Arbetsbeskrivning: Arbetet omfattar forskning, handledning av studenter på alla nivåer och post-doktorer, undervisning på jägmästarprogrammet, samt interna och externa akademiska uppdrag (till exempel ledamot i nämnder, opponent, och granskare av forskningsansökningar samt vetenskapliga artiklar). Forskningsarbetet bedrivs huvudsakligen i fält och interdisciplinärt i samarbeten med jägmästare, växtfysiologer och markforskare. Forskningsområdet omfattar samspelet mellan marken, mikroorganismerna, träden och andra växter i boreala skogsekosystem. Särskild tyngd ges markmikroorganismerna (inklusive mykorrhizasvamparna) deras artsammansättning och fysiologi, deras förråd av näringsämnen och vad naturliga såväl som experimentellt introducerade variationer av dessa egenskaper betyder för näringsomsättning och förluster.
