The Paraninfo Universitario UNSAAC is a beautiful monumental building located right at the main square of the City of Cusco, next to the Jesuit Church. It is a representative example of urban colonial architecture developed on top of Inca foundations, comprising a large inner courtyard surrounded by a two-story construction that contains lecture rooms of various sizes. Its theater-like auditorium, with a seating capacity of 700, is where the main sessions of LAZEN 2020 will take place. Next to the main auditorium there is a lecture room “Salón de Grados” with a seating capacity of 150, where parallel sessions will be hosted. Four additional, smaller lecture rooms will be provided for extra meetings, talks and demonstrations. The poster display area will be set up along the main hallways of the second floor and the exhibitor’s stands will be distributed on the main court. Also located inside the Paraninfo building is the university-ran Museum of Natural History, where samples of the local flora and fauna are displayed, along with geological and paleontological collections.

Located in the Central Southern Andes of Perú at 3,400 m elevation, Cusco is the third largest city in the country (430,000 inhabitants). Former capital of the Inca Empire, it is also Perú’s major tourist destination, a UNESCO World site Heritage and Archeological Capital of the Americas. Given its vicinity to major Inca sites like Machu Picchu, Sacsayhuaman and Choquequirao, the city is a perfect base-camp for the nearly two million visitors drawn to these attractions every year. Cusco’s touristic activities are by no means limited to archeological sites, as its surroundings include some of the most beautiful natural landscapes of the Peruvian Andes, with impressive sites like the Rainbow mountain, Lares Valley, Salkantay and Ausangate mountains, the fortress of Waqrapukara and Lake Humantay, all of which offer superb trekking trails and breathtaking views. Just 15 km from Cusco lies the Sacred Valley, home to the Inca sites of Moray, Pisaq and Ollantaytambo, the salt mine of Maras and many picturesque villages and colonial towns. Cusco is also known as a gateway to two of the most pristine natural reserves of the southern Amazon Jungle: Manu and Tambopata National Parks, located in the neighboring region of Madre de Dios, where wildlife can be seen as exuberant and diverse as it comes.

The beauty of Cusco is not only in its surroundings, as the city center itself is a wonderful patchwork of squares, streets, markets and temples where Inca and colonial architectural styles fuse to yield a unique urban identity. From the bohemian Barrio de San Blas -home to artists and artisans- to the Plaza de Armas; from the artful convents of San Francisco and La Merced to the stylish Museo de Arte Precolombino (MAC): from the Qoricancha or Golden Palace to the famous Hatun Rumiyoq street, the city center boasts living culture, colorful art, vibrant music and fine gastronomy. Cusco is that magical place where the ancient and the modern co-exist, where cosmopolitan meets small town flair, where all languages can be heard being spoken, where new exciting friendships are constantly started. All within walking distance, without safety concerns and with an irresistible hospitality that invites you to keep coming back.

Local Organizing Institutions

Universidad Peruana Cayetano Heredia (UPCH)


Founded in 1961 as a private and nonprofit medical university, Universidad Peruana Cayetano Heredia (UPCH) rapidly grew to become Peru’s most prestigious biomedical research institution. With four campuses in Lima, it offers graduate and undergraduate programs in medicine, dentistry, natural sciences, public health, veterinary medicine, nursing, psychology, and education. Despite its small size (under 2,000 students), it ranks second among Peruvian universities and 25th in Latin America, owing to its high standards in research and academic production. UPCH was also the first university in Peru to be accredited internationally, carrying out collaborations with leading international institutions such as the Johns Hopkins University, University of Washington, University of California San Diego, University of California Berkeley, University of Alabama at Birmingham, the London School of Tropical Medicine and Hygiene, the Prince Leopold Institute of Tropical Medicine in Belgium, and the University of Pennsylvania. Since 2017, UPCH hosts the first zebrafish laboratory of Perú, main    organizer of LAZEN 2020 and host of its practical course in Lima.

Universidad Nacional San Antonio Abad del Cusco (UNSAAC)

The Universidad Nacional San Antonio Abad Del Cusco (UNSAAC), founded in 1692, is the third oldest university in Peru and the most prestigious one in the southern region. It ranks sixth among national universities. It currently has 21,218 students attending 45 professional schools gathered in 10 faculties, including Science, Health Sciences, Law, Education, Architecture, Engineering and Administration. Recently, the university has strengthened its research activities, increasing the number of laboratories, promoting the mobility of students and professors, hosting international conferences and signing cooperation agreements with local and foreign research institutions. The city of Cusco hosts UNSAAC’s main headquarters, known as the University City of Perayoc, as well as the Paraninfo Universitario at the city main square (the main venue for LAZEN Perú 2020). Other University buildings include the mansions of Tigre Street and Arones Street where the Presidency and Graduate School are located, respectively, and Kayra Farm in the San Jerónimo district. UNSAAC co-organizes LAZEN 2020 and hosts the meeting in Cusco.

Instituto de Medicina Tropical Alexander von Humboldt (IMT-AvH)

In less than 50 years, since its foundation in 1968, the Institute for Tropical Medicine 'Alexander von Humboldt' (IMT AvH) at UPCH, has become a reference center on infectious and tropical diseases in Latin America. IMT AvH carries out research aimed at preventing and controlling tropical diseases, including clinical, diagnostic, epidemiological, socio-anthropological and ecological strategies. Work on tuberculosis, leishmaniasis, malaria, and HIV is carried out at its site in Lima and at several field stations such as Iquitos, Cuzco, and La Merced. The institute is internationally recognized for the Gorgas Course in Clinical Tropical Medicine, given jointly with the University of Alabama at Birmingham. IMT AvH co-organizes LAZEN 2020.
