About me

I’m a Ph.D. candidate at ESSEC Business School in Paris, France. My main research interest focuses on Cryptoassets. It is important to not reduce the cryptospace to the well known Bitcoin cryptocurrency. The cryptospace is characterized by three subcategories; payment cryptoassets (i.e. cryptocurrencies), platform cryptoassets and decentralized applications. Click here for more information.
I study the cyclical behaviour in the cross section of cryptoassets with heterogenous regime switching models to highlight the heterogeneity in the cryptospace. I further investigate the benefits of including a portfolio of Cryptoassets in otherwise completely diversified portfolio.
By exploiting the heterogeneity of cryptoassets (rather than solely relying on a combination of the largest cryptoasset) I show that the risk-return profile of portfolios is significantly improved.
