IMG_5022Dr. Susan E. Crow is an Assistant Professor of Soil Ecology and Biogeochemistry in the Natural Resources and Environmental Management Department within the College of Tropical Agriculture and Human Resources and an affiliate of the Water Resources Research Center at the University of Hawaii Manoa.  She studies the natural carbon cycle and human impacts on the soil environment and serves as a co-PI of a USGS Powell Center Working Group “What lies below” and member of the Kukaniloko Master Planning Working Group and the state Carbon Farming Task Force.  Crow is an associate editor for the journal Biogeochemistry and belongs to the American Geophysical Union, Soil Science Society of America, Soil and Water Conservation Society, and International Soil Carbon Network.

IMG_0990Christine 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.

Current Students:

 Bio_WellsJon 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”.

 

 

Bio_Richardson

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.

 

 

 

Bio_Hubanks

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.

McGrath_pic2_soilandcarbonCasey 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 MathildeTech; 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.
