- Description:
- Persons with spinal cord injuries can use state-of-the-art brain-computer interfaces to control robotic arms. Despite this high-tech solution, their movements are slow and imprecise, much like those made by individuals who have lost proprioception, the sense of body position and movement. Intracortical microstimulation (ICMS) used to reactivate neural circuits in...

- Description:
- Organic photovoltaics offer an opportunity to make solar cells more affordable and widely accessible using cheap, solution-processable light-absorbing layers. In order to realize new technologies, a fundamental understanding of organic chromophore photophysics is required to overcome efficiency limitations. Throughout this doctoral work, I investigated the kinetic and physical characteristics of...

- Description:
- Sea urchins are virtuosi of biomineralization, the process by which organisms build mineralized tissues. The embryonic animal exemplifies this with the formation of its endoskeletal spicule. The primary mesenchyme cells (PMCs) undertake spicule synthesis, which involves deposition of the initial granule, elongation of the spicule, and several choreographed changes...

- Description:
- The answer to the question “Why do we sleep?” lies in understanding the biological underpinnings of homeostatic drive to sleep. Wakefulness is correlated with numerous changes in brain activity, structure and gene/protein expression that re-normalize following sleep however which of these elements is sufficient to cause sleep drive and how...

- Description:
- Rising social inequality across economic, gender, and racial lines is a pressing issue of our time. Despite widespread agreement that inequality exists, there are stark ideological disagreements about its extent, its victims, and about what – if anything – should be done to address it. Prior work demonstrates that the...
