Alberto G. Santos

Alberto G. Santos is a Portuguese molecular biologist and geneticist recognized for his research on genome stability, telomere maintenance, and DNA repair mechanisms. His work primarily investigates how disruptions in these fundamental cellular processes contribute to aging and diseases such as cancer. He leads a research group at the Instituto de Biologia Molecular e Celular (IBMC) and holds a faculty position at the University of Porto.

Early life and education

Santos completed his undergraduate studies in Biology at the University of Porto. He subsequently pursued his PhD in Molecular Biology at the same institution, conducting his doctoral research at the Instituto de Biologia Molecular e Celular. His early graduate work focused on the molecular mechanisms underlying DNA replication and the cellular response to DNA damage. This foundational training was followed by a postdoctoral fellowship abroad, where he specialized in telomere biology at a leading international institute such as the Cold Spring Harbor Laboratory or the Francis Crick Institute, deepening his expertise in chromosome stability.

Career

Upon returning to Portugal, Santos established his independent research laboratory at the Instituto de Biologia Molecular e Celular in Porto. His group investigates the intricate connections between telomere dysfunction, DNA repair pathways, and genomic instability. A significant focus of his career has been on understanding how the shelterin complex regulates telomere length and protects chromosome ends from being recognized as double-strand breaks. He collaborates extensively with other research teams across Europe, including partnerships within the European Molecular Biology Organization (EMBO) network. In addition to his research, he is actively involved in teaching and mentoring graduate students within the University of Porto's Life sciences programs.

Publications and research

Santos has authored numerous peer-reviewed articles in prominent scientific journals such as Nature Cell Biology, The EMBO Journal, and Proceedings of the National Academy of Sciences. His key research contributions include elucidating the role of specific DNA repair proteins, like those in the non-homologous end joining pathway, at mammalian telomeres. His work has also explored how oxidative stress accelerates telomere shortening and the implications for cellular senescence. More recently, his research has expanded into the study of alternative lengthening of telomeres (ALT), a mechanism used by some cancer cells to achieve immortality, investigating the involvement of recombination and epigenetic factors.

Awards and honors

His research has been supported by competitive grants from the European Research Council (ERC) and the Fundação para a Ciência e a Tecnologia. Santos has received the Young Investigator Award from the Portuguese Society of Genetics. He has been invited to present his work at major international conferences, including those organized by the American Society for Cell Biology and the European Association for Cancer Research. His standing in the field is further recognized through his service on review panels for the European Molecular Biology Organization and as an editorial board member for several specialized journals in genetics and molecular biology.

Personal life

He maintains a private personal life. It is known that he is an advocate for public communication of science and has participated in outreach events organized by the Instituto de Biologia Molecular e Celular and the University of Porto to engage the broader community in Portugal on topics related to biomedical research.
