- Description:
- Although flowing granular materials have been formally studied for over two hundred years, their behavior is still poorly understood relative to fluids, solids, and gases. Sheared granular materials with differing particle properties (e.g., size, density, shape) segregate (de-mix) due to percolation (small particles fall between large ones) and buoyancy (light...

- Description:
- Respiratory-swallow coordination is implicated as an essential component of safe and efficient swallowing, yet current evidence is incomplete regarding its relevance to swallowing impairment, assessment and treatment. Three studies were conducted that: 1) characterized and confirmed the optimal respiratory-swallowing coordination patterns in healthy adults, 2) identified linkages between deviations in...

- Description:
- This dissertation is on daily policing dynamics in China, centering around one core question: why coercive institutions can be extremely efficient for some issues but nearly dysfunctional for others in authoritarian regimes. The police may enforce the law relentlessly in some cases, even if there is no clear harm, but...

- Description:
- Carbon nanotubes (CNTs) have exceptional properties and are mass-producible at the ton scale as aggregated powders, but their difficulty in processing is a significant barrier to widespread use. Even after decades of research, there still isn’t a solvent for CNTs that is massively available, easily removable, and non-damaging. The need...

- Description:
- This thesis contains three chapters studying macroeconomics and trade. The chapters are organized into two topics: inflation expectations and perceptions, and the effect of trade intermediation on economic activity. In the first chapter, I investigate whether households are significantly harmed by inaccurate beliefs about inflation. The chapter analyzes two established...
