OH---Olefin Interaction, Probed by IR, 1H NMR and Quantum Chemistry,” which was recently published in the Journal of Organic Chemistry, was selected as an ACS Editors' Choice. Click here to read the article.

Welcome New Faculty!

We are very pleased to announce two new faculty will be joining the Chemistry Department this summer 2015.  We welcome Dr. V. Sara Thoi and Dr. Thomas J. Kempa.

Dr. Sara Thoi received her Ph.D. from University of California, Berkeley with Christopher J. Chang and is currently completing her postdoctoral studies at California Institute of Technology with Sossina M. Haile.  Sara’s research interests include coordination chemistry, materials synthesis, electron and ion transport, photochemistry, and electrocatalysis.  Sara’s research will be focused on using molecular design in porous materials for the development of sustainable technologies in energy conversion and storage.

Dr. Tom Kempa received his Ph.D. from Harvard University with Charles M. Lieber and is currently completing his postdoctoral studies with Daniel G. Nocera at Harvard. Tom's research interests are in the general area of solid-state materials chemistry and experimental physical chemistry. Tom's research group will work towards building and characterizing new classes of solid-state systems that can enable advances in energy conversion, self-assembly of photonic and meta materials, and biophysical probes. The group will explore perovskite and oxide-based 2D materials and superlattices, novel strategies for kinetic assembly, and inorganic nanoprobes for interrogation of cellular networks. To accomplish this science, his group will use a rich array of gas-phase and inorganic synthetic methods and a number of solid-state optical and structural characterization techniques.

Marisa Taverna Porro Featured on ACS Editors' Choice

Congratulations to Marisa Taverna Porro of the Greenberg group. An article she coauthored, "Double-Strand Breaks from a Radical Commonly Produced by DNA-Damaging Agents.” (click here to read the article) in Chemical Research in Toxicology was chosen by the editors to be featured on the journal’s cover and the ACS Editors’ Choice website. The ACS chooses one article per day to be highlighted on its website and is published in Open Access form.

Daryl Guthrie Featured in the Journal of Organic Chemistry

Congratulations to Daryl Guthrie of the Toscano group!  An article he cowrote, “Catch and Release of HNO with Pyrazolones,” was chosen by the editors of the Journal of Organic Chemistry as a Featured Article.  Click here to read the article.
