Biomedical-related resources available through the College of Engineering (CoE) are separated into 4 primary areas: general prototyping facilities, bioinformatics (including signal processing and data mining), applied biomedical engineering laboratories (including nanotechnology), and additional capabilities.
General Prototyping Facilities
Several facilities exist within the College of Engineering for prototyping new devices. These include Rapid Prototyping Facilities located within the Department of Industrial Engineering which houses a 3-dimensional thermoplastic printer (Thermojet Multi-Jet Modeling) with a 300 x 400 x 600 dpi resolution and a maximum model size of 10 x 7.5 x 8 inches. Capabilities of the Department of Biomedical Engineering’s prototyping instrument (Prodigy Plus Strata Systems) include a resolution of 143 dpi and a maximum size of 8 x 8 x 12 inches. The College of Engineering also has a 2,990 square feet machine shop fitted with a large assortment of hand and power tools plus heavy equipment, including hydraulic presses, vertical and horizontal band saws, motorized sanders, sand blasting equipment, engine lathes, vertical and horizontal milling machines (which are computer controlled), grinders, drill presses, and prototype finishing equipment (buffer, polisher, wire wheels). The machine shop is also fitted with specialty equipment designed to work with sheet metal (a hydraulic shear, a manual shear, Bead and Spartan roller, notcher, hole puncher, and ornamental bender), welding (miller, arc welder, spot welder, oxygen/acetylene cutting and brazing, and steel deck welding table with vise) and carpentry (table saws, band saws, scroll saw, miter saw, and disc sander).
A considerable amount of intellectual and computer resources are available through the Department of Electrical and Computer Engineering in the area of Bioinformatics which includes electronic medical records management, biomedical signal processing, and data mining. The intellectual resources applicable to research at the medical school include for example the research conducted by Shyu, who has developed techniques to analyze the huge amounts of data to support large-scale information systems in medical and bioinformatic domains. The developed techniques have been applied to electronic medical records (EMRs) such as the anesthesia information systems and the intestine transplant information systems, all to extract useful patterns/knowledge to improve clinical decision-making, adherence to guidelines, and/or patient safety. She has used feedback control techniques to build a predictive model to guide the use of appropriate anesthetic approaches in real-time during labor and delivery and to locate the protein-protein interaction networks involving neuronal and glial cells of the central nervous system (CNS). Premaratne has expertise in data mining from imperfect data streams and databases which are critical when evaluating medical records as medical/healthcare databases are often poorly maintained and are rife with data imperfections. They often contain unstructured text statements (e.g., physician notes about a patient) and expert opinions (e.g., subjective opinions of physicians) that cannot be captured via traditional probabilistic models. The evaluation of imperfect data has been used to develop novel machine learning techniques in the context of the diagnosis and treatment of HIV patients (Kubat). In addition to data mining, Kubat is widely respected as a pioneer of the fields of induction in time-varying domains and machine learning from imbalanced classes. Cai applies statistical signal processing methods, machine leaning and pattern recognition, dynamical system and control theory to molecular biology. His current interests focus on stochastic modeling and simulation of gene networks, inference of gene networks, multiple QTL mapping and genome-wide association studies. Abdel-Mottaleb works in the area of image processing, computer vision and pattern recognition. He has been active in the area of biometrics, especially face recognition, ear recognition and human recognition from dental X-ray images. Younis has focused on the development of information integration approaches for distributed genomic data sources in a grid environment. He has collaborated with others in investigating effective techniques for genome-wide analysis that are applicable in personalized medicine. In biomedical imaging, Younis has developed novel approaches for detection and quantification of neuro-degenerative diseases, specifically Multiple Sclerosis and HIV-associated neurological disorders.
