Elliot Crooke, PhD

Professor & Chair of the Department of Biochemistry and Molecular & Cellular Biology

Dr. Crooke, Professor and Chair of the Department of Biochemistry and Molecular & Cellular Biology, studies two areas of cellular biology. One is to determine molecular mechanisms that cells employ to assure that their genome is faithfully replicated once, and only once, per cell cycle. Loss of such mechanisms is one of the hallmarks of the onset of carcinogenesis. The second project in Dr. Crooke’s laboratory focuses on understanding the physiological role that cellular polyphosphates play in how cells respond to environmental stresses. These long, energy-rich polymers are found found in virtually all organisms. Disruption of the gene that encodes the polyphosphate biosynthetic enzyme, polyphosphate kinase (PPK), gives rise to cells that have decreased viability following exposure to environmental challenges such as heat, UV-irradiation and oxidativestress, or when the cells are maintained in the stationary phase for prolonged periods. Certain mutations elsewhere in the genome have the ability to suppress the sensitivities that ppk knock-out cells have toward these environmental stresses. Identification of the genes that harbor such mutations will help us understand in which signal transduction and stress response pathways polyphosphates participate.

Albert Fornace, MD

Molecular Cancer Research Chair, Lombardi Comprehensive Cancer Center
Professor, Department of Biochemistry and Molecular & Cellular Biology

Albert J. Fornace Jr., MD, is the Molecular Cancer Research Chair at Lombardi Comprehensive Cancer Center; Professor, Department of Biochemistry and Molecular & Cellular Biology. Most of us are all too familiar with the effects that psychological stress can have on our bodies. But Georgetown University Medical Center’s Dr. Fornace, Professor of Biochemistry and Molecular & Cellular Biology and Oncology, is committed to researching how environmental stresses can cause normal cells to become cancerous—and is developing ways to stop this from occurring or to exploit differences between normal and malignant cells therapeutically. Fornace’s innovative work in the area of cellular responses to radiation and other environmental toxins has earned him the Molecular Cancer Research Chair at the Lombardi Comprehensive Cancer Center. Fornace, the first recipient of the Chair, joined Georgetown in 2006 from the Harvard School of Public Health, where he was the director of the John B. Little Center for the Radiation Sciences and Environmental Health. As the Molecular Cancer Research Chair, he is investigating what happens to cells when they are stressed or injured–by anything from toxic substances to aberrantly expressing oncogenes–work that has thus far revealed processes underlying development of cancer and other diseases. Fornace’s research has shown that diseases develop when stress-related signals inside the cell alter the expression of multiple genes involved in cell-cycle control, programmed cell death, and DNA damage processing. In addition to his research on the molecular pathways of cancer, Fornace is also studying cellular stress responses on a broader level. By understanding genome-wide response to stresses like radiation or chemical toxins, Fornace will be able to develop biomarkers to detect exposure in humans. He is specifically looking for markers in both gene expression and metabolites which can be detected in easily obtainable samples like urine, blood, and saliva. With this kind of test available, emergency response personnel would be able to identify and triage patients who were significantly exposed. Additionally, Dr. Fornace is the co-director of the Center of Innovation at Georgetown University. This Waters Corporation program acknowledges and supports innovations and breakthroughs in health and life science research, such as has been demonstrated through Dr. Fornace’s work and the metabolomics program at Georgetown University.

Mehmet Kayaalp, MD, PhD

Mehmet Kayaalp’s work focuses on computational linguistics, machine learning and probabilistic graphical models on the domain of medical informatics. He has published a number of articles on each of these subjects. He leads NLM efforts on de-identifying narrative clinical reports.

Dr. Kayaalp started working on biomedical informatics projects in the mid-1980s during his medical education at the University of Istanbul, from which he received his MD. He pursued his interest in biomedical informatics as a research scholar at Southern Methodist University in Dallas, Texas. He later matriculated at SMU, where he earned an MS in Computer Science, and successfully completed his PhD coursework and doctoral exams. Toward his dissertation work, he worked on an Office of Naval Research-funded computational linguistics project, developing various probabilistic linguistic models based on Markov random field theory. Upon the departure of his advisor from SMU, Dr. Kayaalp moved to the University of Pittsburgh, where he worked with Drs. Gregory F. Cooper and Bruce G. Buchanan on Bayesian networks and machine learning in various biomedical informatics projects. He received his Ph.D. degree in Intelligent Systems from University of Pittsburgh with a specialization in Biomedical Informatics.

Dr. Kayaalp has worked on various software engineering projects during his career but his main interest has remained artificial intelligence. In the 1990s, he developed the concept of multifaceted ontological networks, by recognizing the fact that everyone cannot agree on a single scientific or philosophic view of the world, but multiple views and interpretations of the same world have to coexist and compete for the progress of science and culture. The method of multifaceted ontological networks is a means to cope with the exponential growth of scientific information. It proposes a systematic organization of scientific information from various disciplines through a non-ambiguous formalism of logic without excluding any particular scientific observation or interpretation of the world.

Professional Activities: 

Dr. Kayaalp was appointed as the physician and the chief medical officer to a transportation regiment, where he managed the operation of an Army clinic supervising other medical and Army personnel. In the early 1990s, he worked as a research scholar in the Department of Computer Science and Engineering at Southern Methodist University, Dallas, Texas. During his studies in computer science, he worked at SMU in various academic capacities including teaching and research positions. In University of Pittsburgh, he worked at the Center for Biomedical Informatics, (currently known as the Department of Biomedical Informatics), where he participated as a research assistant to the Integrated Advanced Information Management Systems project funded by National Library of Medicine.
