Prof. Daniele Malafarina is currently Associate Professor at the Department of Physics, Nazarbayev University, Kazakhstan. He has been working on relativistic gravitational collapse since his Ph.D. Over the past 15 years, he has published around 50 articles on collapse and black hole physics. Prof. Pankaj S. Joshi is currently Distinguished Professor & Founding Director at the International Centre for Space & Cosmology, Ahmedabad University, India.

Earlier he was Senior Professor at the Tata Institute of Fundamental Research, India. He has a decade-long experience on relativistic gravitational collapse. He was among the first to investigate naked singularities in Lemaitre-Tolman-Bondi collapse models and has written dozens of articles and two books on the subject: Global Aspects in Gravitation and Cosmology (OUP, 1993) and Gravitational Collapse and Spacetime Singularities (CUP, 2007).
