Ana Estrada-Florez, Ph.D.
Ana is from Colombia, she graduated from the University of Nariño with a BS in Biology. She became a member of the “Cytogenetics Research Group” at the University of Tolima in 2012 during her M.Sc. in biology and her research was to study the association between papillary thyroid cancer (PTC) and SNPs, previously reported in European and Asian populations.
During her Ph.D. in Biomedical Sciences at the University of Caldas, she joined Dr. Carvajal’s lab as a visiting scholar to conduct research aimed to analyzing the epidemiology of thyroid cancer in Latinos and to discover new variants associated with the risk of the disease by using GWAS and WES.
She loves to bike, hike and dive.
