Annual Diversity Seminar Website Event: "Cultivating Equity-Focused Institutional Change in University STEM Departments"
Gina Quan (San José State University)
Discipline-based education research has made great strides in understanding how to foster more equitable and effective teaching in science, technology, engineering, and mathematics (STEM). However, there still has…
Astronomy Seminar: The First Flight of SPIDER: A view to the dawn of time from above the clouds
Jeffrey Filippini (University of Illinois)
Inflation is thought to have seeded the cosmos with a hum of primordial gravitational waves - unique messengers from the universe's earliest moments. If present, these should have left a unique "B-…

High Energy Theory Seminar: Illuminating the Early Universe with Dark Matter Minihalos
Adrienne Erickcek (UNC)
As remnants of the earliest stages of structure formation, the smallest dark matter halos provide a unique probe of the evolution of the Universe prior to the onset of Big Bang nucleosynthesis (BBN…
Physics and Astronomy Colloquium: "Non-thermal pathways to quantum matter "
Martin Claassen (University of Pennsylvania)
Quantum materials host a wide range of phenomena that challenge our physical understanding while offering intriguing possibilities for next-generation technologies. A promising direction towards…
Mathematical Biology seminar: "Spinning helices, heaving panels, and waving tails: the role of flexibility in propulsion"
Lisa Fauci (Tulane University)
The observed gait of a swimmer arises from the interplay of internal force generation, the passive elastic properties of its body, and environmental features such as fluid viscosity,…
High Energy Theory Seminar: Entanglement entropies of equilibrated pure states and the origin of replica wormholes
Shreya Vardhan (MIT)
I will explain an approximation method that gives a simple universal expression for the Renyi entropies of an equilibrated pure state in a chaotic quantum many-body system. This expression is independent…
Astronomy Seminar: Speculating on the origin and future of FRBs
Liam Connor (Caltech)
Fast radio bursts (FRBs) are short-duration transients whose precise origins remain a mystery. A subset of FRBs is known to repeat; a subset of those appears to repeat in periodic activity windows.…
Mathematical Biology seminar: "Some PDEs in Evolution of Dispersal"
Adrian Lam (Ohio State University)
In the first part of the talk, we discuss the multi-species competition in a spatial domain, particularly the result of A. Hastings and some recent progress on the conjecture by Dockery…
High Energy Theory Seminar: Positivity with Gravity
Claudia de Rahm (Imperial College London)
In standard effective field theories, the notion of causality is intrinsically linked with that of subluminality and with a set of positivity constraints to be imposed on the low-energy scattering…
