Hatshepsut
One ruler who made significant contributions to the expansion of Karnak was the female Pharoah Hatshepsut. The statue in the picture above depicts Hatshepsut in a "devotional attitude" (The Metropolitan Museum of Art). While this statue wasn't displayed in Karnak, instead at her temple in Deir el-Bahri, the article "The New Kingdom Begins in Egypt" writes that she "added two grand obelisks at the entrance" (Steiger). It also states that she built the Red Chapel, which was "a shrine that housed the sacred barque, a boat that carried the deceased kings on their journey to the afterlife" (Steiger). Since this boat is what carried Amun-Re "on his nightly journey from the west at sundown to the east, where he would rise each morning" (Steiger), this was a significant religious contribution to Karnak.
