I am a PhD student in economics at Hanken School of Economics and the Helsinki Graduate School of Economics.

I am interested in competition economics and how frictions shape the competitive structure on product and service markets. My thesis mixes theory and empirics of market frictions (switching costs, entry barriers, search and regulatory frictions, belief biases) on auditing-, electricity-, financial- and real estate markets.

I have been a teaching assistant in introductory micro- and macroeconomics, economics of strategy and behavioral economics. I am an affiliated researcher at the Ratio Institute and a research fellow at Timbro.
