Gail D. Baura, PhDProfessor, Medical Devices
Medical Devices, Machine Learning, Engineering Ethics
Dr. Gail Baura received a BSEE from Loyola Marymount University in 1984, and an MSEE and MSBME from Drexel University in 1987. She received a PhD in bioengineering from the University of Washington in 1993. Between these graduate degrees, Dr. Baura worked as a loop transmission systems engineer at AT&T Bell Laboratories. Since graduate school, she has served in a variety of research and development positions at IVAC Corporation, Cardiotronics Systems, Alaris Medical Systems, and VitalWave Corporation (now Tensys Medical). Her most recent industrial position was Vice President of Research and Chief Scientist at CardioDynamics. In 2006, she returned to academia.
Dr. Baura is a senior member of IEEE, an associate editor of IEEE Engineering in Medicine and Biology Magazine, an ABET Engineering Accreditation Commissioner (EAC) representing the Biomedical Engineering Society, and an ABET program evaluator for bioengineering and biomedical engineering. She holds 20 issued U.S. patents. Dr. Baura has written four engineering textbooks on medical devices and engineering ethics. As the author of the first textbook in her specialty (system theory applied to patient monitoring), she serves as an intellectual property expert witness for medical device companies in her field. As the sole expert witness for Masimo Corporation, she provided technical expertise in three separate patent interferences that resulted in the cancellation of four Nellcor Puritan Bennett (Tyco) U.S. Patents.

Physiologic signals provide a wealth of information that can be used to develop new medical devices. These signals can be harnessed to enable diagnosis and monitor various conditions. Because the clinical usage requirements for patient monitoring and diagnostic devices are so high, Dr. Baura utilizes system theory, the transdisciplinary study of the synthesis and design of systems and the analysis of their performance , as the preferred substitute for heuristic, empirical processing. Dr. Baura has successfully applied a basic "toolkit" of system theory algorithms to a variety of signals related to large volume infusion and syringe pumps, electrocardiographs, noninvasive continuous blood pressure monitors, noninvasive continuous cardiac output monitors, electronic thermometers, electroencephalographs, external defibrillators, and pacemakers.
Dr. Baura divides system theory algorithms into three categories: filtering, modeling, and control. Since the hospital environment is an infinite source of signal distortion, filtering is a necessary requirement before digital signal processing and/or control can be applied to a signal of interest and may include the pseudorandom binary sequence, adaptive filtering, time-frequency analysis, and time-scale analysis. Once a signal of interest has been sufficiently filtered, it may be modeled to enable signal classification, prediction, control, and investigation of underlying physiologic mechanisms. Typical approaches include the ARMA (autoregressive with moving average and exogenous input) model, artificial neural networks, and fuzzy models.
Current Research Projects
Research in the Baura lab is focused on a new sensor and detection algorithm for drowsiness monitoring and on efficient methodologies for identifying candidate biomarkers for obesity.
Future Research InterestsThe Baura Lab is looking for collaborators at public universities who are interested in the retention rates of women in engineering.
