Dr. Retamal conducted his undergraduate thesis studying the relationship of the stromal microenvironment in bone metastasis of breast cancer. He then worked for 7 years as a research assistant on projects aimed at elucidating the signals and trafficking of receptors from the LRP family. In his doctoral studies, he delved into the study of the crosslinking of endocytic and exocytic pathways in polarized epithelial cells. Currently, he uses his knowledge to study intracellular receptor trafficking and its relationship with pathologies in polarized cells. For example: EGFR in cancer, NMDAR in neurodegeneration, CXCR5 in chemoresistance, and TLRs in the epithelium-microbiota interaction

Dr. Claudio Retamal completed his biochemistry studies at the University of Chile and then worked as a research assistant on cellular biology projects. He then pursued his doctorate at the Pontificia Universidad Católica de Chile. Since joining the University of San Sebastian, he has sought to establish a research line focusing on intracellular protein trafficking, particularly in polarized cells, and its relationship with physiology and pathophysiology in various tissues

Dr. Claudio Retamal teaches undergraduate courses in cell biology and biochemistry, where he strives to foster a passion for research among students in their early years. In postgraduate studies, he teaches courses in Cell Biology and Biomedicine, where he explores the relationship between intracellular receptor trafficking and pathologies in epithelial cells. Additionally, he teaches in the advanced cellular microscopy course, where he shares his experience and knowledge in visualizing subcellular processes
