Om
Jeg er miljøingeniør med spesialisering i vannkvalitet og -behandling, med fokus på hvordan komplekse blandinger av organiske og uorganiske forurensninger beveger seg gjennom, og kan fjernes fra, naturlige og urbane vannsystemer. Min forskning omfatter drikkevannsbehandling (koagulering–flokkulering, porøse membraner og fjerning av naturlig organisk materiale), trafikkrelatert forurensning (tunnelvaskevann og avrenning fra veier), PFAS-atferd og sanering (jord–vann-separasjon, jordvasking og optimalisering av koagulering/flokkulering) og avansert/hensiktsmessig behandling av vanskelig avløpsvann som deponigjennomtrengningsvann (inkludert elektrokjemisk oksidasjon). Nylige artikler og rapporter viser: forekomsten, risikoen og behandlingsmulighetene for tunnelvaskevann og effektiviteten av sekundærbehandling (f.eks. GAC) for å redusere både kjemisk belastning og bioassay-responser; hvordan PFAS-sorpsjon kontrolleres av kornstørrelse og rester av organisk materiale, med praktiske implikasjoner for jordvasketog; og hvordan elektrokemiske prosesser kan redusere persistente organiske stoffer i utvaskingsvann fra kaldt klima på en kostnadseffektiv måte. Jeg arbeider også med naturbaserte løsninger for urbant overvann, hvor jeg kobler design, ytelsesevaluering og vedlikehold for å mainstream bruken av disse, og med å flytte feltet mot risikobasert overvåking som kombinerer målrettet analyse med effektbaserte metoder.
Forskning
Mitt hovedforskningsfokus er relatert til organisk og uorganisk forurensning i naturlige og urbane områder, og hvordan forurensning påvirker våre vannressurser, hvilke risikoer som er forbundet med dette og hvordan de kan reduseres. Kjemikalier finnes overalt, og nye kjemikalier utvikles og introduseres i rekordfart. Mange kjemikalier er designet for å ha kraftige effekter, for eksempel legemidler, herbicider, pesticider, myknere osv., som finnes i byggematerialer, maling, kjøretøy, klær og mye mer.
Mange av disse kjemikaliene havner til slutt i miljøet, hvor de kan transporteres for eksempel med vann eller luft, og kan gjennomgå en transformasjon til ukjente produkter, for eksempel ved UV-stråling og biologiske prosesser. I en slik situasjon blir analyse og risikovurdering en utfordring, siden det er ukjent hvilke kjemikalier som kan være til stede og hvor giftige de kan være, da de vil virke sammen som blandinger og ikke som individuelle forbindelser. Kjemikalier kan være til stede i konsentrasjoner under deteksjonsgrensen, men likevel bidra til giftige effekter. Dette krever effektbaserte metoder for risikobasert vannkvalitetsanalyse. Kjemikalier som PFAS er spesielt bekymringsfulle, fordi de kan karakteriseres som persistente, mobile og giftige (PMT).
Klimaendringene forventes å forsterke forurensningsrelaterte utfordringer, for eksempel på grunn av økt hyppighet og intensitet av ekstreme værhendelser, som kan mobilisere forurensning fra områder som ellers ble ansett som trygge, for eksempel på grunn av flom, mobilisering fra urbane overflater, industriområder eller jordbruksarealer og overløp fra kloakksystemer. Selv om kontroll av forurensende stoffer ved kilden kan vise seg å være den mest effektive tilnærmingen, vil kjemikalier bli sluppet ut, og det vil være behov for tekniske løsninger for håndtering av både diffuse og punktkilder.
NATURE THRIVES - NATURE-based urban water Transitions for Healthy, Resilient, InclusiVE regional Scapes
Implementation of Nature-Based Solutions for urban water management: towards standardization, well tested and monitored solutions and positive communication of the successful transition.
INFILTRATE: Roadside swale/buffer strip infiltration systems for treatment of road runoff in Nordic countries
The main purpose of this project is to increase the knowledge about and produce guidance on infiltration solutions used for pollution control in road runoff. This includes water quality measurements and environmental risk assessment.
Treatment of wash water from road tunnels
Tunnel wash water is highly contaminated water containing high concentrations of pollutants like trace metals, PAH, PFAS, BTH, benzotriazoles, bisphenols, microplastics etc. The project investigates future treatment and management strategies.

Min undervisningsmetode er basert på en bevisst overgang fra tradisjonell forelesningsbasert undervisning til en forskningsbasert, undersøkende modell som fremmer dyp læring, faglig kompetanse og studenters eierskap. Med utgangspunkt i prinsippene fra PBL, TBL og CDIO utformer jeg læringsmiljøer hvor studentene arbeider med autentiske datasett, åpne ingeniørproblemer og laboratorieopplevelser som gjenspeiler kompleksiteten og usikkerheten i virkelige utfordringer knyttet til vann og avløpsvann. Sentralt i min praksis står formativ vurdering, inspirert av Wiliams evidensbaserte rammeverk, som skaper kontinuerlige tilbakemeldingssløyfer som klargjør forventninger, avslører læringsfremgang og veileder justeringer i sanntid for både studenter og lærere. Gjennom strukturert teamarbeid, refleksjonsrutiner og integrering av tekniske, analytiske og kommunikative ferdigheter støtter jeg studentene i å utvikle ikke bare konseptuell forståelse, men også den ingeniørmessige tankegangen som er nødvendig for profesjonell praksis, som kritisk tenkning, beslutningstaking under usikkerhet og evnen til å begrunne og forsvare løsninger.
