Algorithms for Allocation Problems in Online Settings
(2018)A fundamental computational challenge that arises in the operation of online systems, services, and platforms is that of resource allocation. Broadly defined, a resource allocation problem is one where set of users generaate ... -
Advances in Bayesian Modeling of Protein Structure Evolution
(2018)This thesis contributes to a statistical modeling framework for protein sequence and structure evolution. An existing Bayesian model for protein structure evolution is extended in two unique ways. Each of these model exttensions ... -
Metal-Ligand Interactions in Stimuli Responsive Molecules
(2018)The ability to control changes in physical and chemical properties has allowed stimuli responsive molecules to be used in a variety of applications. Incorporating metals into stimuli responsive molecules introduces propeerties ... -
Essays on Propensity Score Methods for Causal Inference in Observational Studies
(2018)In this dissertation, I present three essays from three different research projects and they involve different usages of propensity scores in drawing causal inferences in observational studies. Chapter 1 talks about the ... -

Genetically Encoded Albumin Binding Drug Delivery Systems
(2018)Albumin is emerging as a promising and versatile carrier to improve the pharmacokinetic and therapeutic profiles of drugs because of its unique physiological properties. The objective of this dissertation is to develop ddrug ... -
Finite Sample Bounds and Path Selection for Sequential Monte Carlo
(2018)Sequential Monte Carlo (SMC) samplers have received attention as an alternative to Markov chain Monte Carlo for Bayesian inference problems due to their strong empirical performance on difficult multimodal problems, natuural ... -
Fluid Flow and Electromagnetic Fields Modeling for Geophysical Subsurface Sensing
(2018)Crosswell electromagnetic (EM) fields measurement has been widely applied in oil industry which has a reservoir scale detection range. One of the limitation of this technique is that the EM singals are usually too weak tto ... -
Leveraging Bioorthogonal Chemistry for Hyperpolarized Magnetic Resonance and Metal Uncaging
(2018)Bioorthogonal chemistry is a burgeoning area of study that has innumerable applications. This dissertation describes applications of bioorthogonal chemistry to solve problems in the fields of imaging and metal uncaging. ... -
Comparing Self-Monitoring Strategies for Weight Loss: Does Developing Mastery Before Diet Tracking Enhance Engagement?
(2018)Self-monitoring of dietary intake is a valuable component of behavioral weight loss treatment but engagement in self-monitoring declines quickly, resulting in suboptimal treatment outcomes. This dissertation examined a nnovel ... -
The Weight of Hope: Independent Music Production Under Authoritarianism in Egypt
(2018)This dissertation is an ethnographic study of the independent music scene in Cairo, in which music producers and cultural entrepreneurs who came of age during the 2011 revolution and 2013 counterrevolution hope to constiitute ... -
