Free space optical communication (FSO) offers a promising solution to the “last mile” bottleneck of high-speed telecommunications. Data is encoded using a modulated laser and optically sent through the air to a receiving photodetector. Although this requires FSO systems to have direct line-of-sight between the emitter and receiver, this is...
Bacterial microcompartments (BMCs) are proteinaceous organelles contained within prokaryotes used to facilitate reactions with increased efficiency, or to carry out reactions with intermediates that are harmful to the cell if released into the cytoplasm. Oftentimes, compartments are used to metabolize unique carbon sources, such as 1,2-propanediol (1,2-PD), whose metabolic pathway...
The basal layer of human epidermis is composed of progenitor cells that both self-renew and differentiate to form stratified epidermal tissue; this process requires strict, dynamic regulation of gene expression. The Super Elongation Complex (SEC) regulates gene expression at the level of transcription elongation by releasing RNA Polymerase II from...
In the past few years, educators have been pushing for an integration of the arts into science, technology, engineering, and math (STEM) learning in order to promote innovation and creativity in these fields. The present study explores the relation between creativity and STEM learning among young children in digital and...
This dissertation explores topics in information economics. A particular focus in this dissertation is how competition affects incentives for information acquisition and information sharing between competitors. The first chapter studies a principal-agent setting where two principals compete for the services of one agent. The second chapter studies how competition in...
Advances in biosensor engineering have enabled the design of programmable molecular systems to detect a range of pathogens, nucleic acids, and chemicals. Here, we engineer and field-test a biosensor for fluoride, a major groundwater contaminant of global concern. The sensor consists of a cell-free system containing a DNA template that...
Hyperpolarization-activated cyclic nucleotide-gated (HCN) channels are expressed in the heart and central nervous system where they regulate membrane excitability. Recently, inhibiting HCN channels in the hippocampus has been identified as a possible therapeutic intervention for the treatment of Major Depressive Disorder (MDD). However, based on the high expression level of...
