About me:

My name is pronounced like 'Yerney Barbeach'. Jernej is the Slovenian equivalent of Bartholomew. Sanctus Bartolomaeus => Shem-Bertelemej => Shem-ernej => Jernej.
I was born in 1976 in Šempeter pri Gorici, Slovenia, EU (Yugoslavia at the time).
I spent my childhood in western Slovenia, near the border with Italy, and two hours away from Venice. My hometown is in the Alps, not far from the Adriatic Sea. Here is my favorite wild animal: capra ibex.
As an undergrad, I lived in Ljubljana (capital of Slovenia).
I then lived in Pittsburgh, Pennsylvania, USA, and Boston, Massachusetts, USA. I now live in Los Angeles, California.
I like sports. My favorite ones are triathlon, swimming, running and (mountain) biking.

Volunteer work, writing:

Since 2009, I have been trying to promote a social security agreement between the United States and Slovenia, to benefit citizens of both countries. I spoke to several high-ranking Slovenian officials, and promoted the cause in Slovenian media. Here is my blog posting from 2012 (in Slovenian) about why it is needed: blog Kvarkadabra. In March 2019, the agreement has been signed both by the parliament of Slovenia and US Congress. It entered into force on Feb 1, 2019. You can see it here.
My translation of "Južni otok", a well-known Slovenian poem by Kajetan Kovič, into English.
I wrote a guide for new Carnegie Mellon students to help them settle into their life in Pittsburgh.
I wrote a guide on applying to grad school in US (in Slovenian): Kako uspeti pri prijavi na študij na ameriške univerze.
