Principal Research Interests:

        My research focuses on the interactions among atmosphere, biosphere, and human dimension in the context of climate change, chemical element cycles, and policy-making. To study these interactions, I use a systems approach that integrates the basic principles of biology, physics, and chemistry. My primary research is to integrate the knowledge derived from field and laboratory experiments with theoretical and computational techniques to advance ecosystem sciences.

 

        One of my major research activities is on carbon exchanges between terrestrial ecosystems and the atmosphere.  I began studies in this area during my dissertation in University of Alaska.  While the growing body of evidence indicates there are profound changes of climate in northern high latitudes, I was struck by the dramatic changes of permafrost and soil thermal regime and their influences on carbon dynamics in the region. Consequently, I spent several years investigating how changes of soil thermal regime, including permafrost melting, affect the carbon assimilation and decomposition in the region.  I was also intrigued by the increase of wildfires in northern ecosystems and their consequences with respect to carbon and nitrogen cycling.  To explore the fire questions, I used modeling as a tool to examine the interactions between fire disturbances and their effects on soil thermal dynamics, hydrological dynamics, and carbon and nitrogen cycles in boreal forests.

 

        My second major research activity is on modeling trace gas emissions from ecosystems and their effects on climate and society. I’ve modeled methane exchanges between ecosystems and the atmosphere by considering the effects of permafrost dynamics, hydrological and vegetation dynamics on methane cycling. The model of methane dynamics I developed has been tested and validated by using observations from a variety of ecosystems at different geographical regions.  As a case study, the model has been applied to Alaska to examine the responses of methane emissions to the climate change.  The model has also been applied for the past and 21st century to study methane cycling in Northern Hemisphere.  Now I am collaborating with a number of colleagues in the US and Canada to model the methane dynamics in temperate and tropical regions. In addition, I have been also actively modeling nitrogen gas (e.g. N2O) emissions from terrestrial ecosystems.

 

        Recently, my research interests were expanded to analyzing consequences of ozone damage and other pollutants for ecosystem services and the economy.  For example, I’ve been involved in several studies using a biogeochemistry model, Terrestrial Ecosystem Model (TEM) and MIT’s Integrated Global System Model to investigate the ozone effects on net primary productivity and carbon sequestration for the continental US and the globe. The research concluded that the effects of ozone should be factored into future calculations of the US carbon budget.  At the global scale, tropospheric ozone effects on ecosystem dynamics and the interaction with climate policy produce a large feedback to estimating climate policy costs. This feedback had not been quantified before.

 

        More recently, I, my students and post-docs got interested in examining the biogeochemical and biophysical feedbacks on atmospheric climate and chemistry with an approach of coupling a number of biosphere and atmosphere models.  Example researches include a number of projects focusing on Northern Eurasia, North America, and Pan-Arctic region funded by DOE and NASA as well as NSF.   These studies are collaborative efforts with MIT, DOE labs, and a number of other institutions in the U.S. and other countries.

Position Openings:

Graduate Students

       The Ecosystems and Biogeochemical Dynamics Laboratory (EBDL) at Purdue University is seeking one/two graduate students starting Fall, 2010, who are interested in (1) modeling feedbacks between the biosphere and atmospheric climate and chemistry and/or (2) modeling water, carbon and nitrogen cycling in terrestrial ecosystems including agricultural ecosystems. Students majored in ecosystem sciences, atmospheric sciences, agronomy and other related fields with proficient mathematical and computational skills and interests in pursuing PhD programs are preferred. The students will have the opportunity to interact with faculty members, scientists, and students in the Department of Earth & Atmospheric Sciences and the Department of Agronomy as well as the Purdue Climate Change Research Center.  Interested students are welcomed to contact Prof. Qianlai Zhuang at qzhuang@purdue.edu

Post-Doctoral Scientist in Ecosystems and Biogeochemical Dynamics

       The Ecosystems and Biogeochemical Dynamics Laboratory at Purdue University is seeking a Post-Doctoral Scientist. The responsibility of this position is to apply a range of skills in ecosystems sciences, remote-sensing and GIS techniques, programming, and mathematics to address large-scale questions of ecosystem and biogeochemical dynamics.  Proficient mathematical and computational skills and demonstrated works in the field of impacts of soil erosion on ecosystem dynamics are preferred. The initial funding for the position is for one year with potentially renewable for the second year depending on funding resources. The position will start in January, 2008.

      The post-doc scientist will have the opportunity to interact with faculty members and scientists in Department of Earth & Atmospheric Sciences and Department of Agronomy as well as the Purdue Climate Change Research Center. Please send an application letter, CV, and names and email addresses of three references to Dr. Qianlai Zhuang at Department of Earth & Atmospheric Sciences and Department of Agronomy of Purdue University (qzhuang@purdue.edu).  Applications will be received and evaluated until the position is filled.  Purdue University is an Equal Opportunity/Affirmative Action employer.
