Jag är i grunden mark/växt agronom, och har sedan specialiserat mig inom markkemi. Jag har främst arbetat med att förstå hur inorganisk fosfor beter sig i jordbruksmark, och hur vi kan använda den kunskapen för att förbättra gödslingsrekommendationer.
Jag ansvarar för modulen i markemi i kursen "Marken som växtplats 3", en del av landskapsarkitektprogrammet.
