"I’m currently a consultant, mainly with government clients, for a global consultancy firm. My aim is to finish my PhD, but because my work is interesting and great for my career, it is delayed. My doctoral topic is Russian foreign policy, especially its economic and business relations with Armenia on a state and individual level. I am very interested with issues of Armenian economic development."

Quote about Lev Aronian:
I am sure you know a lot of things about Levon. Can you tell for example about traits of character?

"I think that the most prominent characteristic of Lev (and probably me too) is that he loves to learn. If he is passionate about something he wants to investigate and know everything about it. He also likes learning new things, even if it is a challenge or outside of his comfort zone (like dancing, for example!)."
