Lin was a leading public health advocate, and one of Taiwan's best-known toxicologists. He gained a reputation as a public health expert and
science communicator during a series of mass scares in Taiwan over health issues, including
hornet attacks,
lead poisoning and contaminated food. He regularly advised the Taiwanese Department of Health and Welfare on medical policy, food safety and potential threats to public health. Lin also conducted research into new
vaccines and their effects on human health, and established a medical service team to provide free health consultations in poorer communities. ==Death==
