Ignacio Araya studied his Bachelor of Science in Astronomy and his Master of Science in Astrophysics at the Pontificia Universidad Católica de Chile (PUC) in Santiago. Then, he pursued a Ph.D. in Physics at the University of Southern California (USC) in Los Angeles, USA, under the supervision of Prof. Itzhak Bars. During that time, he worked in physics with two-time signature (2T-physics) and Brans-Dicke gravity. Later on, he was appointed as a postdoctoral fellow at Universidad Andrés Bello (UNAB) in Santiago, where he worked in AdS/CFT holography, developing a method for renormalizing holographic entanglement entropy for conformal field theories with classical gravity duals, including higher curvature gravity theories. He has also worked in cosmology, studying the effects on the early universe of primordial black hole populations as dark matter candidates. Currently, he is a member of the Instituto de Ciencias Exactas y Naturales (ICEN) at Universidad Arturo Prat (UNAP) in Iquique, and his research lines are in gravitation and cosmology, in particular in the topics of AdS/CFT holography and primordial black holes.
