Profile picture of M. (Maryory) Galvis Pedraza, MSc


I am developing jointly with my supervisor's team research about how exposure to oxidative stress develops mitochondrial failure in severely ill patients and how this is related to long-term outcomes. Previously, I worked as an epidemiologist at the Ministry of Health in Colombia, over the consolidation, synthesis, and analysis of pharmacoepidemiological information related to the immunization process against COVID-19; as well as research activities during the pandemic. I was an instructor at University ICESI in Cali, Colombia, teaching physician students the fundamentals statements in epidemiology. For almost three years, I worked in prenatal and leukemic state diagnoses by reading the karyotype using the cytogenetic techniques for reading G bands. I have training in lymphocyte culture from bone marrow, peripheral blood and amniotic cell culture. I participated in the diagnosis issue and the correlation of results with the patient's pathology. I have experience in the clinical laboratory on quality assurance and maintenance, chemistry, hematology, immunology, coagulation, and immunohematology regarding the analysis of human samples. My first work was as a microbiology analyst in areas of bacteriology, parasitology, and mycology: analysing raw water, water indifferent stations of the disinfection process, water supply network, pool water, stagnant water.
