A full-scale effort is underway to find him. Lawless is an assistant professor in artificial intelligence at the School of Computer Science and Statistics in Trinity College.

The 39-year-old from Wicklow was dedicating the climb and raising funds for Barretstown Children’s Hospital which treats very ill children. Close to 300 people have died climbing Everest, most of the bodies never recovered.

Trinity College Dublin shared an image of Lawless, who is married with a four-year-old daughter, on top of the mountain on their official Twitter account on Thursday morning.
