Your sentence is incomplete. A natural, grammatically correct continuation depends on the topic, but here are some good options:
🧠 General completion
“In recent years, intensive research has been conducted in this field.”
🔬 More formal (academic style)
“In recent years, intensive research has been carried out to better understand this phenomenon.”
🧬 If referring to science/medicine
“In recent years, intensive research has been conducted to explore new treatment options and underlying mechanisms.”
🌍 If referring to technology
“In recent years, intensive research has been focused on improving efficiency and developing new technologies.”
If you tell me the topic (medicine, AI, environment, etc.), I can complete it in a more specific and powerful way.
