Using machine learning methods to aid scientists in laboratory environments
As machine learning gains popularity as a scientific instrument, we look to create methods to implement it as a laboratory tool for researchers. In the first of two projects, we discuss creating a real-time interference monitor for use at a radio observatory. We show how deep neural networks can be …

STED microscopy in the visible range
Light microscopy is a key scientific instrument in the life sciences. However, the resolution of far-field light microscopy is limited by diffraction. Exploiting a saturated depletion of the molecular excited state by stimulated emission, stimulated emission depletion (STED) breaks the resolution …
