This dissertation explores hip-hop as a moral philosophy in action; a set of aesthetic and ethical values that manifest in young people’s perspective about the good life. Hip-hop is an arts movement of rap, movement, and style originating among Black and Latinx youth in the South Bronx during the late...
Numerous photophysical processes in both natural and artificial systems are dictated by the interaction between chromophores. For example, in photosynthesis, light is absorbed by an antenna complex composed of an array of chlorophyll chromophores that collectively transfer the energy to the reaction center where interactions between a series of redox...
Social comparison is a ubiquitous part of social life. People compare themselves to others to establish and maintain a sense of social hierarchy and structure, to develop and sustain interpersonal relationships, and even to help understand themselves. In this dissertation, I focus on how the referent of social comparison –...
The critical importance of alternative mRNA splicing and the RNA binding proteins that orchestrate this essential layer of post-transcriptional gene regulation is increasingly recognized in gene regulatory programs. We and others have shown that alternative splicing plays a causal role during the Epithelial-Mesenchymal transition, a cell-developmental program that is hijacked...
Viral Verses investigates the influence of social media publication on the relationship between poetry and community formation in southeastern Africa. As more artists in the global South reach wider audiences through online publication, poetic form has shifted to reflect social media’s aesthetic norms, embracing urgency, contemporaneity, and populism. Digital media...
Increasing industrialization and the resulting negative environmental impacts highlight the need to develop alternative renewable energy sources. The Sun is a massive source and organic solar cells are a growing field of study. As new materials are synthesized, the efficiencies of organic solar cells continue to grow, but without an...
Surface-enhanced Raman spectroscopy (SERS) is a powerful analytical technique that can detect single molecules and simultaneously obtain structural information. When an analyte molecule binds to a nanostructured noble metal surface, the otherwise weak normal Raman signal is enhanced by as much as a factor of 108. This makes SERS the...
This work combines the use of high-throughput mass spectrometry with peptide arrays for to monitor reactions on peptides. The Mrksich lab introduced a high-throughput, label-free, biochemical assay that relies on self-assembled monolayers on gold and matrix-assisted laser desorption/ionization mass spectrometry, termed SAMDI-MS. This dissertation introduces new applications of SAMDI-MS and...
Organismal development depends upon countless cell decisions to adopt particular fates at the appropriate time and place. These decisions are executed by systems of biochemical reactions called regulatory networks. Elucidating the general principles underlying the structure and function of these networks is vital to understanding all developmental processes, as well...
This study examines how Latino migration politics developed in Chicago from the 1930s to the 1970s. Although scholars usually identify the emergence of Latino immigration activism in the 1960s and predominantly in the region of the Southwest with the farm workers movement, this study argues that immigration activism began much...
