Christine Tallamy Glazer – Christine Tallamy Glazer is lab manager of the Soil Ecology and Biochemistry lab. She received her MS in Marine Science, with a concentration in Marine Biology/Biochemistry, from the University of Delaware. Upon her arrival on Oahu in 2004, she conducted biogeochemical research utilizing stable isotopes to trace microbial nutrient cycles in recirculating aquaculture systems as a research associate at the Oceanic Institute. After two years at the Oceanic Institute, she taught high school math and science for three years, then returned to the lab as an analyst for the Biogeochemical Stable Isotope Facility at the University of Hawaii. Christine was recently certified as a Community Emergency Response Team member. She enjoys snorkeling, hiking, swimming, and spending time with her husband and two young children.
Jon Wells (Ph.D.) – I am improving the sustainability of bioenergy systems through efficient conversion and carbon economy. My dissertation is titled “UNDERSTANDING CARBON IN LARGE-SCALE AGRICULTURAL PRODUCTION SYSTEMS FOR BIOENERGY IN THE TROPICS: SELECTING SOILS, FEEDSTOCKS, AND CONVERSION PATHWAYS”.
Daniel Richardson (M.S.) – Originally from Oahu, I earned my B.S. through the NREM Department at the University of Hawaii at Manoa. My research interests are soil microbiology, soil health, and the how soils can relate to global sustainability. I enjoy surfing, hiking, and digging holes.
Hannah Hubanks (M.S.) – I grew up in a small town in Wisconsin and proceeded to the University of Wisconsin-Madison, receiving a degree in Zoology with certificates in Environmental Studies and African Studies. For as long as I can remember, I have asked the “why and how” questions about nature’s workings, cuddled any critter that will allow me to do so, and spent as much time as possible in the outdoors, the wilder the better. My love and fascination for nature developed into a career path aimed at preserving it.
I furthered my global understanding of environmental issues and implications by backpacking for nearly two years, and have brought back those diverse perspectives and experiences to life in the United States and here on Oahu where I am now pursing a Master’s degree in Natural Resources and Environmental Management with a focus on soil health and sustainability. My interests in soil health go beyond the laboratory and I aim to make connections with farmers and community members that have a close relationship with the future of soil ecosystem health. When not working, I can typically be found at the beach, in the ocean, or hittin’ the trails.
Casey McGrath (M.S.) – As a New England native, I received my B.S. in Environmental Science with a concentration in Hydrology from the University of New Hampshire. During my time at UNH I worked as a state park ranger naturalist, a storm water specialist for the Department of Transportation and a lab technician in both a university global water quality lab and a U.S. Forest Service water and soil lab. Though being a park ranger and storm water specialist was exciting, I found the greatest excitement and satisfaction through my lab and research experiences. During the end of my time at UNH, I had the wonderful opportunity as an undergraduate to study on the effects of land use change on fish and macroinvertebrate biodiversity in Coromandel Peninsula of New Zealand.
This experience ignited my passion for more land use and climate change driven research. I became interested in getting involved with research projects focused on the way the biosphere interacts with the atmosphere and developing models for predicting the impacts of climate change. Luckily, I am able to participate in this type of research here at the Crow Lab as a M.S. student in Natural Resources and Environmental Management at UH Manoa! My research involves developing the relationship between experimental tropical soil warming and carbon release into the atmosphere. This study will mimic the warming effect of climate change as predicted for 2100 and provide insight into the changes global temperature rise might bring into the natural carbon cycle. Aside from being interested in the effects of soil warming on carbon flux, I am interested in earth systems modeling and analysis through programs like ArcGIS and MATLAB. When I’m not in the lab or up at the research site at the Lyon Arboretum, I love to go backpacking, swimming and swing dancing!
Mathilde Duvallet (intern) – visiting student of ecology and engineering from AgroParis Tech; originally from Normandy, France, Mathilde is conducting her international internship requirement in the Crow Lab. Her primary duties are to assist in the connection of deep soil heating probes through an complex electrical network which creates heat within the deep soil profile using heating cable and installation of the novel temperature sensor network. The temperature network includes wiring the sensors to multiplexors to a data logger in order to collect temperature data. In addition, she will assist in the collection of soil cores, analysis of the microbial communities at the study sit and soil gas flux sampling.
Genelle Watkins M.S. 2018 NREM Interests in conservation and sustainability took Genelle to Pemba Island in East Africa where she worked with local communities to develop a strategy to conserve and restore mangrove forests to help maintain livelihoods. Her passion for sustainability and hope to better this planet through citizen science research that directly involves people and communities to make a positive global impact will take her far. As a start, Genelle currently works for Hawaii Green Growth developing content for the Aloha+ Challenge Dashboard.
Kaelin Sylva B.S. 2018 NREM Kaelin completed her internship assisting with field site planning, maintenance, and characterization for the deep soil warming project at the Lyon Arboretum and transitioned to research assistant, making everything run a little smoother for all of us in the Crow lab.
Annika Little B.S. 2017 NREM Annika conducted her NREM internship in the Crow Lab and completed independent research on the distribution of biochar in soil aggregates in a zero-tillage perennial grass system. She currently works for the U.S. Army Medical Command in the Forensic Toxicology Drug Testing Laboratory and a Specimen Controller.
Steven Leone 2017 Steven worked with the Crow Lab throughout 2017 to help convert an overgrown jungle patch into a Deep Soil Warming field site for a long term, manipulative experiment to test the effect of warmer soil on ecosystem processes and carbon biogeochemistry. He developed the temperature sensor network for the field site at the Lyon Arboretum and this website.
