SPEAKER BIOGRAPHIES: Higher Throughput Protein Purification

Joshua LaBaer, M.D., Ph.D., Virginia G. Piper Chair in Personalized Medicine, Director, The Biodesign Institute; Personalized Diagnostics, Arizona State University
Joshua LaBaer, M.D., Ph.D., formerly the Director of the Harvard Institute of Proteomics (HIP), is the Piper Chair in Personalized Medicine, Director of the Virginia G. Piper Center for Personalized Diagnostics and the Chair of the Directorate of the Biodesign Institute. His efforts involve leveraging the Center's formidable resources for the discovery and validation of biomarkers—unique molecular fingerprints of disease—which can provide early warning for those at risk of major illnesses, including cancer and diabetes. He completed medical and graduate school at the University of California, San Francisco where he studied steroid regulation of DNA transcription and protein-DNA interactions. He completed his internship and residency at the Brigham and Women's Hospital and a clinical fellowship in Oncology at the Dana-Farber Cancer Institute in Boston. Dr. LaBaer is a member of the National Cancer Institute Board of Scientific Advisors. Recently he was elected Chair of the EDRN Executive Committee and Co-Chair of the Steering Committee. Dr. LaBaer serves as an associate editor of the Journal of Proteome Research, and a member of the editorial boards of Analytical Chemistry, Current Opinion in Biotechnology, Cancer Biomarker, Molecular Biosystems, and Clinical Proteomics. He is treasurer and president-elect for US Human Proteome Organization (USHUPO) and a member of the Scientific Advisory Committee for Plexera.

Guy Poirier, Ph.D., Canada Chair, Targeted Proteomics, Laval University and Chuq Research Center, Quebec
Dr. Guy G. Poirier holds a Tier 1 Canada Research Chair in targeted proteomics and is full professor at the Faculty of Medicine, University Laval, Quebec, Canada. Professor Poirier is interested in two main research fields: apoptosis and proteomics. He is a leader in the field of proteomics of poly(ADP-ribose) binding protein and a specialist in the study of DNA damage sensing enzymes (PARP) that play a fundamental role in signaling DNA damage and in its repair. A better understanding of DNA damage signals and of a phenomenon known as apoptosis (programmed cell death) will greatly improve the diagnosis and treatment of widespread diseases such as cardiovascular disease, diabetes, neurodegenerative diseases and several types of cancer. As a matter of fact, PARP inhibitors are used successfully in cancer therapy. His work on poly(ADP-ribose) has led to major discoveries on the role of PARPs in apoptosis (involvement and discovery of caspases), DNA repair and stability of genome integrity (Lazebnik et al 1994 Nature, cited 1200 times; Rouleau et al, Nature Cancer Reviews, 2012). In 2006, in collaboration with the Dawson's group at Johns Hopkins University, he developed for the first time a PARG-deficient mouse. This genomic disruption delays the nervous systems development and is lethal at the embryonic stage. The two groups also studied the critical role of AIF in cell death in the nervous system and of E3 ligase RNF146 (published in Nature and Science). Concurrently, Dr Poirier has developed a proteomics platform. At the international level, in 2010, Dr Poirier was the founding president of CNPN (Canadian National Proteomic Network) which organizes key meetings at national and international levels (HUPO, Human Proteome Organization).

Douglas MacDonald, M.S., Senior Process Development Engineer II, Purification Process Development, Dendreon Corp.
Doug MacDonald graduated with a M.S. in Chemical Engineering from the University of Washington in 2000. He began his career at Immunex where he contributed to the successful implementation and scale-up of a post-capture refolding step of an Fc:fusion protein. After Immunex was acquired by Amgen, he continued work on the purification process development of four mAbs. Doug is very interested in new technology development, including custom resins and charged filters and had dedicated a significant amount of time to the area of high throughput screening (HTS) in downstream process development. Upon joining Dendreon in 2009, he brought the HTS technology to the forefront and has led the efforts in making this technology a practical alternative to initial downstream process development. He currently leads process development projects using 96-well filter plates and RoboColumns, and has used this technology to troubleshoot commercial processes.

W. Clay Brown, Ph.D., Scientific Director, High-Throughput Protein Lab, Center for Structural Biology, Life Sciences Institute, University of Michigan
I earned my Ph.D. at Wayne State University in Detroit and did a post-doc at the California Institute of Technology before beginning my career at Amgen in the Bacterial Expression department. At Amgen I worked on the development of proprietary systems for the production of biotherapeutic targets in bacteria. I then established an insect cell production lab supporting structural biology and high-throughput screening efforts. I later moved to Pfizer to become the head of Expression Technologies at the Ann Arbor site. At Pfizer I directed three separate groups producing reagents in bacterial, insect, and mammalian systems responsible for all in-house protein and cellular reagent provision for this site. I was also responsible for overseeing development of formats suitable for automation and headed a team identifying and implementing automation and technologies for optimizing bioprocesses. Now at the University of Michigan, I am Scientific Director of the High-Throughput Protein laboratory in the Center for Structural Biology. The mission of this lab is to provide services and support to life sciences researchers across the campus for the identification of constructs and conditions that lead to high yields of soluble protein expression in bacteria, insect cells and we are just launching a mammalian service. I also pursue basic research into developing molecular biology tools such as ligation-independent cloning vectors compatible with each system, alternative promoters and solubilizing fusion partners.
