Biography
Dr. David A. Boothman is Professor of Pharmacology and Radiation Oncology. Dr. Boothman is a senior leader in the Simmons Comprehensive Cancer Center, serving as Associate Director for Translational Research and co-Director of Experimental Therapeutics. He developed the Laboratory Correlates Group (LCG) and Biomedical Research Core (BRC) infrastructure with Dr. David Gerber. Dr. Boothman works closely with all ET Program themes to promote preclinical and clinical translation. He aids in the development of infrastructure needed for standardized pharmacodynamic (PD) lab correlates. Dr. Boothman also co-leads (with Dr. Jinming Gao) a Cancer Nanomedicine Group within the SCCC. He has been funded by the NIH for the past 27 years, is elective representative for FASEB for the Society of Experimental Biology, and is currently a permanent member of the Radiation Therapy and Biology (RTB) NIH study section. His current research projects include: (a) Use of NQO1 bioactivatable drugs for therapy of human solid NQO1+ cancers; (b) Use of NQO1 bioactivatable drugs to promote the tumor-selective use of DNA repair inhibitors, such as PARP inhibitors; and (c) Elucidating the roles of RNA termination factors for R-loop resolution, DSB repair defects, genetic instability and cancer vulnerabilities. His lab is currently funded by the NIH (2), two grants from the AACR/Pancreatic cancer action network (PanCan) and the Alex Lemonade Society (in collaboration with Drs. Ted Leatsch and James Amatruda).

Biography
Dr. Saurabh Chawla did his medical school and surgical residency in New Delhi, India at the University of Delhi, which is recognized as one of the top medical universities in India. After coming to the US, he did his Internal Medicine residency at the famous Cook County Hospital in Chicago, IL where he won numerous awards for academic and clinical excellence. He then went on to become the Chief Medical Resident at Cook County which is one of the largest and the busiest clinical training programs in the country. He stayed on in Chicago to complete his gastroenterology fellowship training at Cook County following which he came to the Emory University School of Medicine for additional training in Interventional Endoscopy. He is currently faculty at the Emory University School of Medicine and the director of interventional endoscopy at Grady Memorial Hospital in Atlanta. Dr. Chawla is an academic gastroenterologist actively involved in Medical School teaching, resident and fellow training in Gastroenterology and clinical research. He has several original publications including research studies, review articles and book chapters and has presented extensively at various national and international conferences. He is on the editorial board of a gastroenterology journal and committees of various national and regional gastroenterology societies.
Research Interest
His clinical interests include medical education, pancreaticobiliary diseases and malignancies, and inflammatory bowel disease.
Biography
Dr. Nicholas Zavazava's work primarily focusses on stem cells. His lab is interested in studying stem cell derived hematopoietic cell and insulin producing cells. Type 1 diabetes is one of the most devastating chronic diseases which costs billions of dollars every year. By establishing a stem cell based source of insulin producing cells, they belive they might be able to treat many patients who would otherwise remain untreatable. Embryonic stem (ES) cells and induced pluripotent stem (iPS) cells possess an unparalleled characteristic of being pluripotent and therefore able to differentiate into progenitor cells of any cell type. Their laboratory seeks to exploit this property and derive hematopoietic cells and insulin producing cells from human ES and iPS cells. More importantly, they are interested in determining whether these cells are rejected in both the syngeneic and allogenic setting. Using proteomics, they have discovered a “stem cell factor†that is only produced in vivo by the progenitor cells leading to recruitment of NK cells and rejection of the progenitor cells. A second aspect that they are interested in is to coax human iPS cells to differentiate into insulin producing cells for the treatment of diabetes. They are working on how they can convert near 100 % of the iPS cells into Pdx1-expressing cells that further differentiate into insulin producing cells. Pdx1 is a pancreatic transcription factor that regulates pancreatic development. Our goal is to establish iPS cells as a novel source to treat diabetes reducing the management costs of diabetic patients.
