Interests

My current research interests focus on computational statistics and stochastic modeling at different scales:

Molecular scale: Implementation and development of new techniques of statistical analysis and molecular information modeling in order to generate novel and useful tools for the synthesis of compounds with high probability of relevant biological activity. This project involves the use of data analysis techniques (multivariate statistics, data mining, machine learning and data science) to study and characterize large databases consisting of physical, chemical and topological descriptors of compounds and to explore relationships, correlations and dependences between structures, properties and biological activities of the compounds. Collaboration with Javier Ramirez, Pau Arroyo Mañez and Victoria Richmond (UMYMFOR, Department of Organic Chemistry, FCEyN, UBA).

Population scale: Stochastic modeling of dynamical systems applied to population dynamics and epidemiology: development of mathematical models of vector borne-diseases of national and international sanitary importance. I have been studying vector-pathogen-host systems from an integral and interdisciplinary point of view, incorporating in the models not only the life cycle of vectors and hosts, but also those environmental factors and variables that affect them, in order to develop guidance, prevention and control tools, with application in human, veterinary and agricultural health. I have been modeling the spatio-temporal dynamics of disease vectors such as Aedes aegypti, Dalbulus maidis and Peregrinus maidis, and the spatio-temporal dynamics of some of the diseases they transmit such as Dengue and Yellow Fever (human diseases transmitted by the mosquito Aedes aegypti) and Corn Stunt Spiroplasma (Maize disease transmitted by the leafhopper Dalbulus maidis). Collaboration with H. G. Solari (IFIBA-DF, FCEyN, UBA), M. Giménez Pecci (INTA-Córdoba) and M. Natiello (Lund University, Sweden).
