Abstract: This tutorial will introduce computational imaging as a broad range of techniques in which algorithms play a major role in the final image formation process. The basic recipe for computational imaging involves coming up with a forward model that can simulate/predict what your imaging system measures. This model is computationally inverted to reconstruct the object under investigation.

The Exploring Social Identities workshop is an hour long workshop designed for participants to recognize their own intersecting identities and those of others, while learning to be empathetic and open-minded to the experiences of others. This workshop will include in-depth conversations as well as tasty snacks. Hope to see you all there!

Abstract: Black holes provide a window into quantum gravity through their thermodynamic properties. Recently, it has been discovered that higher topology solutions provide additional information about the UV and play an essential role in its consistency. I will discuss how these solutions are used to study statistical properties of the quantum theory, and describe the example of thin-shell wormholes, which are used to understand the coarse-grained entropy of black holes formed by gravitational collapse.
Abstract: I will discuss recent insights into the physics of particle acceleration based on spacecraft observations of shocks associated with fast coronal mass ejections (CMEs). The acceleration of charged particles to high energies is a fundamental topic in plasma astrophysics. High energy particles themselves are useful probes of processes occurring far from Earth, either near the solar atmosphere, in the outer heliosphere, or in distant astrophysical sources, such as supernovae blasts.

Synopsis: Andreotti has worked to understand hematopoietic cell signaling to understand cell signaling pathways such as T cell receptors by working on substrate binding and catalytic activity of families of protein tyrosine kinases ( IL2-inducible tyrosine kinase (Itk)). The lab uses NMR spectroscopy to determine 3D structures of various protein domains and examine interactions between domains.

Abstract: To date, neutral atom optical lattice clocks have demonstrated the highest precision measurements of fractional frequency shifts. State-of-the-art optical oscillators employing cryogenic reference cavities have been used to push this frontier, enabling record-level stabilities and resulting in foundational advances in optical frequency metrology. The fundamental performance of cryogenic cavities utilizing crystalline spacers and substrates has been limited by the Brownian thermal noise associated with mechanical dissipation of the mirror coatings.
Abstract: Radial diffusion is a key transport process that takes place in the radiation belts. In addition to re-distributing radiation belt particles, inward radial diffusion energizes particles and outward radial diffusion can contribute to loss of particles across the magnetopause.
