It is still surprisingly challenging to clearly capture many important biological events. The image resolution, field-of-view, and video frame rate of many optical recordings are still not as high as they should be. In addition, scattering prevents us from seeing beneath the very top layers of biological tissue. These limits are felt across many areas of study, from the pathologist who can only examine one small part of a histology slide at a time, to the neuroscientist who can only use light to monitor neural activity along the top surface of the brain.
The Computational Optics Lab develops new optical tools and algorithms to overcome these barriers. Here are a few current projects:
1. A microscope to capture gigavoxel-scale 3D images using principles from Fourier ptychography
2. Techniques to optically record in vivo neural activity in freely moving organisms
3. Enabling high-speed detection of blood flow and motion deep within tissue using principles from machine learning
Interested in joining the lab? We are currently seeking PhD and post-doctoral candidates! Please feel free to get in touch with me if you are interested in working with optics, with machine learning, or ideally with both. I am especially interested in those who know their way around an optics table!
