"Weak-lensing measurements demystified"
I will explain what weak lensing is good for and how the measurements are actually done, review the current state of affairs and lay out why it is not sufficient for even the near future. I'll conclude with a possible solution.

"Detection of GZK Neutrinos with Radio Detectors"
The Greisen-Zatsepin-Kuzmin (GZK) hypothesis proposes that the the highest energy cosmic rays interact with the cosmic microwave background, creating a suppression of the flux of these ultrahigh energy particles. In the interaction, ultrahigh energy neutrinos would also be created, which would not be subject to the subsequent series of interactions over its propagation distance. There are several detectors being built which propose to detect these neutrinos through radio signals produced via the Askaryan effect. Their detection will help to confirm the GZK hypothesis as a mechanism of cosmic ray flux suppression. I will outline my current and future work in developing a couple of these new projects: the Askaryan Radio Array (ARA) and the ExaVolt Antenna (EVA). For ARA, I have been concentrating on merging simulation and reconstruction. For EVA, I have been working a simulation of the antenna for planning and design purposes.
