Brief Bios of Minisymposium Speakers

BabbittPatsy Babbitt, Ph.D is Professor and Vice Chair of Bioengineering & Biotherapeutic Science with the Department of Pharmaceutical Chemistry at the California Institute for Quantitative Biosciences at the University of California, San Francisco.  Dr. Babbitt received her bachelor's degree in Biology from Mills College in 1979 and her Ph.D. in Pharmaceutical Chemistry from UCSF in 1988.  She continued her career as a postdoctoral researcher and assistant research chemist and then joined UCSF in 1993.  Her laboratory works with using superfamily analysis to understand how protein sequence and structure determine protein function. Their computational approach begins with identifying the sets of divergently related proteins that comprise enzyme superfamilies and then attempts to correlate their conserved and variable structural features to similarities and differences in their functions. Her laboratory uses both computational and experimental methods to improve their understanding of how protein structures mediate protein function. Here, they develop and use the tools of bioinformatics and computational structural biology to integrate the information coming out of the genome projects with available tertiary structural information. One primary goal of their computational work is to develop a methodology for "rational protein design" that can be used in the laboratory to engineer new functionalities into proteins.

BaligaNitin S. Baliga, PhD is an Associate Professor with the Institute of Systems Biology in Seattle, WA. He received his B. Sc. degree in Microbiology from the University of Bombay, his M. Sc. in Marine Biotechnology from Goa University and his Ph.D. in Microbiology from the University of Massachusetts in 2000. He began his career as a postdoctoral fellow at the Institute for Systems Biology in 2000 where he remains today.  Nitin coordinates a multidisciplinary group of scientists for the purpose of constructing systems scale predictive models of biological responses to stress. Using high throughput technologies in conjunction with molecular biology, genetics, software engineering and statistical analysis his laboratory has put together an approach for deconstructing biological circuits in any microbe (and some eukaryotes) into predictive models. He is now integrating microfluidics and high resolution modeling into their approach to make these models suitable for re-engineering. Nitin will present some recent findings from applications of this approach to the study of OSR. He has received numerous grants, serves as an Editorial Board Member of BMC Systems Biology and has over 35 publications.

BaryckiJoseph J. Barycki, PhD graduated from the University of Rochester with a Bachelor's degree in Biology in 1991 and from the University of Delaware with a Ph.D. in Biochemistry in 1997. He worked as a postdoctoral associate at the University of Minnesota in Leonard Banaszak's laboratory in protein crystallography. Dr. Barycki began his career at the University of Nebraska - Lincoln in 2002 and is currently an Associate Professor in the Department of Biochemistry and mentoring council member of the Redox Biology Center. His research program is focused on the two major thiol-based redox buffers of the cell, thioredoxin and glutathione. These two biomolecules are largely responsible for the tightly controlled maintenance of intracellular reduction-oxidation status essential for normal cellular function. His lab uses protein crystallography in combination with site-directed mutagenesis, enzymology, protein chemistry, and other biophysical techniques, to examine the biological functions of the enzymes responsible for maintaining reduced glutathione and thioredoxin reservoirs.In addition to redox homeostasis, his group is also involved in several collaborative projects focused on structure and function relationships in enzymes of biomedical significance. Most recently, they have been collaborating with the Simpson lab on enzymes involved in hyaluronan metabolism.

ChangChristopher J. Chang, PhD is an Associate Professor with the Department of Chemistry at the University of California at Berkeley and an Investigator with the Howard Hughes Medical Institute. He received his B.S. and M.S. degrees from Caltech in 1997. After spending a year as a Fulbright scholar in Strasbourg, France, Chris was an NSF and Merck predoctoral fellow at MIT and received his Ph.D. in 2002 under the supervision of Prof. Dan Nocera, where his thesis focused on the application of proton-coupled electron transfer as a mechanistic platform for developing catalytic oxygen reduction and evolution reactions. He stayed at MIT as a Jane Coffins Childs postdoctoral fellow with Prof. Steve Lippard from 2002 to 2004, working on zinc sensing for neuroscience applications and then began his independent career at UC Berkeley in July 2004. He is currently an Associate Professor of Chemistry at UC Berkeley and Investigator of the Howard Hughes Medical Institute. Chris' research laboratory currently uses a combination of inorganic chemistry, organic chemistry, chemical biology, and molecular biology approaches to study problems in neuroscience, immunology, energy research, and green chemistry. His honors and awards include a Camille and Henry Dreyfus New Faculty Award (2004), American Federation for Aging Resesarch Award (2005), Arnold and Mabel Beckman Young Investigator (2005), National Science Foundation CAREER Award (2006), Packard Fellowship for Science and Engineering (2006), Alfred P.

FomenkoDmitri Fomenko, PhD is Assistant Professor in Department of Biochemistry - University of Nebraska. He received his M.S. degree in Biotechnology from the Academy of Fine Chemical Technology (Moscow, Russia) in 1995 and his Ph.D. degree in Molecular Biology from the Institute of Molecular Genetics (Moscow, Russia) in 1999. Dmitri's laboratory studies the roles of thiol oxidoreductases in thiol-dependent redox processes and thiol-mediated signaling in cells. He combines the use of high throughput computational methods with experimental approaches in research work by developing and employing various bioinformatics methods that take advantage of genome sequencing, proteomics and functional genomics projects, and which are followed with in vitro and in vivo tests of the in silico predictions. Dmitri's research focuses on the roles of thiol peroxidases in hydrogen peroxide mediated signaling, on the thiol-based redox system in the endoplasmic reticulum, redox control of protein folding and protein glycosylation and roles thiol-dependant processes in different physiological and pathophysiological conditions. One of Dmitri's research directions is related to in silico identification and experimental characterization of selenoproteins - the narrow group of oxidoreductases with selenocysteine in place of redox-active cysteine.

JakobUrsula Jakob PhD is an Associate Professor with the Department of Molecular and Developmental Biology at the University of Michigan. Dr. Jakob received her B.S. degree in 1991 from Regensburg University in Germany, and her Ph.D. in 1995 also from Regensburg University. From 1996 until 1998 she was a postdoctoral Research Fellow at the University of Michigan with a fellowship from the German government, and from 1998 until 2001 she was an Assistant Research scientist at UM. She has been chosen as a "Biological Scholar" at the University of Michigan, a prestigious designation awarded by a University-wide committee. She is also a recipient of the Burroughs Wellcome Fund Career Award in the Biomedical Sciences 2000. In addition, she won a Sokol Postdoctoral Award in 1998. Her research is focused on the biochemical aspects of the bacterial response to heat shock. They are very interested in discovering new redox regulated proteins. Therefore, her lab has developed Redox Proteomics techniques, which allow them to determine the exact thiol-disulfide state of hundreds of cellular proteins in a single experiment. Redox-Proteomics allows us to see the global changes in the thiol-disulfide status of proteins that happen in the cell when it is exposed to oxidative stress conditions. In this way we can learn about the oxidative stress that occurs in aging organisms and how cells can better cope with it. When we combine redox proteomics with genetic experiments, we can also use it to find substrate proteins of oxidoreductases

SaltDavid E. Salt, PhD is a Professor in the Department of Horticulture at Purdue University. His long term research interest is to understand the function of the genes and gene networks that regulate the plant ionome (elemental composition), along with the evolutionary forces that shape this regulation. To achieve this his laboratory couples high-throughput elemental profiling, with bioinformatics, genomics and genetics, biochemistry and physiology in both genetic model species (yeast, Arabidopsis thaliana and rice) and "wild" plants that hyperaccumulate various metals (Cd, Ni & Zn), metalloids (As) and non-metals (Se) in their native habitat including various Thlaspi, Pteris and Astragalus species. David E Salt has been involved in such work since his Ph.D (Liverpool University, UK, 1985 - 1988) working on the mechanisms of copper tolerance in Mimulus gutattus (yellow monkey flower). He also has a B.Sc in Biochemistry (University of North Wales, Bangor, UK, 1981 - 1984) and an M.Sc in Computer Science (Hallam University, UK, 1984 - 1985), and has held faculty positions at Rutgers University (1993 - 1997), Northern Arizona University (1998 - 2001), and is currently a Professor at Purdue University, where he has been since 2001. David E Salt has published over 80 peer reviewed papers since 1989 with currently approximately 4000 citations.
