I completed my PhD in Chemistry from the National University of Colombia in Bogota Colombia in 2011 where I worked on elucidate protein phosphorylation profiles in response to growth factors in cancer invasion. I have gained significant expertise in cell culture, RNAi and quantitative proteomics.

Since 2011, I did take up a research position at the Malaria Vaccine and Drug Development Center (MVDC) in Cali, Colombia, investigating the molecular biology of malaria disease. I have gained comprehensive scientific expertise, critical thinking skills, and developed strong leadership: project management, and communication skills.

I have strong theoretical knowledge and technical expertise in Molecular and Cellular Biology, Immunology, and Microbiology. This includes, ELISA, western blotting, proteomics, cell metabolic assays, mammalian cell culture, cell migration and invasion assays, RNAi, bacterial culture, PCR, RT-qPCR, DNA and RNA isolation, microarrays and RNA sequencing analysis, bioinformatics tools management.  I also have experience in animal model design, handling, and transgenic parasite production.

Funded by National Institute of Allergy and Infectious Diseases (NIAID).                                   2015-2016

Role: I was in charge of the production of a transmission blocking vaccine candidate, the Pvs48/45 protein, using codon harmonization approach in an E.coli host.

  • Evaluation of the loop mediated isothermal DNA amplification (LAMP) for malaria in a Plasmodium vivax endemic setting.

Funded by the Foundation for Innovative New Diagnostics (FIND).                                            2013-2014

Role: I was in charge of the experimental design and malaria diagnosis using loop mediated isothermal amplification and qPCR. During this project I have gained experience conducting field trials in malaria endemic regions as well as overall project coordination.

  • Development of Plasmodium vivax immunization and sporozoite challenge model for human volunteers.

Funded by National Heart, Lung, and Blood Institute (NHLBI).                                                     2011-2015

Role: I was in charge of the malaria diagnosis using molecular tools. I have gained significant experience in clinical vaccine development, clinical trials, good clinical practices and databases for clinical research.
