Zsolt Frei is Professor of Astrophysics at Eötvös University, Budapest. He received his MSc equivalent diploma in Physics from Eötvös (1989), and his PhD in Astrophysical Sciences from Princeton University, in 1994. He had a visiting position at Max Planck Institute for Astrophysics, Garching, Germany (1995), and a postdoc at the University of Pennsylvania (1996-98), and also spent significant time at UT and at Fermilab before returning to a tenured position at Eötvös.
At Eötvös he established the Astrophysics teaching program, published the first Hungarian language book on Cosmology (with co-author András Patkós), and started to work with PhD students so successful, that the first of them, Bence Kocsis won a Harvard University predoctoral fellowship after only two years of work. His research interests include automatic morphological classification of galaxies for large sky surveys, merger tree codes to simulate structure formation of the early universe, LIGO data analysis, and astrophysical studies of gravity-wave counterparts both for LIGO and the proposed LISA.
Zoltan Haiman, a theoretical cosmologist, is Associate Professor of Astronomy at Columbia University in New York. He has been a leader in studies of the formation of the first structures in the universe, and has published more than 100 peer-reviewed papers on this subject. Haiman is the recipient of several research grants from the US National Science Foundation (NSF) and from the National Space and Aeronautics Administration (NASA), which, over the past 10 years, total $2.6 million. In 2010, he was the recepient of the Blavatnik Award for Young Scientists by the New York Academy of Sciences.
Haiman has broad research interests in theoretical astrophysics. He has clarified the dominant role of molecular hydrogen in forming the first stars and black holes. He has spearheaded the interpretation of many recent significant Astronomical observations involving the most distant galaxies and quasars in the universe. He has recently been working on novel ways to understand the nature of the acceleration of the universe by the so-called dark energy, using a method called weak gravitational lensing. He worked with Hungarian students Zoltan Lippai to study the early history of black hole growth and mergers in
the Universe, and with Bence Kocsis to study the electromagnetic signatures of super-massive black hole mergers, which could be detected by future gravity wave experiments. He continues to work on this subject. With Kocsis and Frei, he also proposed a novel probe of finding shocks around the edges of galaxy clusters, an important yet poorly tested part of our modern cosmic structure formation paradigm. These collaborations have so far resulted in three master's diplomas at ELTE.
István Szapudi is professor of Astrophysics at IfA, Hawaii. He is a member of the Sloan Digital Sky Survey (SDSS), member of Pan-STARRS, and also member of other surveys, such as Deep2, 2dF-SDSS LRG/QSO group, and have strong ties with the Planck experiment. His work and analysis techniques contributed significantly to the first direct detection of the Dark Energy via the Integrated Sachs Wolfe effect, the first detection of baryonic oscillations, and to the measurements of cosmological parameters.
IfA is producing a large fraction of astronomical data today, and in the near future, with the emergence of Pan-STARRS, it will produce an overwhelming fraction of the total of astronomical data in the world. He has an unusually strong background in computer science, statistics, and mathematics, which, blended with the more traditional concepts of theoretical astronomy, are crucial for finding the needed interdisciplinary solutions to the pressing data problems. His broad research goals include: to create novel (statistical) analysis tools which can handle the data avalanche of the 21st century, to apply such tools to data observed at IfA, and to data available publicly, and thereby constrain cosmological theories and the origin of the universe, to develop the cosmological theories of origin, and to solve the greatest mystery of 21st century physics: Dark Matter and Dark Energy.

He has worked on the structure and reactions of nuclei far from stability, and discovered the nuclear quantum amplification phenomenon. He calculated the reaction rates for several solar nuclear reactions, which determine the solar neutrino fluxes. He showed that the synthesis of carbon and oxygen is extremely fine-tuned in the Universe, and gave constraints on the basic forces of Nature. He studied the effects of temporally varying fundamental constants on nucleosynthesis in the Universe. He has written 40 scientific papers.

His research focuses on classical solutions and their dynamics in gauge theories and gravity (topological defects, particle-like solutions, black holes and their interactions with other fields) and on quantum field theory. He develops combined numerical and analytical methods in gauge theories coupled to general relativity. He has studied higher dimensional gravity theories and was first to point out that in this framework the natural "constants" (Newton's constant, the fine structure constant) become space-time dependent. He also has important results in developing a dimensional reduction procedure and determined the Higgs potential in a geometrical way. He has important contributions in the study of magnetic monopoles.

Carlo Nicola Colacino was a postdoctoral research fellow at EIRSA. He received
his “Laurea” in Theoretical Physics (MSc degree) from the University of Rome
“La Sapienza” in 1996 and his PhD degree in Nuclear and Subnuclear Physics
from the University of Cagliari in 2001, both under the supervision of Massimo
Bianchi. He was then hired as a postdoctoral fellow by the Max-Planck-Institut for Gravitational Physics in Hanover, where he was a member of the GEO600 project under the supervision of Karsten Danzmann and in 2004 he joined as a postdoctoral scholar the University of Birmingham, where he worked on Gravitational-Wave data-analysis in the group led by Alberto Vecchio. In 2006-07 he was awarder the position of lecturer to replace some colleagues who were on sabbatical leave. In October 2007 he moved to Hungary, first to the
Theoretical Department of the Research Institute for Nuclear and Particle Physics (RMKI) to work with Péter Forgács (associated EIRSA faculty), and subsequently to Zsolt Frei's group at ELTE.

collaboration with JY Vinet's group at the Observatoire de la Cote d'Azur in on
research and development for the forthcoming LISA and LISA Pathfinder missions. He moved on to a position at INFN Pisa (email@example.com).
Simon Gallerani was a postdoctoral research fellow at EIRSA. She has received her PhD from Trieste. She was working on interpretations of observations of cosmic epochs closer to the present that have indisputably shown that the cosmic gas is in an ionized state. It is yet unclear when the phase transition from the neutral state to the ionized one started. Thus, the reionization epoch is still undeﬁned.
In the last few years, our knowledge of the reionization process has been
enormously increased mainly owing to the observation of z>6 quasars by the SDSS survey and CMB data. She proposed a semi-analytical criterion in order to constrain the IGM ionization state, starting from the measurement of the transmissivity windows extent. She now works on the interpretation of the measurement of the high-z ultra-violet background by analyzing, statistically, properties of the transmitted ﬂux in z>6 QSOs and GRBs absorption spectra. She has moved on to a position in Roma (firstname.lastname@example.org).
