Lea's key expertise areas are VALORANT (esports scene, GC scene, game/performance analysis) and DEI/social issues in esports (women's esports scene but also a profound understanding of DEI in esports from an academic perspective).
These are the areas in which Lea invest most of her time/research. For example, I watch all VCT games globally, which is why I'm familiar with all major storylines, regional metas/playstyles, players/teams etc.
