The carbapenem antibiotic meropenem was initially approved by the FDA in 1995 with the dosing regimen of 1 g to be administered every 8 hours. Subsequent studies involving mathematical modeling of pharmacokinetic behavior of this antibiotic proposed a smaller effective dose of 500 mg given every 6 hours, resulting in a lower total daily dose by 1 g. Three previous clinical studies evaluating th...

My current and planned research divides into three areas: the relationship between stable and unstable cohomology operations, the differential topology of loop spaces, and the use of category theory in geometry. This research lies in the areas of algebraic topology, differential topology, and differential geometry and it has further application to mathematical physics. In addition to the techni...

Video rewrite is a new field of research aiming to utilize the photo-realism of real video input to synthesize new video output without having three dimensional (3D) information of the scene. It can be categorized under the emerging field of image-based rendering (IBR) or more specifically videobased rendering. The main advantage of video rewrite is the realism it offers because it directly use...

Privacy and anonymity are essential to society in both the physical and the electronic domain. Anonymous police tips and witness protection programs are common in the physical realm. The Internet can provide an electronic medium for free expression, but not if users can be identified and censored by totalitarian governments. There have been many attempts to provide anonymous electronic communic...

Actors are intelligent pieces of software automously performing some function within a larger system. The current state of the art generally allows for either an actor to have complete control over the performance of the task or for a user to take back complete control. This work will look at intermediate levels of control, i.e. users having partial control over the performance of a task. Speci...

Introduction: The California Coastal Sediment Management Workgroup (CSMW) has requested proposals from the U.S. Geological Survey (USGS) Western Coastal and Marine Geology Team (WCMG) to evaluate the transport and fate of fine sediments discharged into California coastal waters. The rationale for this proposed work is a need to better understand the environmental consequences of beach nourishme...

Teenagers are using the internet for a variety of social and identity-based activities, but in doing so, they are exposed to risky situations. The work of ensuring teens’ online safety largely falls to parents, many of whom are unprepared to understand the realities and norms of teens’ online activity. In this thesis, we will investigate how parents and teens perceive online risks, the efficacy...

AI has long been applied to the problem of predicting nancial markets. Recently, developments in both AI and nancial economics have opened up the possibility for close collaboration between the two elds. First, a line of economics research has emerged that uses AI market forecasting as a form of applied econometrics. Just as importantly, an entirely new source of nancially relevant data has bec...
