Forskning och undervisning

Jag undervisar i ekologi och miljövård på ett flertal av SLU:s program och kurser. Jag är också studierektor för grundutbildningen på institutionen för ekologi och SLU:s representant i samarbetet Euroleague for life science (ELLS), ämnesområde miljövetenskap och för masterprogrammet EnvEuro.

Min forskning är inriktad mot markekologi, särskilt markdjurs ekologi i jordbruksmark och hur markorganismer påverkas av olika typer av jordbrukssystem och hur de samspelar i markens näringsväv. Dessutom är jag intresserad av hur den biologiska mångfalden ska kunna bevaras i det moderna jordbruket, både i marken och i landskapet i stort.
