Igor Drobyshev

Min forskning rör sig i gränslandet mellan flera ämnen men har sin tyngdpunkt i hur boreala och tempererade skogar förändras över tid. Studier av skogsbränder – både historiska och nutida – dominerar min forskning, vilket nog hänger ihop med att vårt laboratorium i Alnarp har arbetat med brandhistoria ända sedan starten 1997. Från början låg fokus på Sverige, men sedan 2010 har vi utökat verksamheten kraftigt och arbetar nu över hela den boreala zonen på norra halvklotet – med undantag för Alaska.

Jag har alltid fascinerats av idén att samla in och använda stora, kontinentala eller till och med globala datamängder för att förstå sambanden mellan klimat och ekologiska processer. Kanske grundlades intresset redan när jag började forska i det dåvarande Sovjetunionen, där internationella kontakter var starkt begränsade. Flytten till Sverige och många år av samarbete på båda sidor av Atlanten gjorde det möjligt att förverkliga denna vision.

Idag fokuserar dendrokronologiska laboratoriet i Alnarp (www.dendrochronology.se
