Mine vitenskapelige interesser omfatter det geokjemiske oppførselen til radionuklider og medforurensere i overflate- og undergrunnsmiljøer, med tilleggsoverinteresse for analytisk metodikk for bestemmelse av radionuklider. 

Med ekspertise innen avanserte analytiske, radioanalytiske og spektroskopiske teknikker for å løse utfordringer innen radioaktivitet i miljø og radiokjemi, studerer jeg for tiden forvitringsatferd, geokjemiske egenskaper og reaktivitet, samt optimale lagringsstrategier for avgangsbergarter fra alunskifer og tilhørende områder forurenset av surt avrenningsvann (RadoNorm og earthresQue prosjektene).

Som del av Centre for Environmental Radioactivity har jeg bidratt til prosjekter som undersøker biodistribusjon av uran i modellorganismer (C. elegans-nematoder og Daphnia magna-ferskvannskrepsdyr), karakterisering av kjernefysiske brenselpartikler i forurenset jord og sedimenter fra eksklusjonssonene i Tsjernobyl og Fukushima, samt optimalisering av analytiske metoder for måling av Ra-226, Sr-90 og Cs-135 ved induktivt koblet plasma massespektrometri (ICP-MS). I tidligere år har jeg også gjennomført mekanistiske studier av oppløsning av uranmineraler i et forurenset undergrunnsmiljø (UC Merced), undersøkt interaksjoner mellom uran og radium med leirmineraler i en gruvekontekst (CEA), og studert interaksjoner mellom radionuklider og medforurensere som organiske komplekserende forbindelser i sammenheng med sluttlager for radioaktivt avfall (Plymouth University).

Annet nylig arbeid inkluderer optimalisering av analytiske metoder for spesiering av selen og arsen i biologiske og planteprøver (SeGris- og SafeKelp-prosjektene), og et pågående samarbeid om vurdering av mikrobiell aktivitet i jord under varierende salinitetsforhold ved bruk av H-3 leucin som markør (SeaSoilAdapt-prosjektet).
