Reflecting on the Tenure Track From Mid‐Career

open access: yesPerspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract In this essay, I share ideas on why and how my career has worked for me. I have built a research program around the intersections of the carbon and water cycles with a particular focus on sustainable rice production. Throughout the essay, I include some of the lessons I wish I had discovered sooner.

Bridge Clogging by Loose Sediment in Mountain Streams: A Practical, Physics‐Based Numerical Approach for Use in Hazard Mapping

open access: yesJournal of Flood Risk Management, Volume 18, Issue 4, December 2025.
ABSTRACT The clogging of bridges by loose sediments is a phenomenon that has so far been little studied in the literature but plays a decisive role in determining the spatial distribution of hazards in mountainous areas affected by these events. Lacking a systematic approach, in this paper, we propose a simple scheme describing the physics of bridge ...

Exposed weapons: A revised reconstruction of the facial anatomy and life appearance of the saber‐toothed cat Megantereon (Felidae, Machairodontinae)

open access: yesThe Anatomical Record, Volume 308, Issue 11, Page 2924-2943, November 2025.
Abstract Megantereon was a widespread saber‐toothed felid from the Pliocene and Pleistocene of the Old World and North America, but its rarity in the fossil record makes it complicated to restore its life appearance. Lack of complete specimens makes it necessary to combine information from fossils of different individuals to reconstruct their facial ...

Observing Fine‐Scale Lake Ice‐Out Dynamics in the Lower Kuskokwim River Basin, Alaska

open access: yesHydrological Processes, Volume 39, Issue 11, November 2025.
In this study, we use 10 m Sentinel‐2 satellite imagery to assess fine‐scale patterns in lake ice‐out timing in 145 955 lakes as small as 0.001 km2 in the Lower Kuskokwim River Basin in southwest Alaska over 2018–2023. Lake ice‐out timing varies by nearly one month during our six‐year period, driven primarily by spring air temperature.

DARTS: Multi-year database of AI-detected retrogressive thaw slumps in the circum-arctic permafrost region

open access: yesScientific Data
Retrogressive Thaw Slumps (RTS) are widespread mass-wasting hillslope failures triggered by thawing permafrost. While regional studies have provided insights into the spatial distribution and dynamics of RTS, a consistent and unbiased quantification and ...

Lake changes and their driving factors in circum-arctic permafrost regions from 1990 to 2022

open access: yesEcological Indicators
The rapid increase in temperatures and escalating human activities have led to a reduction or even disappearance of the thickness of the permafrost layer around the Arctic.
