This dissertation analyzes how suburban school districts made sense of and planned to reduce inequality between 2019–2021. Previous literature has found that suburban schools, despite their reputation as the best in the country, are deeply unequal (Lewis and Diamond 2015; Lewis-McCoy 2014). Building on this previous scholarship, I ask: How...
The hippocampus has been identified as a critical structure for supporting spatial memory processes in both humans and animals alike. Many of these processes such as the ability to self-localize in a given environment as well as engage in goal-directed navigation are thought to depend on the location-specific firing of...
The field of materials discovery is undergoing an unprecedented transition from laboratory tocomputer. Behind this transition is the new ability to accurately compute material properties, especially
energetic stability, from first principles with density functional theory (DFT). However,
DFT remains computationally expensive, and DFT-based materials discovery is intractable, especially
in high...
One method of cancer treatment is to thermally ablate (destroy) tumor masses using heat caused by electric current, or Joule heating. This particular modality is called radiofrequency ablation (RFA), due to the use of electric currents in the 100 kHz to 800 kHz frequency range. Computationally, RFA is simulated as...
This dissertation examines how nineteenth century German literature constructed and experimented with an entangled concept of “the environment” based not in (Romantic) philosophical and literary conceptions of nature, but in the theory and science of color perception. As the visual point of interaction between an observer and their surrounding world,...
As sound changes advance across large geographic areas, they progress unevenly across populations. The speakers who lead these changes often share macro-social identities, like place or social class affiliations (e.g. Nesbitt 2018; Wagner et al. 2016). But the features undergoing these macro-level sound changes also hold social meanings related to...
When attached to another species (e.g. a nanoparticle), the sequence specificity of DNA can be repurposed to program interactions between such entities and to direct their formation into ordered structures. The research presented in this thesis aims to push the boundaries of structures that can be made via this approach....
We consider general utility models and information structures of the agents and illustrate when economic conclusions for designing simple mechanisms in classical settings extends for general environments. We show that whether economic conclusions can be generalized depends on the details of the generalizations. For example, in single-item auction, competition and...
