Xing first visited our field site. His first visit was Cherwon rice paddy site! This photo was taken at ~1 m.
Youngryel's birthday. Thanks for all of you!
Sangjun and Jeongho visited Jeju site for checking our hyperspectral system
August
Time flies! This is the 10th year anniversary of the lab! Congratulations for all!
We have made a new lab webpage, and renamed the lab: Ecological Sensing AI Lab!
Jeehwan's manuscript, entitled "The magnitude and causes of edge effects on soil organic carbon stocks within and across urban to rural forest patches" has been accepted for publication in Landscape and Urban Planning. Congratulations!
Hyperspectral+lidar drone data were collected in a rice paddy and deciduous forest!
Drought experiment was conducted via teamwork! Yorum, Jongmin, Tackang and Ryoungseob worked together
We had a farewell party for Vaibhav. He has been working on mobile lidar+vision system over 1 year 10 months. He will return to his home country, India!
Youngryel started an Associate Dean position (2 years term).
Ecological sensing workshop was held at Jeju Island. Workshop and field trip to the flux tower site.
July
We will have a new postoc, Zilong Zhong! His background is computer science/vision/ML. He will join the lab this Nov. Welcome Zilong!
This is a really hot summer, but our field works continue. Below is Yorum and Jongmin's drought experiment.
Ryoungseob made a new lab logo!
Tackang joined the lab as a research intern, and will start Master course from this Sep. Welcome Tackang! He will take the lead mobile ecological sensing platform.
Jongmin is a MacGyver. It is his hand-made ChlF system!
June

Jeehwan is processing a lot of soil samples from urban deep places.
Drought experiment! Yorum, Jongmin, Sangjun prepared a lot of necessary things.
Ryoungseob's new toy, Leica LiDAR is now in the urban park. He is scanning a lot of trees.
We secured a new space! As there is no windows, we call it, Deep Space Lab (DSL). It will be very helpful to achieve social distance across lab spaces.
March
Henock Mamo started as a Software Engineer! Welcome!!
Jongmin’s ENF SIF paper has been published in Remote Sensing of Environment! Congratulations!!

Ben Dechant is leaving the lab. He will start a new job at Leipzig in Feb. We prepared several events for him! We will miss you Ben-
This winter brought a lot of snow! This is one day from my office.
Folks prepare/manage new hyperspectral system in Gwangneung flux tower.
Ben did his final field trip to Cherwon rice paddy site.
I found your insights on environmental changes really thought-provoking! How can we engage younger generations, who are often captivated by popular games, in sustainability efforts? Could gamification be a bridge to inspire eco-friendly behaviors?
A standout feature of moto x3m is how some levels require precise stillness to survive. Waiting calmly for moving obstacles to pass creates suspense and makes success feel incredibly rewarding.
Ben Dechant is leaving the lab. He will start a new job at Leipzig in Kart Bros IO. We prepared several events for him! We will miss you Ben-
About game Football Bros IO, it delivers fast-paced football action that’s easy to pick up but hard to put down. With simple controls and chaotic matches, every game feels unpredictable, exciting, and packed with laughs.
In PolyTrack, control always comes before speed. The game challenges players with tight tracks that demand smooth steering and quick reactions. Driving too fast without precision often leads to failure. To win, players must learn how to balance acceleration with careful movement, turning speed into an advantage instead of a risk.
