- Description:
- Atrial fibrillation (AF) is the most common cardiac arrhythmia, and associated with increased risk for ischemic stroke and mortality. While the risk of stroke has been shown to be reduced with the use of oral anticoagulants like Warfarin, these medications are predictably linked with an increased risk of bleeding, and...

- Description:
- I present the body of work I have pursued over the course of my doctoral study at Northwestern University. First, I conduct an analysis of the measurement abilities of distinctive LISA detector designs, examining the influence of LISA's low-frequency performance on the detection and characterization of massive black hole binaries....

- Description:
- Automobile transportation is among the leading sources of greenhouse gas emissions in the United States, and reducing vehicle miles traveled must be part of our climate change mitigation efforts. One recent trend that, if accelerated, could aid in this effort is the increase in bicycling for transportation in large US...

- Description:
- Voltage-gated Na channels are expressed in all neurons, and are responsible for the upstroke of the action potential. They are part of a complex of proteins that includes pore-forming α subunits and auxiliary subunits that modify their trafficking, gating, and function. The modulation of Na channels by auxiliary subunits is...

- Description:
- The complex structure of typical heterogeneous catalysts, where nanoparticles of active material are dispersed onto the surface of a thermally stable support with a high surface area, complicates the understanding of how the support can affect the resulting catalyst structure and properties. Using well-faceted and shape-controlled oxides as supports would...

- Description:
- The effective capture and detoxification of chemical warfare agents (CWAs) is a pressing need in the modern world. Materials are needed for both the destruction of weapon stockpiles and personal protection via fabric coatings or respirators. Attractive candidates for these applications include metal–organic frameworks (MOFs) – highly crystalline materials composed...
