Steven Soper, Ph.D.

Professor Steven A. Soper received his Ph.D. from the University of Kansas in 1989, followed by a Postdoctoral Fellowship at Los Alamos National Laboratory, where he worked on single-molecule detection for high speed sequencing of the human genome. In 1991, he joined the faculty at Louisiana State University, LSU, within the Department of Chemistry, where he filled the William H. Pryor Distinguished Chair of Chemistry. Professor Soper also held joint appointments in the Mechanical Engineering Department and Department of Biological Sciences. While at LSU, he founded the Center for BioModular Multi-Scale Systems, which has as its primary charge to develop enabling and transformative tools for making health-related measurements at unprecedented speeds with full process automation directly at the Point-of-Care. Some of these tools include integrated systems for determining bacterial/viral infections of unknown strains in patients, evaluating brain damage/injury, sampling blood for rare cells such as circulating tumor cells and their molecular analysis, and sequencing genomes in near real time. These tools consist of microfluidic and nanofluidic devices made in polymers via micro- and/or nanoreplication.

David Kaufman, M.D., Ph.D.

Professor David G. Kaufman majored in Physics as an undergraduate at Reed College. He received his M.D. from Washington University School of Medicine (St. Louis, Missouri) in 1968; and his Ph.D. in Experimental Pathology (with an emphasis on molecular biology) in 1973. He did his residency training in Anatomic Pathology at Barnes-Washington University Hospital. He did postdoctoral training at the National Institutes of Health (Bethesda, Maryland), focusing on lung cancer and DNA replication research. He was recruited to the Department of Pathology at the University of North Carolina in 1975 and he has remained there to the present. He is currently Professor in the department and formerly was Vice Chair. Throughout this interval Dr. Kaufman has practiced medicine as an attending anatomic pathologist at the University of North Carolina Hospitals. Concurrently, he pursued an active and diverse research program. Related to clinical service in gynecologic oncologic pathology, he participated in an epidemiologic study of the relationship between post-menopausal estrogen therapy and endometrial cancer. This study provided powerful evidence that estrogen therapy caused endometrial cancer. In a subpopulation of this study patients that received progestins in addition to estrogen he recognized that progestins not only eliminated the excess risk from estrogen but actually lowered the risk below that of controls who were not taking hormones. Based on his interest in endometrial cancer he studied human endometrial tissue in organ and cell culture. Eventually he was able to reconstitute human endometrial tissue in co-cultures with the morphology of endometrial tissue in vivo and the ability to respond to hormones with physiologic changes characteristic of the menstrual cycle. Other studies revealed that the mitogenic effects of estrogen on endometrial epithelial cells involved paracrine responses resulting from estrogen effects on co-cultured endometrial stromal cells.

He also studied the relationship between the cell cycle and carcinogenesis. He showed that synchronized cells were most vulnerable to malignant transformation when treated with chemical carcinogens as they entered the S-phase of the cell cycle. He also showed that DNA at the site of replication was exquisitely vulnerable to attach by chemical carcinogens. In efforts to characterize DNA replication and repair the adopted single fiber (molecule) analysis, tracing the localization of newly replicated DNA and DNA damage sites tagged with fluorescent probes.

Dr. Kaufman has received many extramural grants from the NIH to support his research, to support graduate and postdoctoral training and to purchase high end common-use equipment. He has published nearly 200 papers and book chapters. He has trained 12 students granted PhDs and about 40 postdoctoral trainees.
Dr. Kaufman has served in a number of capacities in national societies and advisory bodies. He was a committee member, committee chair and council member for grant awarding agencies, including the NIH, National Cancer Institute and the American Cancer Society. He was a member of several scientific committees of the National Research Council, National Academy of Sciences, and the International Agency for Research on Cancer. He served on the EPA’s Science Advisory Board and on the Advisory Board of the Association of American Medical Colleges. He was President the leading society in his discipline, the American Society for Investigative Pathology. Later, he was President of the Federation of American Societies for Experimental Biology, which represents nearly 100,000 scientists.

Dr. Maggie A. Witek received her MSc. and Engineering degree from the Department of Chemistry and Chemical Technology at Silesian University of Technology in Gliwice, Poland in 1997. She earned her Ph.D. in Analytical Chemistry from Michigan State University in 2002 under tutelage of Prof. Greg M. Swain. Her doctoral work focused on the development of microcrystalline and nanocrystalline boron-doped diamond thin film electrodes for electrochemical detection of biogenic compounds.

Dr. Witek joined Prof. Steven A. Soper’s research group in the fall of 2002 in the Department of Chemistry at Louisiana State University, Baton Rouge. Her postdoctoral work focused on controlled biological cell transport via electromigration in thermoplastic microfluidic devices and development of the on-chip solid-phase extraction platform for nucleic acid isolation. In 2004 Dr. Witek joined the NSF EpSCOR funded Center of BioModular Multiscale Systems (CBM2) at LSU as a Research Associate. She continued research on applications of polymer-based, lab-on-a-chip devices for biomedical applications, such as the separations, high throughput solid-phase nucleic acid purification and molecular testing (i.e., PCR, LDR, microarrays). Dr. Witek established a working group for students, post-doctoral fellows, and professors organizing Professional Development Seminar Series in the Department of Chemistry and CBM2. Monthly meetings for chemistry, biochemistry, and engineering fellows ranged in different topics, from traditional research seminars to informal discussions with young faculty sharing their academic experiences, inviting entrepreneurs to talk about opportunities in industrial-academic collaborations, and hands-on workshops on resume writing and effective presentation skills. This working group allowed for scholars to discuss new research ventures and build a network throughout the university.

In 2011 Dr. Witek joined the Department of Biomedical Engineering at the University of North Carolina in Chapel Hill as an Assistant Research Professor. The main focus of her work at UNC was collaboration with oncologists at the UNC School of Medicine and development of the assay for isolation of low abundant subpopulations of circulating tumor cells from clinical samples using antibody modified microfluidic devices.

Dr. Witek is currently an Associate Research Professor in the Department of Chemistry at the University of Kansas in Lawrence. Her research involves microfluidic-based isolation of liquid biopsy markers, including circulating tumor cells followed by molecular profiling and sequencing of these cells’ DNA/RNA; selection of extracellular vesicles and cell free DNA for stroke and cancer diagnostics. She continues her work in the NIH/NIBIB funded Center of BioModular Multiscale Systems for Precision Medicine as an investigator and coordinator of the Center’s Collaborative and Service Projects. As a result of her research efforts, Dr. Witek has published over 40 peer-reviewed manuscripts and book chapters.

Dr. Witek developed a diverse background from extensive collaborations with chemists, biologists, and engineers at LSU, oncologists at the UNC School of Medicine and KU Medical Center in Kansas City, KS. She uses her expertise to organize training and dissemination programs in the CBM2 for individuals with various levels of technical competency in the micro/nanofluidic field.
