Multiphoton microscopy can resolve fluorescent structures and dynamics deep in scattering
tissue and has transformed neural imaging, but applying this technique in vivo can be limited …

Multiphoton microscopy has emerged as the primary imaging tool for studying the structural
and functional dynamics of neural circuits in brain tissue, which is highly scattering to light. …

We report a method for the phase reconstruction of an ultrashort laser pulse based on the
deep learning of the nonlinear spectral changes induce by self-phase modulation. The neural …

The thin-film post-compression technique has the ability to reduce the pulse duration in PW-class
lasers, increasing the peak power. Here, the nonlinear response of an increasingly …

Significance: Three-photon excitation microscopy has double-to-triple the penetration depth
in biological tissue over two-photon imaging and thus has the potential to revolutionize the …

Background Perception and behavior require coordinated activity of thousands of neurons
operating in networks that span millimeters of brain area. In vivo calcium imaging approaches …

Though wakefield acceleration in crystal channels has been previously proposed, x-ray
wakefield acceleration has only recently become a realistic possibility since the invention of the …

The advent of the path to a single cycle X-ray laser pulse via thin film compression and the
relativistic compression enables laser wakefield acceleration in solid materials. We study the …

… I have been very fortunate to have many members of the Farinella and Haag families who
have been very supportive and inquisitive about my studies and have inspired me to be the …

Here we investigate the wakefield acceleration induced by a coherent, ultrashort X-ray
pulse guided by a nano-scale channel inside a solid material via particle-in-cell simulations. …
