Introduction
Throughout my training in the field of research of natural products, the development of various interdisciplinary projects has allowed me to acquire the necessary knowledge for my personal and work growth.
My objectives are among others to apply all this knowledge for the development of strategies and verification of them with an important social impact in the fields of pharmaceutical and preclinical research, which are also the basis for the establishment of future drugs or alternative treatment options based mainly in medicinal plants.
