Allan Xavier Pernudy Ubau is a professor of hematology. Until 2018 he was teaching at the National Autonomous University of Nicaragua (UNAN), and was the director of the laboratory for molecular biology at the Polytechnic Institute of Health, UNAN-Managua. He started his career at UNAN where he earned his BSc degree in clinical bio-analysis (2002). Then he obtained an MSc in hematology, from the University of Costa Rica (2008). He expanded his academic education in Germany, studying leukemogenesis, and earned his PhD from the University Medical Center Hamburg-Eppendorf (UKE), in 2013. Both his Master and PhD studies were financed by scholarships (German Academic Exchange Service - DAAD). Back home, he established the first molecular biology laboratory on leukaemia and anemia diagnosis at UNAN-Managua. He started a successful collaboration with an international pharmaceutical company resulting in free-treatment access for patients in Nicaragua. He is a member of the Caribbean Network of Researchers on Sickle Cell Disease and Thalassemia, and the recipient of awards and honours including a three-month Visitor Training Program, with the American Society of Hematology (2015).

Dr. (Prof.) Oswalt R. Jiménez is a scientist in agrobiotechnology, seed technology, and plant breeding, graduated (MSc, Ph.D.) from the University of Helsinki, Finland. During his career, he has held important work positions at universities and government institutions devoted to agriculture. He has leaded research teams at the national level in alliance with prestigious international agencies for cooperation and development. His work is focused on the use of local plant genetic resources in plant breeding programs aided by biotechnological tools, under conventional and participatory approaches. He has promoted the use of molecular markers to preserve the genetic purity of commercially released plant varieties and the study of local microbiota with high potential for crop management and multiple disease control in several important crops. Additionally, he has supervised the research projects of undergraduate, Master's and Doctoral students from National Agrarian University (NI), University of Central America (NI), Zamorano University (HN), University of Costa Rica (CR) and University of Helsinki (FI).
