Naomi is a PhD student working on Antarctic glacier dynamics. She is utilizing multiple remote sensing datasets (Landsat, SPOT, ICEsat-1 and 2, DEMs, and more) to evaluate the changes of tributary glaciers post-ice shelf collapse. Her main research focus is to help crack the mystery of Marine Ice Cliff Instability by analyzing hypothesized ice cliff failure events at Crane, Hektoria, Dinsmoor-Bombardier-Edgeworth, and Röhss glaciers in the Antarctic Peninsula.
I am interested in understanding the mobility of landslides and their evolution by integrating machine learning techniques in remote sensing. Currently, I am focused on southern Chile due to its dynamic climate and environment, where I work to develop a method to identify landslides using digital elevation models, vegetation indices, and amplitude data from satellite radar.

Using Satellite Measurements to Improve Regional Estimates of the Impacts of Sea Level Change.
Changes in sea level already impact coastal communities through erosion, storm surge, saltwater intrusion, and other effects. Projections of future rise have even more dramatic implications, with relatively small rises potentially displacing millions of people. Though the sources of sea level rise are generally known, the specific details of steric and nonsteric contributions are poorly constrained, as is the regional variability that is subject to a myriad of influences, such as ocean currents, lithospheric motions, and global gravitational effects.
The Interaction of Mass Movements with Natural Hazards Under Changing Hydrologic Conditions.
We assess the interactions between mass movements, extreme precipitation, wildfire damage, and earthquakes and the potential for some sequence of these natural hazards to cascade into large-scale disasters. In order to accomplish this goal remote sensing data, optical DEMs, drone-based surveys and in situ data are used with physically-based models to study specific regions and events.

Contributions of Glaciers to Sea Level Rise Over the Past Half-Century
The largest source of eustatic sea level rise during the past century is mass loss from land ice (ice sheets and glaciers) through meltwater runoff and solid ice discharge to the oceans. Both glacier and ice sheets play an important role in sea level change; Ice sheets contain nearly all of the Earth’s land ice (>99% by volume) and will likely dictate changes in sea level rise over the next millennia, while glaciers only contain enough ice to raise global sea levels by 0.4-0.6 m if melted entirely.
I use satellite, aircraft and ground based remote sensing along with spatial data science and glaciohydrologic field methods to study ice sheet and hydrologic dynamics in terrestrial and cryospheric Polar regions. Currently working at NGA.
Characterizing the evolution of the 2014 Vulcan Creek landslide-dammed lake, Yukon, Canada – using field and remote survey techniques, led by Marc-André Brideau has been published
The Vulcan Creek landslide occurred in southwest Yukon in the fall of 2014. No distinct trigger was identified for this landslide; however, contributing factors include the long-term seismicity of the area, 10 °C warmer than normal air temperature in January 2014, and approximately twice the normal rainfall for the month prior to the landslide. Long-term permafrost degradation could have also contributed to the slope instability. The landslide dammed Vulcan Creek, forming a lake with a maximum surface area of ~ 22,000 square meters.
