At the Latnjajaure Research Station. We surveyed the catchment, collected water, soil, and vegetation samples, and explored hydrological processes across this Arctic-alpine watershed. Grateful for the opportunity to work with researchers from around the world in such an inspiring natural laboratory.

Arctic summers are surprisingly green. Under the midnight sun, daylight lasts around the clock and the sun barely sets. Our field campaign focuses on understanding how alpine tundra plant uses water in a changing Arctic, and how these ecohydrological processes may respond to ongoing climate change.

Visited the Krycklan Catchment Study today, one of the world’s most intensively monitored boreal catchments. I couldn’t help but wonder: has anyone ever estimated how many trees grow in the entire Krycklan catchment? #Krycklan #Hydrology #Ecohydrology #BorealForest #Sweden

Excited to share our recent publication in Water Resources Research: “The Role of Rock Fractures as a Water Source for Trees Growing in Karst” Full article: lnkd.in/g4yQD3N3 This work improves our understanding of ecohydrological processes in karst systems. #Karst #Ecohydrology #ClimateChange

Glad to share our new paper published this week in Hydrology and Earth System Sciences (HESS): “Rock fracture characteristics regulate water storage and seasonal tree water uptake in karst” Paper link: lnkd.in/d2mmtpQJ DOI: 10.5194/hess-30-3061-2026 #Karst #Ecohydrology #StableIsotopes #Hydrology

Polar light in Arctic!

The Louvre is the world’s largest art museum and a symbol of Paris. In one day, start with the iconic glass pyramid, then focus on highlights: the Mona Lisa, Venus de Milo, and Winged Victory of Samothrace.

Global Warming Is Real

I’ve used CVD extraction systems in China and Canada, and now revived an old one in Sweden that hadn’t run for four years. No instructions, no one remembered how it worked, so I relied on experience and finally got water out again. A small but very satisfying win. Lab archaeology is real.

Our new paper shows that trees in karst rely heavily on rock-fracture water. Stable fracture moisture keeps transpiration steady and buffers drought, while limited storage forces strong wet-season water use. Rock fractures are a key, overlooked driver of plant water strategies under climate change.

I’ve just joined the Department of Ecology and Environmental Science at Umeå University, Sweden! 🇸🇪 My postdoc research will focus on plant water use and evapotranspiration in Arctic ecosystems using isotopes and hydrological monitoring. Umeå lies in a beautiful forest, and fika tradition is so cozy.

Happy PhD Graduation to me!

Happy PhD Graduation!

Just attended the China Annual Conference on Hydrology and Geographical Sciences — deeply impressed by the field visit to a national research station. Massive soil columns and a manually excavated 45-meter deep borehole, monitored every 20 cm, with an elevator to the bottom.

Just passed my PhD defense successfully! Grateful for all the support along the way — supervisors, collaborators, and friends. Looking forward to the next chapter in ecohydrology research!

We estimated epikarst hydraulic conductivity (Kh) using slug tests. Steady-flow models underestimated Kh, while non-steady simulations worked better when Re > 17. Soil-filled fractures shaped flow paths, revealing key controls on water availability in karst. #karst #hydrology

New study: We examined how heterogeneous soil–rock structures affect subsurface stormflow in karst. Thicker soils reduced outflow, porous gravels boosted evaporation, and rainfall intensity flipped flow paths. Key insights for modeling runoff in complex terrains. #hydrology #karst

Gave a presentation on the island in the Danube River, Vienna. Great discussions with fellow researchers — left with new ideas and fresh inspiration.#egu25

Excited to present at #EGU25! Join me for my talk “The role of rock fractures as a water source for trees growing in karst” 🗓️ Monday, 28 April 🕒 14:55–15:05 📍 Room 2.44 Looking forward to seeing you there! #EGU2025 #Hydrology #Karst #Ecohydrology

Attending EGU25 brought me to the beautiful city of Vienna, a place filled with history, music, and art. I was especially thrilled to visit my favorite art museum, where every masterpiece offered a profound dialogue with the past.

Montreal, the “Little Paris of North America,” is full of French charm. The city’s style is quite similar to Harbin, with a touch of cyberpunk. The churches are beautiful. Here, French is more prevalent than English, making it quite challenging to understand the signs.
