- Participated in an investigation of an outbreak of EEE virus in a captive flock of endangered whooping cranes at the Patuxent Wildlife Research Center in Maryland and evaluated an experimental vaccination regime. This vaccine produced neutralizing antibodies thought to protect young cranes from this fatal disease. As a result, the vaccine was incorporated into the whooping crane propagation program at Patuxent and used on chicks produced by a flock that had been established in the wild in Florida.
- Conducted a field and laboratory investigation following an episode of unexplained deaths in 29 free-ranging horses at a remote location on the U.S. Army's White Sands Missile Range in New Mexico. Mosquitoes were collected and identified for laboratory assay. Several pathogenic arboviruses, including western equine encephalitis (WEE), and a new mosquito-borne virus were isolated. These results provided the basis for additional studies of several arboviruses pathogenic to wildlife and domestic livestock in southern New Mexico.

Relevant Volunteer Activities
- I have been the principal organizer of the Spanish Language Symposium at the American Mosquito Control Association's last 15 annual meetings. Financial support has been obtained from various sources to bring young scientists and vector control specialists from Latin America to this U.S.-based meeting. This successful symposium with simultaneous translation has generated many fruitful and productive interactions between colleagues from Latin America and their North American counterparts. I organized a major international symposium on "Current status of vector control strategies" for the Annual Meeting of the American Society of Tropical Medicine and Hygiene. I worked with the participants to prepare a refereed supplement to the Society's Journal, which was published in 1994.
- In 1989, I became a member of the Rotary Club of San Juan (Puerto Rico) and actively participate as a technical advisor to the Club's Dengue Prevention Committee. Community-based programs have been initiated in Puerto Rico with the elementary schools, the Head Start program for economically disadvantaged children, the Boy Scouts, and the Children's Museum in San Juan. I have presented and promoted the Club's dengue prevention program to Rotary Clubs in the Dominican Republic, Honduras, Panama, Colombia (Medellin, Bucaramanga, and Puerto Berrio), St. Kitts, Anguilla, Barbados, and Martinique. I was President of the Rotary Club of San Juan in 1999-2000.
- At the request of the Rotary Foundation, I served as a site visitor for major 3-H (Health, Hunger and Humanity) Projects to review project progress in Argentina and Bolivia (Chagas' Disease) and Mexico (tuberculosis). I was also a reviewer of project proposals that were subsequently funded for dengue and malaria prevention in Honduras. I am also part of an evaluation team for a malaria prevention project in Vanuatu supported by the Rotary Foundation and the Bill and Melinda Gates Foundation. The last project promotes the use of long-lasting, insecticide-treated bed nets for malaria prevention in villages throughout this South Pacific country.
