Bio

Brian M. Hoffman is the Charles E. and Emma H. Morrison Professor of Chemistry and Professor of Molecular Biosciences at Northwestern University, and is a member of the National Academy of Sciences. He has spent his career unraveling the mechanistic details of complex enzyme systems, exploring the details of long-range interprotein electron transfer, and studying molecular metals and the chemistry of porphyrazine macrocycles. Much of his work in bioinorganic chemistry involves the application of electron-nuclear double resonance (ENDOR) spectroscopy, a combination of NMR and EPR spectroscopies that is able to determine active site composition, as well as electronic and geometric structures, for resting states and key trapped catalytic intermediates. Among his notable achievements are major contributions to the understanding of the mechanism of nitrogenase, the active site structure and intermediates in radical SAM enzymes, and mechanisms of vital heme enzymes such as nitric oxide synthase and cytochrome P450. Prof. Hoffman is a graduate of Lane Tech High School in Chicago, and earned a bachelor of science in chemistry at the University of Chicago. His Ph.D. research was carried out at Caltech under the direction of Harden M. McConnell. He was briefly a postdoc with Alex Rich at MIT prior to starting as a faculty member at Northwestern University, where he has been ever since. He has been honored with numerous awards, including the ACS F.A. Cotton Medal for Excellence in Chemical Research, the RSC Joseph Chatt Award for Outstanding Research in Inorganic Chemistry and Biochemistry, the ACS Alfred Bader Award in Bioinorganic or Bioorganic Chemistry, and the RSC Bruker Prize for ESR. He is a member of the National Academy of Sciences and the American Academy of Arts and Sciences.

Friday, September 22

Dr. Gerrick Lindberg (Northern Arizona) will present a seminar titled "Controlling the structure of proteins with ionic liquids." Dr. Lindberg is the guest of Professor Sharon Neufeldt.

Abstract: Ionic liquids (ILs) have received significant attention in the past few decades as a novel class of materials with numerous proposed technological applications. ILs are salts that are liquid at the operating temperature; for room temperature operation this typically entails a large organic cation and a smaller anion. At the crux of their interesting behavior is the fact that they are typically polar and organic, so ILs can be designed with attributes of both aqueous and organic solvent environments. Despite all of the promise and research, there remain fundamental questions about the behavior of ILs. One particularly tantalizing area has been the use of ILs in biological systems. Recent publications from my and other groups have shown that ILs can have dramatic effects on protein structure and cell membrane permeability, but those effects are dependent on the specific system in consideration. In my group we use computational molecular dynamics simulations to predict the behavior of these systems. These techniques provide an unparalleled perspective on molecular motion at length and time scales that naturally emerge. My talk will review our recent results and future plans.

Thursday, September 28 

Dr. John Kiely will give a seminar in the Byker on how to get a job after you graduate from MSU. Although Dr. Kiely's seminar is specifically geared toward undergraduates, the information also applies directly to graduate students as they seek employment. Graduate students are welcome to attend.

The title of the seminar is "As, Bs, and Cs of graduating and going into industry: how will life and science change when you get there?"

You can preview the slides from the talk here:

There will be free pizza and time for you to talk to Dr. Kiely informally after the seminar.

Dr. Kiely is also willing to meet with students individually to discuss careers in chemistry, resumes, job interviews, etc. He will be available Friday morning, September 29, and you can talk to him after his seminar if you'd like to set up an individual meeting.

Dr. Kiely received his undergraduate degree in chemistry at Montana State University. He then earned a Ph.D. at North Dakota State University. He recently retired after a highly successful career in the chemical industry, where he worked for companies including Parke-Davis, Applied Genetics, LION Bioscience, and Gryphon Therapeutics.

Friday, September 29

Dr. Catherine Murphy (Department of Chemistry, University of Illinois at Urbana-Champaign will present "Gold Nanocrystals: Physics. Chemistry, Biology, Ecology." Dr. Murphy is the Peter C. and Gretchen Miller Markunas Professor of Chemistry, the Center for Advanced Study Professor, and the Deputy Editor for the Journal of Physical Chemistry C.  Professor Tim Minton is the host. 

Friday, October 6 - OPEN

Thursday, October 12

Graduate Student Kopriva Seminar- Ms. Amanda Byer (Broderick Lab). 3:10 pm in the Byker Auditorium

Friday, October, 13

Dr. Ed Rosenberg  from the University of Montana will present a seminar titled "Silica Polyamine Composites (SPC): new materials for metal recovery,  remediation and catalysis."  Professor Robert Szilagyi will host.

Abstract:
A novel class of solid state adsorbents has been developed at UM.  The materials have been vetted in the lab over twenty years of research and
have been manufactured and used on the industrial scale.  The first generation materials were based on amorphous silica micro particles
(150-300 microns) and more recent versions used silica nano particles and core-shell magnetite-silica nano particles.  Applications of each
type will be presented with a discussion of advantages and disadvantages of each type of SPC along with comparisons with other
commercially available ion exchange materials.

Friday, October 20 

Dr. George Stanley from Louisiana State University will present "Bimetallic Cooperativity in Catalysis: Twice the Fun!" Professor Sharon Neufeldt is the host. 

Abstract:  Homobimetallic rhodium complexes using the binucleating tetraphosphine ligand racemic-(Et2PCH2CH2)(Ph)PCH2P(Ph)(CH2CH2PEt2), et,ph-P4, are highly active and selective hydroformylation catalysts for a variety of 1-alkenes.  We have investigated the nature of the bimetallic cooperativity in this novel catalyst via extensive in situ FT-IR, NMR, kinetic, isotopic labeling experiments, and DFT computational studies, all of which indicate that the key bimetallic catalyst in acetone is a unique dicationic Rh(+2) oxidation state complex, [rac-Rh2(m-H)2(CO)2(et,ph-P4)]2+.  Unfortunately, the NMR studies clearly indicate that this catalyst system is very susceptible to deactivating fragmentation reactions. 

When a 30% water/acetone solvent system is used for hydroformylation deprotonation of the dicationic dihydride species occurs generating a less active, but far more fragmentation resistant bimetallic catalyst proposed to be [Rh2(m-H)(CO)2(et,ph-P4)]+, which out-preforms the dicationic catalyst.  Based on the fragmentation problem a new, far more strongly coordinating P4 ligand that uses 1,2-phenylene based chelating groups has been designed, synthesized, and characterized.  Studies on bimetallic complexes based on this new P4 ligand will be discussed.
