Roger Torrenti
CEO
"I feel fortunate to have been in Sophia Antipolis since its early days and like many others I was inspired by the enterprising spirit that was developing here. Youthful idealism and the feeling that here in Sophia I could work at doing something special led to me creating Sigma Orionis (ex Sigma Consultants) 24 years ago, a decision and a time I've never regretted. Sigma Orionis is today a solid, highly experienced group of likeminded people who have all agreed to be active contributors, to be of service to our clients, to be ethical and honest and to enjoy doing things well. We're not a new company but we are a young company and we continue to attract outstanding people who share our confidence about where and what we are and where we are going".
Roger Torrenti graduated in 1976 from Ecole Centrale de Paris, one of the French "engineers high schools". He began his career as a research engineer at the French Atomic Energy Commission (CEA), where he developed a specialized knowledge in energy technologies. Two of his research results were patented in 1977 and 1978. He also had the opportunity to be involved in international working groups, from 1979 onwards, within the IEA (International Energy Agency) and EC projects. In 1979, he was given the management of an applied research institution linked to Ecole Nationale des Mines de Paris and the French Ministry for Industry. Its core activities concerned the use of information technologies in energy systems. There, Roger developed his specialized knowledge of the energy and IT fields (one of his research results was patented in 1981) and his international experience (he was involved in international research projects and the organization of international conferences). In 1984, Roger Torrenti founded Sigma Orionis (formerly Sigma Consultants), and he is still its CEO and main shareholder. He is often invited by national or international institutions to act as an expert in his specialized fields of technological knowledge. He has, for example, been acting (since 1990) as an evaluator or reviewer in many European Commission Programs. His passions include mountain climbing, philosophy, photography, modern art, and basketball.
