Liam Kennedy sa zameriava na americké štúdie a vizuálnu kultúru, pričom jeho práca prepája kultúrnu a politickú analýzu. Skúma globálne a transatlantické vzťahy a analyzuje, ako vizuálna kultúra formuje naše chápanie mestských priestorov a medzinárodných záležitostí. Kennedyho výskum sa často zaoberá fotografiou, mestskou regeneráciou a dopadom americkej zahraničnej politiky na globálnu scénu. Jeho interdisciplinárny prístup ukazuje silu amerických štúdií ako rámca na pochopenie zložitého sveta.
