    FGI Research Seminar: Ultra precise astrometry with Very Long Baseline Interferometry: from radio star to quasar

    18.11.2025 at 15.00–16.00 (EET)
    Online
    Espoo

    Our second speaker is Dr. Jingdong Zhang. He will tell us about: Ultra precise astrometry with Very Long Baseline Interferometry: from radio star to quasar.

    A precise and stable Celestial Reference Frame (CRF) underpins modern astronomy, geodesy, and related disciplines. Establishing such a CRF relies on high-accuracy astrometric measurements of celestial objects, for which Very Long Baseline Interferometry (VLBI) remains the most powerful technique. This talk will present my work on VLBI-based astrometry of extragalactic sources (quasars) and radio stars, emphasizing their roles in the establishment, maintenance, and multi-wavelength alignment of celestial reference frames.

    FGI Research Seminar: Monitoring forest disturbances and crop traits via advanced drone remote sensing

    24.11.2025 at 15.00–16.00 (EET)
    Online
    Espoo

    This time our speaker is Dr. Raquel Oliveira. The topic of her presentation is “Monitoring forest disturbances and crop traits via advanced drone remote sensing.”

    Climate change is driving major ecological shifts in forests and agriculture, from widespread bark beetle outbreaks to altered crop development. This seminar will present how advanced drone-based hyperspectral data can deliver comprehensive assessments of forest and crop conditions. This presentation is part of our special FGI Research Seminar Series – FGI Postdocs in the Spotlight, where our new Postdocs of the 3-year TULANET Postdoc program will present themselves and their work.

    FGI Research Seminar: Advancing Close-Range Forest Monitoring through Multi-Temporal Point Cloud Processing

    1.12.2025 at 15.00–16.00 (EET)
    Espoo

    This time Dr. Mariana Campos will present her topic “Advancing Close-Range Forest Monitoring through Multi-Temporal Point Cloud Processing.”
    She will show how LiDAR time series can reveal new insights into forest dynamics, with a particular focus on detecting species-specific phenology patterns. The monitoring of these patterns can support investigations on how different species respond to climate change and how shifts in spring timing may influence forest functioning, including growth. She will also discuss LiDAR data-processing strategies designed to overcome the challenges involved on large, multimodal, and multi-temporal datasets with high spatial and temporal resolution.
