The Cardiac Optogenetics and Optical Imaging Lab conducts highly interdisciplinary work developing and applying optical technologies to tackle bioelectricity problems. Specifically, researchers work on biophysical aspects and technological innovations for a new highly-parallel framework for all-optical cardiac electrophysiology in vitro and in vivo. Guided by their own theoretical/computational work in the area of bioelectricity, they experimentally integrate, test and validate new optical and optogenetic modalities for actuation (stimulation) and sensing (optical mapping) of the electromechanical function in cardiac cells and tissues. This includes pioneering work in cardiac optogenetics: the use of light for the precise interrogation and control of cells and tissues with genetically-inscribed light sensitivity, ex vivo or in their native setting.

Li Lab – Nanophotonics and Microfluidics
Current research in the Li Lab focuses on the integration of nanophotonics and microfluidics, i.e. optofluidics, for biomedical applications. In optofluidic devices, not only the microfluidic liquid manipulation enables novel nanophotonic properties, but also the on-chip integration of photonic and microfluidic functions can lead to highly compact and integrated biosensing devices. There is a growing need to integrate photonic components with fluidic functions on the same substrate to build miniature optical sensing, imaging, and spectroscopy devices for medical diagnostics, environmental monitoring, and bioterrorism detection. As a nascent field, optofluidics offers many opportunities awaiting exploration and holds great potential to help realize the long-sought dream of integrated lab-on-a-chip systems, i.e. medical tricorders.

The Kay Lab of Cardiac Research
Professor Kay's research group develops innovative technologies to study hypoxia, heart failure, and sleep apnea, with an emphasis on mitochondrial function, arrhythmia mechanisms, and recent emphasis in neurocardiology. The lab's expertise is in high-speed optical assessments of organ level physiology, including optical mapping, time-resolved absorbance spectroscopy, and neurocardiac optogenetics. For example, panoramic optical mapping of membrane potential is used to study the spatiotemporal dynamics of arrhythmias. NADH imaging provides insight into mitochondrial metabolic fluctuations and high-speed optical spectroscopy quantifies intracellular alterations of myoglobin oxygenation and mitochondrial redox state. The lab's research provides deeper insight into the development of new clinical devices and pharmaceutical therapies to prevent sudden cardiac death and to reduce the debilitating impact of sleep apnea and heart failure.

The Medical Image Analysis Laboratory, directed by Professor Murray Loew, conducts research into methods to enhance, display, combine, and extract diagnostic information from medical images and signals. We develop techniques in one to four dimensions for high-accuracy image registration, tissue characterization, and disease detection using both conventional (MRI, CT, PET, ultrasound) and emerging (optical coherence tomography, infrared, impedance) imaging modalities. Much of the research is conducted in collaboration with clinicians to ensure that the results have clinical value.

Biofluid Dynamics Lab
The Biofluid Dynamics Lab (BDL) is directed by Professor Michael Plesniak. Research in the BDL focuses on experimental in vitro investigations of unsteady, viscous physiological flows. Most processes within the body involve laminar, or non-turbulent fluid flow, but aeroacoustics of speech and pathological blood flow through arteries are rare exceptions that offer a wealth of challenging fluid dynamics issues. Current research includes the study of secondary flows caused by curvatuire in the vasculature and their interaction with arterial stents, and the biophysics of human speech production, including the effects of pathologies such as polyps.

Laboratory for Computational Physics and Fluid Mechanics
This lab aims to develop high-fidelity modeling tools applicable to multiphysics/multiscsale flow problems in physical and biological systems. Central to its work is the synergy of mathematical modeling and computational algorithms coupled to the remarkable advancements in computer hardware technology, which enable us to simulate a wide variety of natural phenomena. The current thrusts are fluid-structure interactions, multiphase turbulent flows, and multiscale modeling of the blood circulation and related biomedical devices. An example problem in the latter category is the two-way interaction between the macroscopic flow patterns and blood elements, which represents the link between fluid mechanics and clinical applications. These computations involve the interactions of fluid flow with millions of deformable particles, which are only possible on the latest petascale supercomputing platforms.
