GRADUATE STUDENTS

toby_maxwell.jpgToby Maxwell, PhD Candidate

Agricultural and Environmental Chemistry

tmaxwel@ucdavis.edu

Research Interests: Nutrient cycling in agricultural and natural ecosystems, stable isotopes as indicators of biophysical processes, plant-soil-water interactions as a way of understanding environmental interactions at local and ecosystem scales.

Hobbies: backpacking, skiing, music.

Horticulture and Agronomy

robfranco@ucdavis.edu

Research Interests: The main objective of my thesis research is to investigate and mitigate NOx and N2O formation and emissions from silage. This research will potentially reduce the local air pollution due to NOx emissions and reduce the emission of N2O, the most potent greenhouse gas, which has 310 times more global warming potential than carbon dioxide. I also would like to consequently increase the nitrogen use efficiency (NUE) of the forage crops utilized for silage making. This research would benefit the dairy and beef cattle farmers by developing ensilage techniques to help prevent nitrogen losses to the environment and promote more effective application of nitrogen fertilizer to the forage crops.

Hobbies: I love swimming in lakes and rivers, I like to hike or walk with my dog in nice places and views, I like riding horses a lot, I am an animal fan (I would have all of them if I had the money and space), I love traveling to new places.

Soils and Biogeochemistry

hwaterhouse@ucdavis.edu

Research Interests: Broadly, I am interested in the intersection of agriculture management and environmental quality. My main focus is on nutrient cycling - in particular nitrogen - and the transport and fate of reactive nitrogen from agricultural systems into the environment. I am interested in mitigating the impact human dominated ecosystems have on the natural environment. My work has included research in identifying agricultural management practices to reduce N2O emissions, remediating salt affected soils on subsistence farms in Bangladesh, and modeling the transport of NO3- to groundwater in agricultural systems in the central valley. 

Hobbies: cooking, traveling, backpacking, biking, brewing

Soils and Biogeochemistry

bbomfim@hotmail.com

Research Interests: In my PhD project I will examine how disturbance affects nitrogen and phosphorus dynamics and how these influence Amazon forest ecosystems as a result of interactions between resource availability in soils and shifting demands from vegetation at different successional stages following fire and logging disturbance.

International Agricultural Development

rbyrnes@ucdavis.edu

Research Interests: I am interested in understanding soil processes from from mechanistic and applied perspectives with the end goal to provide managers and policy makers with data which can help protect the environment and enhance livelihoods. Currently, I am conducting experiments to assess the role of sub-surface drip irrigation as a nitrous oxide emissions mitigation tool. I also plan to conduct an experiment to evaluate the efficacy of nitrification inhibitors across a variety of soil textures, as well, I am developing and experiment to assess the role of available carbon in low-oxygen soil environments in determining dominant nitrous oxide production pathways. Before coming to graduate school I worked abroad in Africa with farmers to develop soil and water management strategies in smallholder farming systems. I am continuing to pursue avenues for outreach and research abroad and have been awarded a USAID Fellowship to conduct an experiment that will examine different biological nitrification inhabitation strategies in tropical pasture systems.

Hobbies: When I’m not working or studying I love spending time outdoors; climbing, surfing and playing soccer. I also enjoy cooking good food, drinking good beer and wine and spending time with friends.
