- Description:
- This thesis consists of three papers studying applied microeconomics and economic history. The chapters are broadly organized around two different topics: the political effects of media and the consequences of disruption to human capital. In the first chapter, joint with Susan Ou, we study the role of media in the...

- Description:
- Many industrial fluid flow problems involve the interaction between heavy, rigid objects and one or more fluid phases. For several decades, there has been a vested interest in simulating these fluid-structure interaction (FSI) problems in order to improve engineering design processes. However, numerical simulations of these problems can be challenging...

However, microfluidic technologies have largely been applied to gamete-level culture in reproductive biology, with very little progress in organ-level culture. Herein...

- Description:
- Pathogenic bacteria scavenge essential nutrients including metals, amino acids and peptides to survive within the hostile host environment. Bacteria utilize ATP-binding cassette (ABC) transporters, powered by the energy of ATP hydrolysis, to move substrates across cellular membranes. The substrate-binding protein (SBP) shuttles substrate in the periplasm and directs the substrate...

- Oocyte meiosis is a specialized, but error prone, form of cell division that is poorly understood. Errors during meiosis often result in aneuploidy, or abnormal chromosome number, that impacts human health and fertility. Aneuploidy is the leading cause of miscarriages and birth defects, such as Down's syndrome in which cells...
