Kamolwan Kularbwong was born in November 1962 in Bangkok, Thailand. She graduated from Chulalongkorn University in 1983 with a bachelor degree in public administration. After that she continued her study at the National Institute of Development Administration (NIDA) and obtained a master degree in business administration in 1985. She joined the Office of the Maritime Promotion Commission (OMPC), a government authority under the supervision of the Ministry of Transport of Thailand, in 1986 as a Transport Technical Official of the Sea Transport Economics Division. In 1990 she was transferred to work at the International Affairs Division, Office of the Permanent Secretary, Ministry of Transport of Thailand, for five years before returning to work at OMPC once again in late 1994.
As a result of the public sector reform in 2002, OMPC was dissolved and divided into two parts to merge with the Harbour Department and the Office of Transport Policy and Planning respectively. Consequently, she joined the Harbour Department which was renamed the Marine Department since then. In 2005 Kamolwan was appointed as the first Director of the International Maritime Affairs Division at the Marine Department and here she devoted her efforts as a founder of this division for ten years. Then she was transferred to the Maritime Promotion Division in 2015 and has been working as the Senior Specialist in Maritime Transport (Economics) until present.
Kamolwan specializes in international cooperation in the field of maritime transport and multimodal transport. She is interested in the role of port in changing environment and the use of disruptive technology in ports.
