Nye tider på au.dk

Aarhus Universitets hjemmeside er ved at blive redesignet. Design og indhold vil derfor ændre sig, og du vil kunne opleve, at indhold ikke ligger, hvor det plejer.

Vi håber, at eventuelle gener opvejes af glæden ved en ny hjemmeside med større sammenhæng på tværs og en mere enkel brugeroplevelse.

Giv din feedback

Hvorfor roder vi?

I den kommende tid vil universitetets hjemme­side være en blanding af sider i nyt og gammelt design.

I foråret 2011 blev AU's ni hovedområder til fire og 55 institutter til 26 for at samle organisationen og styrke tværfagligheden. På samme måde er vi nu ved at lægge hele hjemmesiden om, så der bliver bedre sammenhæng i indhold og design.

Tag smutvejen

Under knappen GENVEJE øverst til højre finder du links til det mest brugte indhold på hjemmesiden samt til to nye universer til medarbejdere og studerende.

Hvor finder jeg det?

Få et overblik over indholdet på hjemmesiden med de nye megadropdowns. De åbner sig, når du kører musen hen over navigationen i toppen.
