Kagome lattices have emerged as one of the most fertile platforms in modern condensed-matter physics, owing to their unique intertwining of topology, electronic correlations, magnetism, and flat-band physics. Over the past years, my research program has focused on uncovering the microscopic mechanisms governing superconductivity, magnetism and symmetry-breaking electronic states in kagome materials, using local magnetic probes as a unifying experimental framework. In this talk, I will present a coherent body of experimental advances that provide microscopic insight into superconductivity, normal-state magnetic responses, and charge order in kagome systems across multiple material families. Our central tool is muon-spin rotation (µSR), employed in combination with depth-resolved measurements, chemical substitution, and extreme tuning parameters including hydrostatic pressure, uniaxial stress, ultra-low temperatures, and high magnetic fields. These studies are complemented by magnetotransport and X-ray diffraction measurements under comparable extreme conditions, enabling a unified view of electronic and magnetic responses. The key results of this work include: Time-Reversal Symmetry-Breaking and Unconventional Pairing in AV₃Sb₅ (A=K, Rb, Cs) and record-High Charge Order, Emergent Magnetism, and a Pressure-Induced Superconducting Dome in Ru-based Kagome Metals: RRu₃Si₂ (R=La, Y, Ce).
