This will be a talk mostly on wave dark matter - if the dark matter constituent is lighter than about 10 eV, dark matter is best thought of as a set of waves. After a brief introduction, we will discuss two recent ideas that explore the implied wave...

Recent cosmological data hint at a neutrino mass sum below the minimum value physically allowed by neutrino oscillations, with a preference for the opposite of massive neutrinos. Within ΛCDM, Planck CMB, ACT+Planck+SPT CMB lensing and DESI DR2 BAO...

Dark matter is one of the central open problems in fundamental physics. Many well-motivated candidates interact with the Standard Model through portals beyond gravity, yet to date the most robust evidence for dark matter remains purely gravitational...

I will discuss a recent proof-of-concept waveform model (arxiv.org/abs/2511.10522) that augments post-Newtonian quations using ideas from physics-informed neural networks and universal differential equations. I will then discuss ongoing efforts to...

Planets are built from small dust grains embedded in gaseous protoplanetary disks. As such, the associated gas dynamics and dust-gas interactions play key roles in modern theories of planet formation and evolution. In particular, several...
