Two postdoc positions for global land carbon sinks

We are seeking two postdoctoral fellows to work on global land carbon sink estimates. In a newly funded five-year project, we aim to quantify the amount of global land carbon sinks and analyze how they vary across space and time. This project involves international collaborators from UC Berkeley, LSCE, the Carnegie Institution for Science, Columbia University, the University of Reading, Imperial College London, the University of Hong Kong, and CREAF. The project provides mobility funding to visit these institutions and/or invite collaborators, ensuring abundant opportunities for international collaboration for the postdoctoral fellows. 


Specific goals for the two postdoc positions include carbon emissions from respiration and disturbances. The former includes autotrophic and heterotrophic respiration, NPP to GPP ratio which depends on forest age and soil nutrients, and biomass production vs NPP. The latter includes fires and land cover/use change. Various tools and methods will be deployed, such as satellite remote sensing, atmospheric inversion, high-resolution LULC maps, process-based model, and FLUXNET/SRDB-informed data-driven models. These tasks are closely interconnected with other carbon components, offering abundant freedom to explore new topics within the umbrella of global land carbon sinks.


Collaboration will be essential to tackle these significant tasks. Other lab members are working on photosynthesis, image processing, and forest biomass, providing abundant opportunities for internal collaboration. Our international collaborators bring expertise in various tools and topics, which will further facilitate international collaborations.



  • Excellent skills in programming at least one of Python, R, MATLAB

  • Big data processing/analysis (e.g. Google Earth Engine, FLUXNET) with strong quantitative skill

  • PhD in remote sensing, or biometeorology or ecophysiology

  • Moderate (or better) level of English speaking/writing

  • Excellent communication skills internally (lab) and externally (international collaborators)

  • Ability to work independently and to collaborate with others


  • Writing journal papers 

  • Presenting research outcomes in scientific meetings

  • Writing annual project report

  • Mentoring graduate students 

Contact to Youngryel Ryu ( if you are passionate for those topics, have great ideas to understand this complex challenging task, are learning animal, and are willing to join our adventure towards the vision, “a sustainable world where ecological information is available and accessible to anyone.”  I will request cover letter, CV, and the names and contact information of three references. The positions are available immediately and will be open until filled. 


Seoul National University is located in the Gwanak Mountain, southern part of the Seoul City in South Korea. Numerous mountain trails are accessible in the campus whereas “Gangnam”, the center of amusement in Seoul, is within 30 min. There are diverse groups of international students/scholars. There is a dormitory for international scholars which offers low cost, nice housing for family or single.

If you have any question, feel free to send emails to Dr Ryu. Welcome to visit our lab webpage to see our research and activity (
