- Description:
- This dissertation provides evidence that reading is best explained as rational gathering of visual information to identify words efficiently. Although empirical evidence from human reading research suggests a close link between eye movements and cognitive process, it is not clear how readers decide when and where to move their eyes...

- Description:
- Since their discovery, polymeric and protein-based materials are key to technological innovation and are indispensable in our lives. However, these natural and man-made soft materials usually have complex and hierarchical structures, with basic functional units in submicron scale. Therefore, a major challenge in understanding and designing these materials lies...

- Description:
- Economic development is a complex and multi-faceted process. Among its many causes, two are particularly consequential: government and technology. By shaping the landscape of economic incentives, they impact how agents interact, invest, and innovate, which in turn affects the creation of wealth. In this dissertation I explore how this interaction...
