Om mig

Jag är biträdande lektor i utvecklingspsykologi vid Aging Research Center (ARC), Institutionen för neurobiologi, vårdvetenskap och samhälle (NVS) vid Karolinska Institutet. Min forskning handlar om hur kognitiva och sensoriska funktioner påverkas i högre ålder. Jag fokuserar särskilt på två områden: (1) att förstå vad som orsakar nedsatt luktsinne hos äldre och vilka konsekvenser detta kan få, och (2) att kartlägga hur lukt- och minnesfunktioner förändras över tid vid normalt åldrande och demens, samt hur dessa förändringar hänger ihop med biologiska faktorer.
Sedan januari 2023 leder jag projektet "Harmful Consequences of Smell Loss in Old Age: A Longitudinal Population-Based Study, " som finansieras av Riksbankens Jubileumsfond (2 850 000 SEK
2023–2026). I projektet använder vi data från National E-infrastructure for Aging Research (NEAR) för att undersöka möjliga samband mellan nedsatt luktsinne och tillstånd som depression, ensamhet och undernäring.
