Multistable structures - from deployable structures to robots
Multistable structures can reversibly change between multiple stable configurations when a sufficient energetic input is provided. While originally the field focused on understanding what governs the snapping, more recently it has been shown that these systems also provide a powerful platform to design a wide range of smart structures.
In this talk, I will first show that pressure-deployable origami structures characterized by two stable configurations provide opportunities for a new generation of large-scale inflatable structures that lock in place after deployment and provide a robust enclosure through their rigid faces. Then, I will demonstrate that the propagation of transition waves in a bistable one-dimensional linkage can be exploited as a robust mechanism to realize structures that can be quickly deployed. Finally, while in the first two examples multistability is harnessed to realize deployable architectures, I will
demonstrate that bistable building blocks can also be exploited to design crawling and jumping robots. Unlike previously proposed robots that require complex input control of multiple actuators, a simple, slow input signal suffices to make our system move, as all features required for locomotion are
embedded into the architecture of the building blocks.

Testing General Relativity with Black Hole Mergers
Testing the predictions of general relativity in the dynamical
strong-field regime, in particular black holes and their dynamics,
has only recently become possible with LIGO/Virgo observations of
black hole mergers. I will review some of the tests that have
been performed to date. However, one obstacle to extracting the
most stringent constraints possible is the lack of predictions of
what black hole coalescence should "sound" like in modified gravity
theories (or theories that offer exotic alternatives to black holes).
To make things worse, there are doubts as to how well-posed many
modified gravity theories are that have been claimed would give observably
different merger waveforms. One such theory is Einstein-dilaton-Gauss-Bonnet
(EdGB) gravity. I will describe results trying to address the well-posedness
of EdGB gravity in the non-linear regime. Restricting to gravitational
collapse in spherical symmetry, we find that there is an uncomfortably
small region of parameter space in the strong-field regime where EdGB gravity
can still make sense as a classical extension to general relativity.

Soft Matter Science and the COVID-19 Pandemic
Much of the science underpinning the global response to the COVID-19 pandemic lies in the soft matter domain. Coronaviruses are composite particles with a core of nucleic acids complexed to proteins surrounded by a protein-studded lipid bilayer shell. A dominant route for transmission is via air-borne aerosols and droplets. Viral interaction with polymeric body fluids, particularly mucus, and cell membranes controls their infectivity, while their interaction with skin and artificial surfaces underpins cleaning and disinfection and the efficacy of masks and other personal protective equipment. The global response to COVID-19 has highlighted gaps in the soft matter knowledge base. I will survey these gaps, especially as pertaining to the transmission of the disease, and suggest questions that can (and need to) be tackled, both in response to COVID-19 and to better prepare for future viral pandemics.
