Sérgio R. Filipe serves as an Associate Professor with Tenure at NOVA University Lisbon's Faculty of Science and Technology, where he leads the Bacterial Cell Surfaces Lab from office 212. His research centers on bacterial cell surface dynamics, particularly how peptidoglycan structure and metabolism influence host immune recognition in Gram-positive pathogens.
His laboratory investigates four fundamental questions regarding peptidoglycan-host interactions: (1) how composition affects immune recognition, (2) how cell division metabolism alters detection, (3) whether surface polysaccharides interfere with recognition, and (4) alternative bacterial evasion strategies. Using Staphylococcus aureus and Streptococcus pneumoniae as primary models, his work integrates molecular microbiology, cell biology, and immunology to dissect cell wall synthesis, modification, and turnover during infection.
Analysis of his 15 most recent publications reveals consistent focus on peptidoglycan cross-linking mechanisms, cell division processes, and immune evasion tactics. His research frequently employs advanced imaging techniques and genetic approaches, with significant contributions to understanding teichoic acid functions, peptidoglycan hydrolase regulation, and bacterial surface remodeling during host-pathogen conflicts.
Professor Filipe actively mentors graduate students and maintains extensive international collaborations, particularly with M.G. Pinho's group. His laboratory develops specialized tools like eHooke for bacterial cell cycle analysis and continues to explore therapeutic implications of cell wall biology for antimicrobial development.
