Christoph Keller’s interesses kunnen worden onderverdeeld in drie gebieden: zonne-energie fysica, exoplanetaire systemen en instrumentatie in het algemeen. In zonne-energie fysica maakt Keller gebruik van waarnemingen van de Zon in gepolariseerd licht om meer over het magnetisch veld te leren. Gepolariseerd licht wordt ook gebruikt om exoplaneten en andere lichamen die in een baan rond onze zon cirkelen te karakteriseren. De polarimetrie technologie die is ontwikkeld voor astronomische doeleinden wordt dan ook gebruikt om geavanceerde instrumenten te ontwikkelen die het op afstand meten van aerosolen in de atmosfeer van de Aarde en biomedische analyses mogelijk maken.
