Biography

I study landscape changes in armed conflict zones and disaster settings with satellite radar data, cloud computing, and methods from the geosciences.

My work is featured in reporting from publications including the New York Times, Financial Times, Washington Post, BBC, CNN, NPR, NBC, Bloomberg, AP, and cited in reports from international humanitarian organizations. I’ve been interviewed about mapping wartime damage by organizations including Scientific American, NPR, Marketplace, Undark, Democracy Now, and my alma mater.

I’m a postdoc in the Conflict Ecology group at Oregon State. I also organize with the Conflict and Environment Academic Network and the Decentralized Damage Mapping Group. My research and organizing work contributes to an emergent science and practice of conflict Earth observation, seeking to better understand the environmental consequences of armed conflicts using satellite data.

Projects

Mapping building damage during the 2025 Los Angeles wildfires

Rapid-response mapping of building damage while the Los Angeles wildfires were active and smoke occluded satellite optical imagery.

Mapping building damage in Lebanon and northern Israel

Active monitoring of building damage with escalation of the regional conflict.

Tracking the footprint of war

AGU 2024 Fall Meeting session on the science and practice of conflict impact assessment

Weekly building damage surveys in Gaza

Utilized by humanitarian organizations and cited by hundereds of media reports in publications of record around the world, our data serve an important role in public understanding of the rapid pace and vast extent of the impacts of the Israeli bombardment and invasion on the Gaza Strip.

Mapping damage to human settlements in Ukraine

Coherent change detection for nationwide monitoring of damage to human settlements during the Russian invasion of Ukraine.

‘Sacrificing part for the whole’

Mapping floodwater extent to support investigative journalism at the Washington Post.

Detecting new burial sites in Tigray

Analysis of very high resolution satellite optical imagery with the visual investigation team at the Washington Post.

2023 AGU Fall Meeting Session on Physical and Environmental Impacts of War

Co-convened a session on scientific perspectives on the physical and environmental impacts of war.

NASA Applied Remote Sensing Training in Humanitarian Applications

Co-taught a session for Earth observation practitioners on the use of NASA open-source processing tools for monitoring damage to built-up areas during military conflict.

Subsidence monitoring in transboundary aquifers

I started processing interferometric synthetic aperture radar (InSAR) data in conflict settings in 2015 to measure subsidence patterns in transboundary aquifers. I include a short blog-style post introducing this work and where it stands today.

Fires on land concessions for palm cultivation in Indonesia

Remote sensing of burn patterns in support of an investigation around the intentionality of peatland fires for forest clearing.

Herbicide drift from Israel to Gaza

Remote sensing of decreases in normalized difference vegetation index (NDVI) coincident with Israeli military spraying of herbicide along the Gaza siege perimeter.

Mapping wildfire scars in southern Israel caused by incendiary kites launched from the Gaza Strip in 2018

I tested whether reported wildfire scars from incendiary kites launched within the Gaza Strip could be detected in open access satellite radar and optical data in southern Israel.

Mapping glacier melt signals with satellite radar and scalable cloud computing

My masters fellowship was in support of a NASA Cryosphere program grant to research glacier melt timing and duration across all mapped glaciers in the Hindu Kush Himalaya region.

Researching some of the youngest land on Earth

I had the privilege to help with a research experiment at the edge of some of the newest land on Earth to investigate how plants help to build land naturally along the Louisiana coast.

Leveraging bathymetric LiDAR data to study the geometry of river channels

I had a two-year undergraduate-level research apprenticeship in the Environmental Systems Dynamics Lab at UC Berkeley to study fundamental relationships in how rivers change shape across their course using very high resolution bathymetric LiDAR data.
