'Der Forscher' (researcher) belongs to a word family: the verb is 'forschen' (to research), and the activity or field is 'die Forschung' (research). The ending '-er' refers to the male person who performs the activity.
Sie forscht an neuen Medikamenten gegen Krebs.
She is researching new drugs against cancer.
The verb 'forschen' (to research) is used with the preposition 'an' and the dative to name the research topic. A researcher researches something: 'an etwas forschen'.
Der Forscher forscht seit Jahren an den Ursachen der Krankheit.
The researcher has been researching the causes of the disease for years.
'Forscher' (researcher) is often the subject of verbs that express a discovery or finding, e.g. 'Forscher entdecken' (researchers discover), 'Forscher finden heraus' (researchers find out), or 'Forscher warnen vor' (researchers warn about).
Forscher haben herausgefunden, dass regelmäßige Bewegung das Gedächtnis verbessert.
Researchers have found out that regular exercise improves memory.
expert
'der Experte' and 'der Forscher' can both refer to people with a lot of knowledge in a field. The difference lies in the activity. An 'Experte' knows a subject especially well and can advise, assess, or explain. A 'Forscher' works scientifically and looks for new findings. Learners may confuse the words because researchers are often experts too. But not every expert does research, and not every researcher is referred to as an expert in conversation. For advice and specialist knowledge, 'Experte' fits; for scientific work, 'Forscher' fits.
