<span style="background-color: rgb(255, 255, 255); text-transform: none;">Convergent plate margins are sites where collision results in contractional deformation that reshapes the lithosphere. Where continental plates converge, crustal thickening generates
topography and drives mountain building, or orogenesis. The Himalayan orogen has long served as a natural laboratory for this process, yet key questions remain regarding the magnitude, architecture, and timing of crustal deformation during orogenesis. This
talk integrates regional structural geology with isotopic and geochemical datasets to reassess how and when contractional deformation is distributed and recorded in the eastern Nepal sector of the Himalayan orogen. I then broaden the perspective to convergent
margins where oceanic plates collide with oceanic/continental plates leading to subduction and crustal recycling. To investigate deformation mechanisms at the deep subduction plate interface, this work examines exhumed fossil subduction zone rocks from the
Greek Cyclades. Together, these examples of continental collision and subduction reveal how deformation operates spatially and temporally at different scales in convergent plate margins. </span></div>
