Handhika S. Ramadhan, Ph.D was born in Jakarta, July 10 1983. He received his bachelor in physics from University of Indonesia in the field of theoretical physics in 2005. He obtained his PhD in theoretical cosmology from Tufts Institute of Cosmology, Tufts University at Medford, Massachussetts, USA, in 2011, under the supervision of Prof.Jose Juan Blanco-Pillado. His dissertation title is “Higher-dimensional Topological Defects in Cosmology”.

Dr.Ramadhan’s research interest is in the area of topological defects (domain walls, cosmic strings, monopoles, textures), and their roles in cosmology, nuclear and particle physics. He is also interested in the study of instantons and vacuum decay in cosmology; in particular, the non-perturbative transition (quantum tunneling) in string theory flux compactification.
