Curriculum Vitae

Education

Laura received her B.Sc. Honors in Earth Systems Sciences in 2007 from Queen’s University at Kingston, Ontario. She then moved to the University of Victoria where she received her MSc in Geography in 2009. Her masters thesis was titled ‘Aboveground biomass estimation using spaceborne LiDAR in managed conifer forests in south central British Columbia.’ In 2010 she started her phd at the University of Maryland working with Ralph Dubayah. She defended her dissertation thesis entitled ‘Fusing Allometric Scaling with LiDAR Remote Sensing for Improved Biomass Estimation and Ecosystem Characterization’ in 2014. From 2015 – 2017 she was a NASA Postdoctoral Fellow (NPP) at NASA Goddard working on research related to the upcoming GEDI mission and individual tree level dynamics. She is currently an assistant research professor at NASA Goddard, appointed through the department of Geographical Sciences at the University of Maryland.

Research Experience

Research Assistant Professor (2017-present) Research focuses on global-scale ecology and biomass mapping, primarily in preparation for upcoming active remote sensing missions such as GEDI.

NASA Goddard: NASA Postdoctoral Program Fellow (2015-2017) Research focuses on three main avenues of enquiry: First, support of the upcoming footprint level biomass product for the Global Ecosystem Dynamics Investigation (GEDI), second, an analysis of individual tree structural and functional dynamics across environmental gradients in southeast Alaska, and third, assessing the utility of high resolution stereo optical datasets for forest structural analysis.

University of Maryland: NASA NESSF Fellow (2011-2014) Research focused on applying large field and airborne LiDAR datasets to address questions of forest allometry from both theoretical and applied perspectives.

University of Maryland, Research Assistant (2012-2014): NASA’s Carbon Monitoring System (CMS) is a project focused on developing best practices for local-regional forest carbon mapping and monitoring. Research has been conducted to determine optimal field data collection techniques, lidar processing, and empirical modeling for aboveground biomass estimation across Maryland. My work focused on developing and applying empiral models to predict field estimates of aboveground biomass from lidar metrics, both in Maryland and Sonoma County, California.

NASA Earth Exchange Summer Shortcourse (2012): This summer course, offered at the NASA Ames campus, provided eight students from across the US with one week of exceptional lectures from world leaders in Earth science, and one week of hands-on practice allowing students to conduct their own research on Pleiades, the supercomputer at NASA Ames. Students were granted three years of access to the supercomputing system to expand the scope of their PhD research projects.

University of Maryland, Research Assistant (2010): Assessed the accuracy of global forest height products with airborne LiDAR data, generated gridded North American forest height maps at various resolutions.

University of Victoria, NSERC Fellow (2008-2009): Evaluated GLAS waveform Lidar for canopy height and biomass in high relief areas.

Queen’s University Summer Research Assistant (2004-2006): Field work was conducted in Ontario and the Yukon territory, studying turbidity currents in a glacially-fed lake (Yukon), and forest biomass dynamics (Ontario).
