Essays on corporate governance and investor disagreement
(Massachusetts Institute of Technology, 2013)
This thesis consists of two essays examining the roles of corporate governance and investor disagreement, respectively, in the performance and stock market valuations of firms. In the first chapter, I demonstrate that the ...
Stiffness characterization of mechanically-compressed cohesive soils using wave propagation
(Massachusetts Institute of Technology, 2016)
Wave propagation through soils is a non-destructive method used to characterize soil stiffness properties and is the basis for geophysical interpretations. Due to the difficulty of measuring shear waves through soft cohesive ...
Natural and synthetic estrogens in wastewater treatment plant effuent and the coastal ocean
(Massachusetts Institute of Technology, 2013)
Steroidal estrogens are potent endocrine disrupting chemicals that are naturally excreted by vertebrates (e.g., humans and fish) and can enter natural waters through the discharge of treated and raw sewage. Because estrogens ...
Risk implications of the deployment of renewables for investments in electricity generation
(Massachusetts Institute of Technology, 2014)
This thesis explores the potential risk implications that a large penetration of intermittent renewable electricity generation -such as wind and solar power- may have on the future electricity generation technology mix, ...
Statistical learning for decision making : interpretability, uncertainty, and inference
(Massachusetts Institute of Technology, 2015)
Data and predictive modeling are an increasingly important part of decision making. Here we present advances in several areas of statistical learning that are important for gaining insight from large amounts of data, and ...
Phenotypic heterogeneity and evolutionary games in microbial populations
(Massachusetts Institute of Technology, 2015)
One of the most interesting discoveries of the last decade is the surprising degree of phenotypic variability between individual cells in clonal microbial populations, even in identical environments. While some variation ...
Architectures for photon-mediated quantum information processing
(Massachusetts Institute of Technology, 2018)
In this thesis, I present architectures for quantum information processing where photons are used as the quantum bit (qubit) or for mediating entanglement between other qubits. The emphasis of this research is to simplify ...
Iterative methods, combinatorial optimization, and linear programming beyond the universal barrier
(Massachusetts Institute of Technology, 2015)
In this thesis we consider fundamental problems in continuous and combinatorial optimization that occur pervasively in practice and show how to improve upon the best known theoretical running times for solving these problems ...
Youth and cities : planning with low-income youth and urban youth cultures in New York City and Paris
(Massachusetts Institute of Technology, 2014)
Are the cities of North America and Europe governed, built, and planned by authorities to encourage youth development or facilitate repression? Youth and Cities: Planning with Low- Income Youth and Urban Youth Cultures in ...
A magmatic trigger for the Paleocene-Eocene thermal maximum?
(Massachusetts Institute of Technology, 2015)
Fifty-six million years ago Earth experienced rapid global warming (~6°C) that was caused by the release of large amounts of carbon into the ocean-atmosphere system. This Paleocene-Eocene Thermal Maximum (PETM) is often ...
