- Philosophy Statement
I am interested in diverse aspects of landscape ecology and its potential to inform sustainable, multi-functional landscape-designs, and decision-making in environmental planning. My research combines field ecological methods with remote sensing, geographic information systems (GIS) and spatial analysis to perform analyses of multi-scale structure of ecosystems, to facilitate scaling of ecological processes from local to regional levels and to develop remote sensing-based monitoring approaches for vulnerable areas and sites with limited field access.
1) Dynamics of wetland vegetation and ecosystem services in California's Sacramento-San Joaquin Delta (the Delta). Both in the Delta and globally, emergent wetland plants control important ecosystem processes (e.g., aboveground productivity, greenhouse gas fluxes and subsidence-counteracting belowground peat storage), habitat for birds and other wildlife and recreational, aesthetic and cultural values to humans. Changing climate, increasing demands for water, alien species invasions and other pressures create urgent needs to better understand multi-functionality of wetland canopies and their response to change drivers in order to develop sustainable management and planning strategies for the multi-functional Delta landscape. In our group we are taking advantage of the rich remote sensing and geospatial data libraries and diversity of wetland field sites in the region to interpolate important biophysical characteristics of wetland canopies such as leaf area index and better understand their response to climate, hydrology and recent land use history.
2) Effects of city environment on urban ecosystem services. It is well known that urbanization affects landscape carbon and energy balance by reducing green plant cover while creating more fertilized environments for remaining and new vegetation, and by increasing impervious surface and forming strong thermal gradients within city areas. However, much uncertainty still exists on how the relationships between physical properties of urban environments and ecological function of urban vegetation change over time with the dynamics of urban landscapes, and how they vary across different metropolitan areas of the world. Combining time series of satellite remote sensing with ground-based data on urban ecosystem structure is a promising venue to investigate these complex feedbacks and links between broad-scale urban structure and ecological services of specific sites and their designs.
3) Coupled thermal-vegetation patterns as indicators of development and socioeconomic context in urban regions.Among various benefits of urban vegetation, local cooling and improvement of thermal comfort are especially well-known in light of elevated heat loads in built-up environments. What is not well understood, however, is how these benefits vary with different urban morphologies and socioeconomic contexts of development. Using repeatedly collected optical and thermal satellite imagery, we can characterize spatial patterns of green vegetation cover and surface temperature proxies and develop the indicators of urban environment that may elucidate the character and broader context of development. Such indicators are especially needed in data-scarce regions and locations where the outcomes of development create substantial risks to human well-being and vulnerability to climate change and hazards.
I have a PhD in Environmental Science, Policy and Management from UC Berkeley in 2012, a M.S. degree in Natural Resources/Terrestrial Ecology and Management and a Certificate in Spatial Analysis from the School of Natural Resource and Environment at the University of Michigan, Ann Arbor in 2004 and a B.S. degree in Ecology from the National University of Kyiv-Mohyla Academy, Ukraine in 2001. My previous research included applications of vegetation and landscape ecology, remote sensing and geographic information systems (GIS) to study ecosystem properties and change in grasslands of Ukraine, transitioning forests of northern Michigan, USA, large wetland biodiversity hotspots in PR China and California, USA. My current research focuses predominantly on wetland systems and urbanizing landscapes in California and globally.
