Jag jobbar sedan januari 2017 heltid som riskanalytiker vid den nya Enheten för riskvärdering av nya växtskadegörare
Min tidigare forskning syftade till öka kunskapen om vad man kan göra för att minska de skador som skogsskadeinsekter orsakar. Jag har framförallt arbetat med snytbaggen, granbarkborren och contortabastborren (mountain pine beetle).
