Förnärvarande är mitt focus hur biokol påverkar växter i urbana miljöer. Min forskning handlar generellt sett om hur förhållandena kan förbättras för städernas vegetation och biokol är en möjlig jordförbättrande komponent som är mycket lovande. Hela projektet behandlar hela kedjan från restprodukter, pyrolys och olika urbana tillämpningar (www.biokol.org). Tidigare har jag skapat olika urbana biotoper för att öka biodiversiteten i städer i projektet BiodiverCity. Vi skapade skogsbiotoper i en park och på en innergård, strandäng och torräng på tak och biotoper för insekter. Vi arbetade även med att införa vilda växter på levande väggar och undersökte levande väggars potential i Skandinavien. Jag har också jobbat med att undersöka hur stadsträd påverkas av tillförsel av dagvatten från gator och tak och vattenupptag i urbana träd, urbana ekosystemtjänster, rotinträngningar i ledningar och metallupptag, ersätta natursand med krossade material m.m. För mer utförlig presentation se min engelska sida.
