"This trip is thrilling to me because we will enter the tropics from the south instead of the north, as we travel from Buenos Aires through Argentina’s own “Mesopotamia” (Entre Rios), Corrientes and into Missiones, our final destination." ~Professor Robert Raguso

Robert Raguso, Professor of Neurobiology and Behavior, has spent most of his life tracking moths, sniffing flowers and chasing sunsets. His childhood fascination for natural history kindled a lifelong desire to travel, an enduring love for Latin America and a fulfilling career as a scientist and educator. His educational path began with undergraduate studies of butterflies (Yale), a PhD on the evolution of floral scent (Michigan), postdoctoral research on insect olfaction (Arizona) and 8 years as a junior faculty member (South Carolina), before moving to Cornell in 2007. Raguso’s expertise is in Chemical Ecology, the study of how fragrances, toxins and pheromones mediate complex biological phenomena, which he promotes globally in workshops and symposia. He speaks Spanish fluently, enjoys music, cooking and photography, travels widely in South America, and has tour guiding experience on the Peruvian Amazon, Andean Ecuador and the Galapagos Islands. Professor Raguso's course Health, Wealth, & The Divine: Biodiversity & The Human Quest debuts at CAU Summer 2026. With Robert’s guidance, your journey through Argentina becomes a sustained act of discovery—one that frames wetlands and rainforest as interconnected systems shaped by deep ecological forces.

The program ranges from moderately active to very active, depending on chosen activities. Travel is by jet aircraft, and private motor coaches or vans. The itinerary offers an in-depth look at Argentina’s culture, and natural history. Daily guided excursions include half-day and full-day options such as walking, biking, boating and horseback riding. Walks typically range from one to three miles over uneven terrain, with longer distances optional. Participation is optional, except when traveling to the next destination. Some buildings may lack elevators, and steps without handrails may be encountered. There will be three long drives in northeastern Argentina, each about four and a half hours on paved and unpaved roads. Any physical condition requiring special attention, diet, or treatment must be reported in advance. All reasonable efforts will be made to accommodate special needs, but medical services are generally not at U.S. standards. Given the remote locations, flexibility is essential as we navigate schedules, food, weather, wind, and dust.

Start your journey early with an exploration of Argentina’s cosmopolitan capital city Buenos Aires. Buenos Aires welcomes you with European elegance and Latin flair, where grand boulevards, Belle Époque architecture, and leafy parks evoke the charm of Paris with a distinctly Argentine soul. Immerse yourself in its rich cultural life — world-class museums, private art galleries, and the magnificent Teatro Colón await discovery. Visit neighborhoods not included on the main program and spend an afternoon immersed in Argentina’s delicious culinary traditions. Download more info about the Pre-Trip Extension
