Forskningsinteresser
Johansen leder det tverrfaglige Corpore Sano senteret som driver grunnforskning i spenningsfeltet mellom grunnleggende informatikk, idrettsvitenskap, medisin, helseteknologi og ernæringsvitenskap. Han er spesielt interessert i grunnleggende programvareløsninger som muliggjør sikker og feilfri databehandling i heterogene distribuerte systemer som inkluderer fra lette "Internet of Things" enheter og mobiltelefoner, til bakenforliggende stor-skala skyløsninger.
