I am a Visiting Fellow within the Economics and Finance Subject Group, at the University of Portsmouth Business School.
Prior to joining Portsmouth Business School, I worked for 10 years (2004-2013) in the financial industry, at Hargreave Hale Stockbrokers (U.K.), Frontier Capital Management (London) and Piraeus Bank (Athens) and gained experience from several senior positions as sovereign fixed income & market risk analyst; hedge fund quant modeller, developer & arbitrageur; and portfolio relationship officer in structured products, wholesale and corporate banking; whilst I have also held a position as a Lecturer in Finance at the Business College of Athens.
My expertise is in Macro-finance, Monetary Economics, Financial Engineering, Portfolio Theory, Asset Pricing, and Banking. I am thoroughly learned in these areas with sound knowledge of recent practice.
I recently (February 2015) defended successfully my Ph.D. thesis - titled “Essays on Applied Financial Econometrics and Financial Networks: Reflections on Systemic Risk, Financial Stability & Tail Risk Management”, supervised by Dr. Renatas Kizys, Dr. Dimitrios Gounopoulos (University of Sussex) and Dr. Ioannis Chatziantoniou.
The thesis consists of five essays which address and assess how the global financial turmoil of 2008 challenged the functioning of the financial markets. More precisely, in the aftershock era numerous repercussions were felt throughout the world, resulting from a plethora of cross-border and cross-entity interdependencies. An initially systemic banking crunch - where cash-strapped banks stopped lending, liquidity abruptly dried up, and credit conditions deteriorated - metastasized into a sovereign debt crisis in the euro area which devastated public finances and provoked higher sovereign default risk. Motivated by the intensity, the magnitude and the speed with which shocks propagate in the entire financial system, the thesis presents five essays which: i) provide important implications for understanding systemic and liquidity risk by employing financial networks; ii) identify the critical role of credit derivatives on enhancing financial stability and assess the two-way feedback ramification, triggered by government interventions, on financial stability; iii) analyse policies designed to mitigate financial contagion and propose approaches to enhance tail risk management with portfolio asymmetries and asset monotonic volatility; iv) capture the fluctuations of emerging currencies and financial assets during distress, asymmetric economic conditions; v) propose a Bayesian three state switching regime approach to price financial assets.
My research focuses on and aims to develop a greater understanding of asset pricing, systemic risk, monetary policy initiatives, and macro-financial imbalances; to bolster financial stability, to derive sound policy recommendations for the monetary policy authority, and to enhance more efficient management of investments and portfolio risk, with the employment of networks, information theory and state-of-the-art Bayesian, financial and macro- econometric techniques.
Additionally, my research promotes and manifests the advantageous role of derivatives, hybrid securities, structured portfolio and structured credit products on understanding financial markets, and reinforcing the management of financial risks, with the complementary use and endorsement of financial engineering, computational and mathematical finance.
