Assistant Professor of Accounting

I am an Assistant Professor of Accounting at Rotterdam School of Management of Erasmus University. I am passionate about disclosure research; particularly on the real effects of disclosures. I currently examine the effects of innovation-related disclosures on capital markets, firms, and competitors.

I am interested in data science and actively use textual analysis techniques to extract and collect information from corporate disclosures or web sources.
