This fellowship program is supported by the Gorgas Memorial Institute to facilitate the development of linkages between scientists from Panama, nations of Central America and the Caribbean Islands, and the United States through the award of short-term travel grants for young investigators from these regions. The program is intended to allow young scientists the opportunity to acquire new techniques or develop new approaches for the study and control of tropical diseases, and to initiate collaborative studies. Applicants should have Ph.D. or M.D. level training in a relevant field and be no more than 40 years of age, although exceptional cases may be considered. Applicants must be a citizen or permanent resident of one of the countries in the above-mentioned regions. Fellowships will generally not exceed $5,000 to cover the total costs of round-trip travel, housing and supplies for a project of no more than three months' duration.
