research overview

Professor Richardson has biomedical engineering research interests with five main themes: adhesion, aggregation and disintegration of cells and cell groups, with applications in thrombosis and hemostasis; artificial organs, especially those designed for transport purposes such as artificial lungs and hybrid artificial pancreases; applications of ultrasound in detection and diagnosis, including intravascular usage, and corresponding image analysis; interaction of flow and blood vessel walls, especially for problems associated with atherosclerosis; design of devices and instruments with biomedical applications (where his research has led to patents).

research statement

Professor Richardson has biomedical engineering research interests with five main themes: adhesion, aggregation and disintegration of cells and cell groups, with applications in thrombosis and hemostasis artificial organs, especially those designed for transport purposes such as artificial lungs and hybrid artificial pancreases applications of ultrasound in detection and diagnosis, including intravascular usage, and corresponding image analysis interaction of flow and blood vessel walls, especially for problems associated with atherosclerosis design of devices and instruments with biomedical applications (where his research has led to patents). One current project illustrating a combination of the third and fourth themes is a study of the left anterior descending epicardial arteries in pigs which have been fed atherogenic diets, making comparisons between video-rate intravascular ultrasound images at various mean blood pressures (using image-analysis software custom-written at Brown), mechanical measurements of tissue obtained immediately at post-mortem, and histology of the vessel sections, with relevance to improvement of coronary angioplasty. Another current project involves computer-modeling of flow of thousands of blood platelets as they join a developing thrombus, under various conditions of flow, and incorporating time-varying physiological responses of the individual platelets. Professor Richardson also has engineering research interests which are not primarily biomedical, these having two main themes: (a) effects of oscillations, pulsations, sound and vibrations on flow fields, and corresponding heat and mass transfer (b) flows at branches of tubes and ducts, including cases where the flows are oscillatory or pulsatile
