Remote sensing is a great toolbox, but unless those tools are used to
solve real world problems, there is no reason they should exist.
The problems I am interested in concern human interactions with
natural processes that affect distributions of vegetation, and
the health of that vegetation to support biodiversity. Because
of this, my research focus is on the translation of remotely
sensed data into useful ecological information for process
modeling and resource management applications. Primary
applications include inventory and monitoring, carbon dynamics,
habitat, and biodiversity. By necessity, I focus on the full
spectrum of analyses from calibrating raw sensor data through
the development of land cover and cover change map products
using innovative approaches.Characterizing changes in
information quality as data are coarsened from specific to more
general is a key focus of my research. I remain actively engaged
in exploiting newer sensors data such as lidar, and in
integrating data from multiple sensors with field data for
effective use in ecology. I am on the editorial board of the
journal Remote Sensing of Environment and since the early 1990s,
I have been actively engaged in several aspects of the Landsat
satellite sensor program. Currently, I serve as a member of the
Landsat Science Team, preparing for the launch of the Landsat
Data Continuity Mission early next decade. On the personal
front, I enjoy my family, yoga, old-time music, partying with
friends, improving environmental awareness, peace (as opposed to
war), and social liberalism (no specific order implied).

||I am interested in ecological modeling with remote sensing for landscape and regional ecological information;
forest succession; ecological informatics and application development for ecological researches.
My current work includes linking time series of spectral data with different successional trajectories; spatial modeling of ecosystem production through
BiomBGC modeling; developing methods to quantify uncertainties associated with remote sensing analysis.

Wenatchee, WA, my husband and I to do the things we like to call
fun - playing and watching sports, traveling,
skiing, hiking, and just generally

My major research interest is in remote sensing of the carbon,
water and energy balance of terrestrial ecosystems. I use
remotely sensed observations from towers and satellites to
obtain information about vegetation carbon uptake over land and
relate this data to models of the carbon, water and energy cycle
regionally and globally. A central aspect of my work has been to
scale stand level observations to the landscape where it can be
observed by satellites. This includes links between vegetation
structure and function, which can be obtained for instance using
multi-angle optical systems, but also from airborne and
terrestrial laser scanning (LiDAR) data.

||Research Interests: carbon cycling in forest ecosystems and management strategies for increasing carbon
storage and sequestration, land cover and land-use change, ecology, succession, and disturbance regime of boreal forests, the role of
woody detritus in forest ecosystems including biomass, carbon, and nutrient budgets, Russian environmental history, forestry, forest
resources and their management,
peatlands and their role in the global balance of greenhouse gasses.

With a background
in environmental education, recreation, and land management, I
use remote sensing and geographic information systems to create
maps that show people what is happening on planet earth. My
current work includes validation for the LEDAPS project and
image analysis for the NELDA project. Previously, I have
contributed towards predicting invasive weeds on the Pacific
Crest Trail in southwest Oregon, identifying short vegetation in
the southern Cascade Mountains using LiDAR and Landsat TM,
analyzing effects of the Biscuit Wildfire in southwest Oregon,
and surveying for rare plants. Though I spend many hours
exploring the virtual world, I enjoy exploring the real world,
too. As often as possible, I am hiking, boating, skiing,
traveling, and wandering through the western U.S.
I recently completed my MS degree at
Southern Oregon University studying non-conifer vegetation
patterns in relation to environmental and disturbance variables.
My masters’ thesis work in addition to my earlier field research
in fire ecology, wildlife, and botany, led to an interest in
landscape and disturbance ecology as well as plant and animal
distributions. As a Research Assistant for LARSE I have been
able to continue investigating these interests using remote
sensing and GIS. While working in this virtual world I use my
past field experiences to critically analyze our remotely sensed
products. I am currently validating and performing spatial
analysis on a stand replacement disturbance map of northern
California. I also recently worked on a project monitoring
vegetation changes over time in national parks in southwest
Alaska. In my free time I like to get outside and explore
whenever I can. I enjoy mountain biking, skiing, backpacking,
I work with Dave Turner on the ecosystem modeling component of the BigFoot project. Specifically, I
maintain the data and processes used to model gross primary production (GPP) and net primary production (NPP). My expertise is in the
management and analysis of spatial data.
Previously, I examined the spatial distribution of Port-Orford cedar root disease within the Smith River National Recreation Area, CA.
As one would expect, the spatial distribution is highly clumped (spatially autocorrelated), and the closer a stand is to an existing
infection the more likely it is to become infected. Go figure!
In a past life before heading into the realm of natural resources and ecology, I worked as an application developer for a big computer
consulting company. I wore a suit and tie everyday and helped sell canned fruits and vegetables. I am clearly heading in a better direction.

I am a recent graduate from OSU with a PhD
in forestry (forest biometrics) and my research has primarily
focused on modeling and estimation of forest attributes with
remote sensing – especially with lidar and Landsat. Remote
sensing provides an improved capacity to represent what is
present in forests, although clearly there are many aspects of
modeling and estimation that have yet to be sufficiently
explored. I am interested in research that expands our capacity
do make inferences from remote sensing (or other auxiliary
information) about natural resources, and also in efforts to
transition research ideas to practical usage.
Some things I enjoy on the weekends include
reading a good book, visiting new places in the Willamette
valley, travel, and picking fresh fruit.
My research interests are
primarily in the area of spatially-distributed application of
ecosystem models for carbon cycle analysis. I look to remote
sensing sensors including Landsat, MODIS, and ICEsat for
spatially extensive model inputs. I am particularly concerned
with issues of spatial resolution, algorithm development, and
model validation. Current studies are focused on the carbon
budget of the West Coast of the US and previous studies have
included sites ranging from the Amazon Basin to Barrow Alaska.
In my classes and general science writing I am especially
interested in the global scale relationship of humanity to the
biosphere. I enjoy family and friends, hiking, mountain biking,
playing guitar, and travel.
