In Memoriam – Djoko Wirjawan, 1961 – 2022

We are sad to report that Djoko Wirjawan, a Run I Ph.D. student with Texas A&M, died on April 18 in Surabaya, Indonesia. Wirjawan was a faculty member at Widya Mandala Catholic University. He worked on the now-topical subject of electron-tau universality, and as his thesis research conducted the first DZero search for chargino-neutralino production in the three lepton final state. Wirjawan was one of the first Indonesian particle physicists; after his Ph.D. he returned to Indonesia to guide the development of high energy physics.
