My research interest lies in measuring and modeling the physical processes involved in the soil-plant-atmosphere continuum, with a special focus on energy and mass exchange measurement between surfaces (bare soil, vegetated, wet-lands and/or water) and the atmosphere using micrometeorological methods. I am interested in investigating energy balance closure using eddy covariance measured fluxes; and also the influence of land-use and climate changes on heat, carbon dioxide, water vapor and other trace gas fluxes.

My previous studies concentrated on measurement and modeling of crop growth and development, soil water balance, solar radiation and its interception by shrubs, and evapotranspiration from sparse trees. I was also involved in investigating inexpensive means of estimating sensible heat flux from high frequency air temperature measurements.

I'm involved in an integrated research on the Life Cycle Sustainability Assessment of photovoltaic technology and its production. The study is divided into Environmental Life Cycle Assessment, Life Cycle Costing, Social Life Cycle Assessment, and comprehensive structural equation modeling (SEM). To accomplish the assessment, structural equation modeling will be intensive used in the research. My goal is to explore innovative and efficient PV pipelines to meet the growing and changing demands for efficient PV technology and production, renewable energy, and ecosystem services for society and to examine how existing trade-offs differ from other energy revenues.

Visiting Scholar | University of Bari, Italy
E-Mail: vincenzo.giannico@gmail.com

Vincenzo Giannico is a PhD candidate in "Biodiversity, Agriculture and Environment” at the Department of Agriculture and Environmental Sciences (DISAAT), University of Bari. His doctoral research focuses on ecosystem service trade-offs of urban and peri-urban forest areas using high resolution remotely sensed data (i.e. LiDAR, Multi- and Hyperspectral data).

Specifically, the aim of his research is to find explanatory variables derived from remote sensing data capable of estimating carbon stored in biomass, the amount of biodiversity and its patterns, and to understand the relationships among these ecosystem services. Previously, he did an internship in "Planetek Italia", a leader company in the field of Earth Observation technologies, where he performed pre-processing and advanced analysis methodologies on optical and laser sensor data and more. His main research interests are ecosystem modeling, ecosystem services, remote sensing of the environment, and applications of geomatics in forestry.

Research Associate

Ranjeet's research interests focus on the applications of Remote Sensing and Geospatial technologies to study biophysical attributes that include carbon, water and energy fluxes at varying scales in context of ecosystem ecology, land cover/land use, and climate change. His current position in the LEES lab requires him to synthesize existing meteorological and medium to coarse resolution satellite derived-data (for e.g., drought indices, extreme climate anomalies & non-parametric trend analysis). In addition, his research also involves scaling up from in situ observations from various eddy covariance flux towers and standard ground truth methods to a regional scale in context of rapid climatic and socio-economic changes (in the Mongolian Plateau and elsewhere).

Dr. Raffaele Lafortezza is Adjunct Professor at the Center for Global Change and Earth Observations (CGCEO), Michigan State University. He holds a PhD in Landscape Ecology and Planning from the University of Bari (2002) and has accumulated considerable experience in landscape ecology issues by participating in numerous research projects and scientific collaborations conducted worldwide. His main research interest lies in the fields of landscape modeling at multiple spatial and temporal scales, sustainable land management in the context of global change, ecosystem services associated with green infrastructures and nature-based solutions, quantitative assessment of biodiversity, and analysis of ecological disturbances, including forest fires and fragmentation in wildland urban interfaces. In addition, he seeks to understand the impact of human activity on ecosystems (i.e., coupled human and natural systems) and to discover methods for preserving ecological patterns and related processes/services.

Dr. Lafortezza has developed his research interests in the United States (University of Toledo, Michigan State University), Canada (University of Guelph), Japan (University of Tsukuba, University of Tokyo), and the United Kingdom (University of Cambridge) and has been involved, as principal- and co-investigator, in many research projects. He is Associate Editor of the journal "Urban Forestry & Urban Greening” (Elsevier) and a member of the Editorial Board of the Springer journals “Landscape Ecology” and “Ecological Processes”.

My former research focused on mapping and investigating invasive plants in wetlands (such as Spartina alterniflorain east coast of China by remote sensing techniques and GIS. Currently, my research interest has moved on to carbon fluxes of terrestrial ecosystems, as I think carbon related problems such as greenhouse gases, carbon storage and cycling , and so on are core issues of global climate change. I love science, but I also like many other things, like cycling, swimming, playing ping-pong and reading.

My research interests aimed at understanding human-environment interactions through a focus on land-use and land-cover changes through using eddy covariance technique in grassland ecosystems: from observation to data analysis of carbon, water and energy fluxes. I have been the one maintaining two mobile flux towers in Inner Mongolia for 3 years and opened the eddy covariance data in public via internet. Recent work has used two mobile eddy flux towers to study different disturbance ecosystems under the same environment, which is valuable for modeling precision, and contribute us to understand the underlying effect mechanism through different management types. I have served the NASA LCLUC Science Team, the NSFC and the Foundation of Chinese Academy of Sciences. In 2009 I was elected fellow of the US-China Carbon Consortium (USCCC).

My research interest focuses on the relationship between the metabolism of ecosystems and the environmental regimes and how the relationship responds to human land use and climate change.

I would like to explore the relationship from both ecosystem and community perspectives.The former concentrates on the intrinsic mechanisms within a community, such as how biodiversity, foodweb structure, community dynamics and the species interactions adapt to environmental regimes and maintain the stability of the system while latter focuses on the energy and material transfer and flux within and between ecosystems and their adjacent environment. My research is currently funded by the Great Lakes Bioenergy Research Center (GLBRC) and focus on how crop types and land-use history impact the metabolism of bioenergy agricultural ecosystems. We monitor the carbon sequestration by eddy covariance (EC) techniques and some budget-related ecosystem functions, including aboveground net primary production (ANPP), belowground net primary production (BNPP), photosynthesis rate and soil respiration in corn and switchgrass farms which converted from conservation reserve program (CRP) and conventional agricultural zones near Kellogg Biological Station (KBS), Michigan.

I joined the team in fall 2013 to pursue my Ph.D. study in the research area of life cycle sustainability assessment. I have bachelor degree in Agronomy and Master degrees in Environment and Energy Studies. During my Master study, I grew interested in the Life Cycle Assessment (LCA). After graduation, I began working on LCA related topics in China (e.g. eco-design, carbon footprint) and I found that the popularization of partial LCA enables many companies to use “halo effects” which jeopardizes the company as they may “green wash” by claiming a product system as “green ” simply because it has a superior sustainability than something else. Thus, a holistic way of assessing product systems' overall sustainability is needed in order to help the industry better understand their current performance and improve policy.

The topic which Professor JiQuan Chen and Doctor Defne Apul are working on is very interesting to me. They are conducting life cycle sustainability analysis of proposed photovoltaic technologies and comparing them to different alternatives.

I am excited to begin my work here and study this most interesting, and interdisciplinary, topic.
