Global warming is a phenomenon where the air and sea water temperature raise globally due to the greenhouse effect. It occurs because some gases have the ability to absorb the radiant energy from the sun, converting it into heat and which warms the air temperature. The major greenhouse gases are: water vapor, carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). These gases are mostly known by human activities, but they can also be released from natural environment.
Ecological engineering technology has been widely used for waste water treatment, habitat restoration, ecosystem remediation, or storm water management. Wetland is one type of ecosystem that can be designed for these purposes. Aquatic plants in wetlands absorb inorganic nutrients from water, which can help remove excess nitrogen and phosphorus. However, promoting nutrient removal from polluted water may also increase greenhouse gas emissions. With different nutrient conditions and management practices, the greenhouse gas emissions and related soil microbial communities in these constructed wetlands can be different comparing to those in pristine wetlands.
My research is focused on the biogeochemical processes related to greenhouse gas emissions, C sequestration and nutrient removals in natural ecosystems, and the responses of these processes to climate change and global warming.
For perspective students who are interested in soil biogeochemical processes, please contact the PI at "yshiau@ntu.edu.tw". Tuition waives and stipends will be available for succeeded applicants pursuing MS or Ph.D. degrees.
The application is typically due in December.
