Step into Ecosystem Sciences
In my childhood, I had been most of the time in the hometown of my mother that is a rural village near Mt. Sorac in eastern part of Korea. I loved the landscapes covered by small mountrains, rice paddies, and streams and all animals, trees, and flowers. I was grown up with a hope to be a biologist who seeking cuirosity about the nature and a wish to keep in touch with beautiful motherland of nature. They are solid motivation in my school years to stick my mind in doing sciences. Now I am studying ecosystem sciences (more specifically ecosystem ecology) looking at ecological processes between biological and environmental interactions over the globe. The fields I am interested in within ecosystem sciences are biogeochemisry, landscape ecology, and hydrology.
- My resaerch interests lie in the areas of biogeochemical cycles, eco-hydrological modelling, landscape ecology. The specific subjects of the research are:
1) The biogeochemistry of carbon and nitrogen in terrestrial ecosystems
2) Terrestrial carbon and nitrogen dynamics associated with climate and land cover changes
3) Experimental and model-based research on greenhouse gas fluxes and dissolved carbon and nitrogen from terrestrial ecosystems
4) Landscape or regional modelling of carbon and nitrogen exchange using geographic information system and remote sensing data
5) Characterization of landscape formation and ecosystem attributions (e.g., topography and leaf area) to affect terrestial biogeochemistry
- Modelling greenhouse gas exchanges from the reservoir surface and improving an existing reservoir model for reservoir carbon exchange are the major subjects as my postdoctoral research. The study area is the Eastmain-1 reservoir in Northern Québec, Canada (See photos in the field) which completed in 2006.
- Tasks for my PhD were developing an ecosystem model for carbon cycling of reservoirs and simulating carbon flux from a hydroelectric reservoir in the boreal biome (same site as for the postdoctoral study). These tasks produced my Ph.D. thesis (Kim Y. 2011. Modeling and experimental analysis of carbon exchange from artificially flooded boreal forest and peatland ecosystems. Ph.D. Thesis. McGill University, Montreal, Canada) and prepared four manuscripts to be submitted to journals. Electronic file of my thesis (pdf format) is available upon your request.
- I have investigated carbon cycling in forest ecosystems in the cool-temperate zone of Korea to pursue my Master's degree. This study have conducted to know the variablity of the forest productivity and the main factors that affect the productivity. These worked produced my M.Sc. thesis (Kim Y. 2006. Annual growth of standing biomass estimated with tree-ring data and biometric equation at a Gwangneung deciduous forest, Korea. M.Sc. Thesis. Seoul National University, Seoul, South Korea). Electronic file of this thesis is available upon your request.
Research activities to do main tasks of my research: Laboratory experiments of greemhosue gas flux (left); sampling of field materials (e.g. organic/mineral soils) (center); measurements of the biophysical factors in the ecosystems (right); ecological modelling to simulate nutrient cycling and greenhouse gas exchange from the ecosystems (photo missed)
