Research collaboration, talk invitations, peer reviews, or a coffee if you happen to be in Redlands or College Station.
Email is the most reliable channel. I usually reply within a day. For research collaboration inquiries, please share a brief note describing the question and the data you are working with. That helps me give a useful response.
Most of what I work on comes back to one question — how do cities reshape the planet? — approached from four directions. If your question sits near any of these, I would like to hear about it.
Where cities have already grown and where they are going next, reconstructed from multi-decadal land-cover series and projected under SSP scenarios — from single metropolitan areas through world regions to the global total. Each scale answers a different question, and I care about keeping those differences visible rather than averaging them into one curve.
Transportation usually enters land-change models as a fixed input. My work treats road growth as something to forecast in its own right, because knowing where new roads appear tells you where forests open and where new hazard exposure accumulates.
What urban and road expansion do to species ranges, Key Biodiversity Areas, and the landscapes immediately outside protected boundaries. Increasingly the interesting signal is at the edge rather than inside the line on the map.
How built systems sit relative to flooding and other hazards, and the methodological questions underneath — scale, product choice, validation, and how to report uncertainty when the sample is large enough to make everything significant.
Beyond the areas above, I am glad to discuss potential collaborations, questions about published work, the graduate school and early-career research journey, and Earth and environmental science research more broadly. A short note on your question and the data behind it helps me reply usefully.
