Location  
RTIC is situated at the Tanaosri subdistrict, Suan Phung district, Ratchaburi province. Ratchaburi is one of the several provinces that outline Thailand with its neighboring nation, Myanmar. Further into the province is Suan Phung district that particularly delineates the Thai-Myanmar border. The Tanaosri subdistrict is located at the southern part of Suan Phung. Majority of the people who live around RTIC are Karen. As this is the case, most of the residents don’t speak the Thai language. This situation posed a great challenge in setting up research within the area. Seeing the need, the research staff had to learn the local language which led to the establishment of a better relationship with the people.
 
Land area
The total land area reserved for the RTIC covers around 6,400 square meters. This land was originally reserved for the military force located near the Thai-Myanmar. With the intercession of the Department of Forestry, the land was handed over to the Faculty of Tropical Medicine for the construction of the RTIC. As of the moment, less than 20% of the land is being occupied by the different facilities and structures of the centre.
