About

Overview

Professor Iori obtained a BSc and a PhD in Physics from the University of Rome. Between 1993 and 1998 she was a research fellow in theoretical physics at the University of California Santa Cruz, the CEA-Saclay in Paris and the University of Barcelona.

Before joining City University London as a Professor of Economics, she worked at the University of Essex and at Kings College London. She taught courses in Financial Engineering, Corporate Finance, Investment, Financial Mathematics, Financial Derivatives and Exotic Options.

Her current research interests include: high-frequency financial time series analysis, option pricing and hedging, risk evaluation, market microstructure and complexity in economic networks. Professor Iori is principal investigator on a large grant from the EU.

Professor Iori is the leader of one of the groups in Forecasting Financial Crises (FOC), a European scientific project aimed at understanding and forecasting systemic risk and global financial instabilities.

Research

Professor Iori's current research is mostly focused on issues in market microstructure, financial stability and systemic risk. She has been doing theoretical, empirical and numerical work (Agent Based models) in these areas. Her work has an interdisciplinary flavour as she has been using models and methods from statistical physics and financial mathematics to address important economic questions.
