UNC/NC State Joint Department of Biomedical Engineering

Dr. Jacqueline (Jacque) Cole

Assistant Professor
PhD (2007), Cornell University

Research Interests: Bone mechanics, bone-vascular interactions, aging, fracture, stroke, exercise and aerobic metabolism

Cole received a BME in mechanical engineering in 2001 from Auburn University. She was named the Outstanding Co-op Student of the Year in 2000 for her work experience in manufacturing. She received an MS in 2004 and a PhD in 2007 in mechanical engineering from Cornell University, where she specialized in the biomechanics of aging human bone. She was a postdoctoral research fellow in chemistry at the University of Michigan and was awarded a National Institutes of Health Ruth L. Kirchstein National Research Service Award in 2008, 2009 and 2010. She recently completed a second postdoctoral fellowship in orthopaedic surgery at the University of Michigan. Cole has extensive experience in whole bone and tissue mechanics, tissue composition, cellular (osteoblast) activity, and bone imaging and diagnostics.

The overall goal of Cole’s research is to improve current strategies for treating bone loss with aging, disease (e.g., cardiomyopathies, diabetes), and other conditions such as stroke by examining bone-vascular interactions and their influence on bone mechanics and bone cell function. Specifically, her lab is focused on developing imaging protocols to characterize changes in bone and vascular morphology and structure, monitoring activity in bone and vascular cells, and exploring potential mechanisms for these changes using animal models. Understanding more about the effects of bone-vascular interactions on bone properties and how they are altered with various conditions and treatments will provide insight into better therapeutic strategies to minimize bone loss and maintain skeletal integrity.

Dr. Blair D. Sullivan

Assistant Professor
PhD (2008), Princeton University

Research Interests: Graph algorithms, parallel and high-performance computing, applied structural graph theory, combinatorial scientific computing, and graph embeddings for quantum computing

Sullivan received her BS degrees in applied mathematics and computer science from the Georgia Institute of Technology, supported as a President’s Scholar. She received her PhD in mathematics from Princeton University, where she held a US Department of Homeland Security Graduate Fellowship and Dissertation Grant. During her tenure at Princeton, she also spent time as a visiting researcher at the Renyi Institute in Budapest, Hungary, and held internships with Oak Ridge National Laboratory (ORNL) and Microsoft Research’s Theory Group in Redmond, Wash. Prior to joining the NC State faculty, she was a computational mathematician in the Computer Science and Mathematics Division at ORNL, where she was principal investigator on grants from the Department of Energy’s Office of Advanced Scientific Computing Research, DARPA GRAPHS, and ORNL’s LDRD program.

Sullivan’s recent work focuses on integrating tools and techniques from structural graph theory into tools for scalable network analysis. One focus is on elucidating and utilizing tree-like “intermediate scale” structure in complex networks (e.g., hierarchies in biology, hub nodes in social networks, or hyperbolic routing in the Internet) to enable scalable analysis and expand the types of queries possible on massive graphs. This includes developing new algorithms/implementations for solving optimization problems using tree decompositions and dynamic programming on parallel/HPC architectures, integrating structural graph theory constructs with ideas from hyperbolic geometry to define an intermediate scale “skeleton” for networks, and developing approaches to dimensionality reduction that take advantage of network structure and avoid densification of sparse graph data. She also works on designing measures of graph similarity, and mathematical evaluation of random graph generators to improve network modeling.

Dr. Maria E. Mayorga

Associate Professor
PhD (2006), University of California, Berkeley

Research Interests: Predictive models of health outcomes, application of stochastic optimization in production and service systems with emphasis on health care services, modeling marketing and operations interface, and analysis of queuing systems

Mayorga received her PhD in industrial engineering and operations research from the University of California, Berkeley. Prior to joining the NC State faculty, she was on the faculty at Clemson University in the Department of Industrial Engineering for seven years.

She has authored more than 40 publications in archival journals and refereed proceedings. Her research has been supported by the National Institutes of Health and the National Science Foundation, among other sources. She is a member of INFORMS and the Institute of Industrial Engineers and area editor for the journals Health Systems, IIE Transactions and IIE Transactions on Healthcare Systems Engineering.

Mayorga’s main research interests can be divided into two areas: predictive models of health and economic outcomes and optimal resource allocation in emergency medical service (EMS) systems. In the first area, she combines statistical methods and simulation to make predictions about the progression and impact of a disease (e.g., diabetes) or behavior (e.g., drinking during pregnancy) at the population level and over long periods of time. Most recent efforts focus on assessing the effectiveness of colorectal cancer screening by considering patient choice and adherence to screening options. In the second area, she focuses on optimally (or near optimally) locating and dispatching EMS vehicles while introducing some of the complexities of real-world systems often overlooked in the literature; for example, revised decisions given that new information becomes available on-scene.
