Our lab's mission is to understand the links between optical, biochemical and functional traits of vegetation.
Univ. of Helsinki, Finland
Joined August 2016
This week in @Nature, on our long-term field observation in @HyytialaHY, @INAR_fin, @ForestSciences. Collecting key data to understand link between radiation and plant physiology.

We join CREDIBLE action to build carbon farming markets and policies we can trust!. @helsinkiuni takes the lead in the focus group of proximal sensing and digitalization for carbon farming. Interested in joining the focus group? .➜ @PaulinaRajewicz

Season's greetings from OPL! Tested: 1)Red #Poinsettia leaves absorb PAR but do not fluoresce👉they do not photosynthesize, 2)We have a fluorescent logo😮! No wonder #SIF is great at capturing the optical expression of photosynthesis in its purest state. @ForestSciences,@INAR_fin

We are proud to share our @NaturePlants Perspective on solar-induced chlorophyll fluorescence: what is it? what could it be used for? what are the next steps? Check it out: @INAR_fin @viikki_plants @ForestSciences @SuomenAkatemia

Brainstorming sessions today at #FAST2019WS @HyytialaHY around our #Fastcam17 multiscale #fluorescence campaign results. Themes: Molecular/Leaf, Canopy/Ecosystem and Modelling. Trying to find a common language from photosystems to global models. #remotesensing @Suomenakatemia
