John Brash, Distinguished University Professor, McMaster University, Hamilton, Ontario, Canada.

Interests: biomaterials, blood-material interactions, blood compatible materials, surface modification.
The group of Professor Brash works on biomaterials and biocompatibility with emphasis on materials for use in contact with blood. A major limitation in these situations is the formation of thrombus, the initiating event being the adsorption of proteins at the blood-material interface. Accordingly the behaviour of proteins at interfaces is an important underlying theme of our work. The design of surfaces based on controlling protein interfacial interactions in blood is also a major theme. Examples are surfaces that prevent protein adsorption entirely, and surfaces that “select” for specific proteins such as antithrombin to inhibit coagulation, and plasminogen/t-PA to promote fibrinolysis.

Lawrence F. Brass, MD PhD, Professor of Medicine, Professor of Systems Pharmacology and Translational Therapeutics, University of Pennsylvania, Perelman School of Medicine, Philadelphia, Pennsylvania

Interests: platelet activation, signal transduction networks, applying systems approaches to hemostasis and thrombosis.
Current efforts in the group of Dr. Brass focus on understanding the molecular events that underlie platelet activation and the conversion of circulating platelets to fully adherent platelets using human and mouse models. Increasingly, this means using a systems approach to combine data on the platelet signaling network with emerging ideas about platelet activation as it occurs in the complex environment found in vivo under both normal and pathological conditions.

Interests: Development and application of ultra-high vacuum applying analytical techniques to biomedical problems. Surface Analysis; Surface Modification; Biomaterials; Mass Spectral Imaging.
The work in prof. Gamble's group focuses on the development of techniques (sample preparation, technique development, data processing, and data analysis) for analysis of biomolecule-surface interfaces and chemical imaging of biologically relevant samples. Using imaging secondary ion mass spectrometry, 3D images of cells at sub-cellular resolution and with chemical specificity can be obtained. This opens up a range of possibilities for better understanding and diagnosing biological processes such as tumor microenvironments, lipid metabolomics relationship to cancer, tissue repair, and chemical analysis of tissue and/or cells on a cellular and sub-cellular level.

Maud Gorbet, Professor and Chair, Biomedical Engineering, University of Waterloo, Waterloo, Ontario, Canada

Interests: Understanding the interaction of biological and biomaterial systems at the cellular level. Biocompatibility with biomaterials and biomedical devices. Mechanisms of material-induced thrombosis (blood clot formation) with mechanical heart valves and coronary stents. Ophthalmic biomaterials (such as soft contact lenses and keratoprosthesis).
While biomedical devices have significantly improved quality of life and increased life expectancy of millions of people, their use is fraught with complications such as infection (vascular grafts, contact lenses), thrombosis (blood clot formation on cardiovascular devices such as mechanical heart valve) and fibrosis (orthopaedic implants, glaucoma shunts). Although the overall rate of complications remains low, the consequences are often grave and constly. Research in Prof. Gorbet's laboratory aims to understand interactions between biomaterials and biological systems. A better understanding of the mechanisms of material-induced cellular activation will enable the design of materials and/or therapeutic strategies that improve biocompatibility and hence reduce the risks of complications and failures.

Interests: Synthesis and characterization of polymeric biomaterials. Surface analysis by ESCA, SIMS, STM, FTIR-ATR, AFM. Plasma deposition of thin films. Tissue engineering. Blood-material interactions.
Medical devices and implants are engineered from specially designed materials, often referred to as biomaterials. Millions of devices and implants are used clinically in applications as diverse as blood vessel replacements, catheters, contact lenses, hip joints, ventricular assist devices and artificial kidneys. The biocompatibility of these prostheses is dictated by their surface properties and by the local mechanical environment they induce. In my research program, biomaterials are engineered to control biological interactions, synthesized, characterized and observed during interaction with biological systems.
