Sohan Jheeta is an independent researcher and the Chairman of the Network of Researchers on Horizontal Gene Transfer and Last Universal Common Ancestor (NoR HGT & LUCA) as an interest lie in to understand the origin of life on Earth and life elsewhere in the Universe. Dr. Sohan’s research could be described as frontier science delving both into the areas of space science and prebiotic chemistry; the former maintains that some of the molecules which collaborated in the formation of life may have been made in the vastness of space and delivered onto the surface of the early Earth ~4.3 billion years ago; whereas prebiotic chemistry contends that life’s molecules originated solely on Earth. More importantly, in relation to NoR HGT & LUCA, he is heavily involved in the promotion of the importance of horizontal gene transfer during the period of the last universal common (or cellular) ancestor, as he believe this may hold clues to the understanding of the reorganization of genetics pertaining to the emergence of the three domains (Archaea, Bacteria and Eukarya) of life and also in the better understanding of the pre-RNA chemistry.

Dr. Areg Mickaelian (1962) is Leading Scientist, Head of Research Department and the Director at Byurakan Astrophysical Observatory (BAO, Armenia), Director of IAU South West and Central Asian Regional Office of Astronomy for Development (SWCA ROAD), Acting President of Armenian Astronomical Society (ArAS), Project Manager of Armenian Virtual Observatory (ArVO) and Director of Byurakan International Summer Schools (BISS). He is the Vice-Chair of Euro-Asian Astronomical Society (EAAS), Executive Committee member of International Virtual Observatory Alliance (IVOA) and International Planetary Data Alliance (IPDA). In 1997-2019 he has worked in the scientific centres of France, Germany, Italy and USA. His research relates to astronomical surveys, active galaxies, X-ray, IR and radio sources. He has revealed 1100 blue stellar objects, ~300 IR stars and ~1200 IR galaxies, among which he has discovered new ULIRGs and active galaxies. He has identified some 6000 X-ray sources. He has discovered the most powerful IR galaxies showing IR/opt flux ratios up to 1000 and higher. In 1999, he has founded ArAS. He has accomplished the Digitized First Byurakan Survey (DFBS). In 2005, he has created ArVO. He is author of some 260 research papers, 14 electronic catalogues, a number of books and numerous popular articles. He has edited many books, including the Proceedings of a number of meetings, published by Cambridge Univ. Press, ASP Conf. Series and other publishing companies. He is member of IAU, EAS, EAAS, AAS, ASP, ArAS, and editorial boards of 5 scientific journals.
