Chung-Jr Huang Batt ch322 National Taiwan University (M.S.)
I am currently working in the Batt lab and investigating expression of SSX2 protein, a potential cancer tumor antigen for sarcoma, in E. coli and Pichia pastoris. My ultimate goal is to express SSX2 in these host strains with higher solubility or can be secreted extracellular for reducing the cost of the downstream processing while produced SSX2 in a large quantity.
Yongchao Li Wilson yl344 The Ohio State Univ. (M.S.)
I work in Dr. David Wilson's lab. The work in our lab focuses on cellulases. Currently, I have two projects to work on. First one, by studying the 3-D structure of Cel9A and using rational design method, we want to clarify the catalysis and processivity mechanisms of this cellulase. And the second one is to study the effect of cellulose structure and morphology on the activity of cellulases.
Courtney Lucas Wiedmann crl33 Miami University
I am a second year PhD graduate student in Martin Wiedmann’s lab working on virulence and ecology of Listeria spp. I graduated from Miami University in 2004 with a BA in Microbiology and Environmental Science. Currently in lab I am looking at virulence gene transcription in Listeria monocytogenes (foodborne pathogen) versus Listeria seeligeri (avirulent to humans) under different conditions using RT-PCR. I am researching why L. seeligeri contains all the virulence genes of L. monocytogenes, but is and what its potential host might be. I am continuing with intracellular growth assays comparing complementation mutants containing LS virulence genes in null LM strains. I also conduct field research in the Finger Lakes National forest looking at the prevalence and distribution of Listeria spp. in different environments.
Juliane Ollinger Boor jo76 Ernst-Moritz-Arndt-Univ. (M.S.)
I came from Germany to Cornell in order to do my PhD degree. I'm working in the food safety lab of Kathryn Boor in Stocking Hall. My research project comprised the virulence gene regulation in Listeria monocytogenes. Our lab discovered that there is a link between stress response regulation via sigma B and virulence gene regulation via PrfA. I try to find out in what way these two regulators work together in order to optimize invasion of the host cell by Listeria. The tools I'm using are real time PCR, microarrays and in vitro transcription assays.
Sarah Perdue Roberts sp366 Univ. of Wisconsin--Madison
Sarah Perdue is a second-year graduate student working with Dr. Jeff Roberts in the Department of Molecular Biology and Genetics. She graduated from the University of Wisconsin-Madison in 2002 with a B.S. in biochemistry. Her research project focuses on studying the regulation of E. coli RNA polymerase (RNAP) by the bacteriophage lambda late gene regulator, Q protein. At the lambda late promoter, pR’, Q becomes a stable part of the elongating transcription complex and modifies polymerase into a termination-resistant form. Specifically, she is using a set of mutant RNAPs that are resistant to Q modification and conducting a screen for mutations in Q which suppress the polymerase mutations. The results obtained from this screen will shed light on the physical interactions between Q and RNAP and how these interactions cause RNAP to be less susceptible to transcription terminators. Sarah is also actively involved in science outreach, most recently becoming involved with Cornell’s Graduate Student School Outreach Project (GSSOP), in which she developed a mini-course in genetics and biochemistry and taught it to local high school students.
Andrew Regan Whittaker adr32 Oregon State University
I am studying the entry mechanisms utilized by enveloped RNA viruses. Current work entails the generation of a monoclonal antibody library directed against HeLa cell surface proteins. The library will be used to screen for co-receptors of influenza and vesicular stomatitis virus.
Michie Sho D.Russell ms474 McGill University (M.S.)
I am in David Russell's lab. Our lab's focus is Mycobacterium tuberculosis and we try to elucidate anything about the bacterium from many different aspects including biochemistry, immunology, cell biology, genetics, and more. My main focus is in biochemistry of this bacterium. I am trying to elucidate what metabolic/catabolic pathways are induced in different environmental stimuli.
Leonardo Teixeira Batt lmt36 Univ. Federal de Viscosa (M.S.)
Leo Teixeira is a graduate student in Dr. Carl Batt's Lab. His undergraduate research centered studying the instability of a probiotic Lactobacillus (L. delbrueckii UFV H2b20). He related the lost of the imunoestimulation capacity with the lost of s-layer proteins in this microorganism. Recently, he is investigating bacterial surface layer (s-layer) proteins from prokaryotic organisms as scaffolds for nanofabrication. Part of this project involves the characterization of novel and useful s-layer proteins from different microorganisms, and the design of novel genetic constructions, varying the C- and N-terminal sequences of theses proteins to alter the ability of them to self-assemble, and bind in different surface. These structures would facilitate the optoelectronic characterization and manufacturing of nanoparticle and nanowire arrays.
