Bio Optical & Acoustic Spectroscopy Lab

Welcome to the Bio Optical and Acoustic Spectroscopy Lab!

April 2023

 Our lab develops novel optical methods and applies them principally to study the brain. We have recently expanded to complement our suite of technologies with high speed functional ultrasound and are considering integration with photo-acoustics. Our technologies are used for measuring brain function and physiology on microscopic to macroscopic length scales and are applied in species ranging from mice to human. Our applications have been focused on measuring hemodynamic responses to brain activity in humans and rodents, neuro-metabolic-vascular coupling, oxygen delivery through the cerebral microvascular network, tissue oxygen metabolism, and the impact of disease and injury including stroke, Alzheimer’s disease, and aging.

We work closely with the BU Neurophotonics Center in the development and dissemination of our neurophotonic technologies to ensure broad adoption and impact. We support a large community of fNIRS users through our data analysis software package Homer, training workshops, and a soon to launch NIH R24 fNIRS Ecosystem for Open Software-Hardware Dissemination”. Please visit the BU Neurophotonics Center website to learn more about the resources available through the Center.
