Passive methane oxidation biosystems design and instrumentation

Landfill emissions can continue for decades after biogas extraction systems have been turned off. The possibility of land reclamation projects, such as turning an old landfill into a park, depends of passive, low-maintenance, technologies that can cope with these emissions. The main goal of this research is to design, construct and monitor a pilot-scale passive […]

Quantifying the value of community science data for conservation

Community science, the public participation and collaboration in monitoring and research, is rapidly emerging as an effective means to collect vast quantities of data in a cost-efficient manner. This may prove invaluable to conservation efforts, as using crowd-sourced data to inform decisions can allow managers to redirect limited funds towards action rather than monitoring. My […]

Minimizing the Impacts and Maximizing the Benefits of Marine Shipping Activities for Arctic Communities Through the Use of Traditional Knowledge

Interest in Arctic shipping is growing as sea ice is melting and as other industries are developing. An increase in shipping presents risks to both the natural environment (from the movement of ships and the products that they carry) and to the local communities that rely on those healthy environments for food and other products. […]

Earth X-ray for Low-Impact Mining

Meeting our national and global commitments to emission reductions requires the increasing utilization of clean technologies. The demand for the minerals needed in clean-tech (such as nickel, copper, zinc, and cobalt) is expected to grow by at least fivefold in the coming years. At the same time, the mineral resource industry needs to reduce its […]

Aeration of hydraulic turbines for increased dissolved oxygen

In warm climates warm temperatures cause thermal stratification in hydropower reservoirs inhibiting mixing and leading to deoxygenation of waters at depth (hypolimnium). Turbines withdrawing water at depth result in low dissolved oxygen (DO) in the downstream flow having a large negative impact on the downstream riverine ecosystem. Legislation in the USA and elsewhere now requires […]

Application of a DNN model for seismic performance prediction of structures retrofitted with steel dampers

The intensity and frequency of earthquakes in Korea have increased in the past few years. Thus, the need for seismic retrofit of many middle- or low-rise buildings has increased which were designed without seismic design provisions. Nonlinear time history analyses need to be performed for accurate seismic performance evaluation and for appropriate retrofit of structures. […]

Rapid evolution of threespine stickleback

I will examine the limits of evolution by investigating morphological and genetic variation of threespine stickleback populations in real time, under the supervision of Dr. Eric Palkovacs at the University of California, Santa Cruz. According to evolutionary theory, organisms experience selective pressures, which can result in adaptation and evolution. Since strong selection events are frequently […]
