Mahidol University Profile 2026: Medicine, Public Health and Life Sciences for International Students

Mahidol University admits approximately 3,500 international students annually across its undergraduate and graduate programs, making it the most internationally diverse public university in Thailand by absolute numbers. This figure, drawn from the university’s 2025 international affairs report, places Mahidol ahead of Chulalongkorn University (roughly 2,800 international students) and Thammasat University (roughly 2,100). But the scale is only part of the story. Mahidol’s international programs in medicine, public health, and life sciences have become a distinct pathway for students from Southeast Asia, South Asia, and increasingly Africa and the Middle East who seek a globally recognised education at a fraction of Western tuition costs. The university’s Faculty of Medicine Siriraj Hospital, founded in 1890 as Thailand’s first medical school, now hosts over 600 international students across its English-taught MD and graduate programs. Meanwhile, the Faculty of Public Health and the Faculty of Science have expanded their English-medium offerings to meet growing demand. This profile examines Mahidol University’s international programs, tuition structures, campus life, and strategic positioning for 2026 and beyond.

Medicine and Clinical Sciences at Mahidol

Mahidol University’s reputation in medicine is anchored by the Faculty of Medicine Siriraj Hospital, which consistently ranks among the top medical schools in Southeast Asia. For international students, the key program is the Doctor of Medicine (MD) program taught entirely in English.

The International MD Program

The MD program at Siriraj accepts approximately 30-40 international students per year through a competitive selection process. The six-year curriculum follows a systems-based integrated approach, with the first two years focused on preclinical sciences and the remaining four years on clinical rotations at Siriraj Hospital, one of Thailand’s largest tertiary care centres with 2,200 beds. Tuition for the international MD program is THB 1,200,000 per year (approximately USD 34,300), covering laboratory fees, clinical materials, and health insurance. This is roughly one-tenth the cost of comparable MD programs in the United States or Australia. The program requires proof of English proficiency (IELTS 7.0 or TOEFL iBT 100) and completion of prerequisite science courses. Admission is for the August intake only, with applications closing in January of the same year. The program is accredited by the Medical Council of Thailand and recognised by the World Health Organization’s World Directory of Medical Schools.

The Master of Science in Medical Sciences (International Program) is a two-year research-oriented degree costing THB 150,000 per year (approximately USD 4,300). Students can specialise in fields such as molecular medicine, clinical epidemiology, or medical genetics. The PhD in Medical Sciences, also English-taught, costs THB 120,000 per year (approximately USD 3,400) and requires a master’s degree in a related field. Both programs are housed within the Faculty of Medicine Siriraj Hospital’s research institute, which publishes over 1,500 peer-reviewed papers annually. International students in these programs benefit from access to Siriraj’s biobank, genomics laboratory, and clinical trial units.

Clinical Training and Hospital Affiliations

Clinical training for international medical students occurs primarily at Siriraj Hospital in Bangkok. However, the Faculty of Medicine also operates affiliated teaching hospitals, including the Ramathibodi Hospital (Faculty of Medicine Ramathibodi) and the Golden Jubilee Medical Center in Salaya. International students may rotate through these sites during their clinical years. The university’s hospital network collectively handles over 3 million outpatient visits per year, providing students with exposure to a broad range of pathologies, including tropical diseases uncommon in Western settings. For international students planning to practise medicine outside Thailand, the MD program includes preparation for the USMLE (United States Medical Licensing Examination) and the PLAB (Professional and Linguistic Assessments Board) for the United Kingdom. Approximately 40% of international MD graduates from Mahidol pursue residency training abroad, according to the 2025 graduate survey.

Public Health and Life Sciences

Mahidol University’s strength in public health and life sciences is rooted in its historical mission. Founded as a medical school, the university expanded into allied health sciences in the 1960s and now operates the largest Faculty of Public Health in Thailand.
