Tillykke til Det Tekniske Fakultets første doktor

Fredag fik Det Tekniske Fakultet sin første doktor. Sven G. Sommer blev udnævnt til doktor i teknik efter en afhandling om ammoniakfordampning.

Sven G. Sommer blev fredag den 24. maj 2013 udnævnt som doktor. Dermed bliver han den første doktor i teknik udnævnt fra Det Tekniske Fakultet på Syddansk Universitet og kan nu smykke sig med den fineste akademiske titel.

Hans afhandling om pH-værdiens påvirkning af fordampning af ammoniak til miljøet har dermed bragt videnskaben et betydeligt skridt videre.

Stor miljøpioner
Sven G. Sommer har brugt hele sin 30-årige forskerkarriere på at arbejde for en miljøvenlig dyreproduktion i Danmark, og hans arbejde har bidraget til, at dansk landbrug i dag er blandt verdens reneste.

Sven G. Sommer var en af de første, som tilbage i 80´erne gjorde opmærksom på, at landbrugets udledning af ammoniak var et stort problem for kvaliteten af vores natur. I dag ved man, at landbruget står for 90 procent af udledningen af ammoniak.
