Sciences Informatiques, Université de Nice-Sophia Antipolis,
France. Her main research interest is Quantitative Finance, with
special emphasis on portfolio selection and risk measurement. She
has published extensively in Academic journals, including the
Journal of Finance and Applied Mathematical Finance.
WALTER VECCHIATO is Head of Risk Management and Research
at Veneto Banca in Montebelluna Treviso, Italy. Previously he was
Head of Credit Derivatives Analysis at Banca Intesa in Milan,
Italy. He was also Professor of Applied Statistics in University of
Pavia, Italy and he was Visiting Researcher in Financial
Econometrics at University of California at San Diego, La Jolla. He
enhanced his research with the presence of Nobel Economic Sciences
2003 award winner Professor Robert F. Engle. He has written and
