Dobrodošli na predstavitveni strani Andreja Srakarja.

Welcome to the webpage of Andrej Srakar.

In his Fields Medal video, Hugo Duminil-Copin described profession of a probabilist. This is who I am (or want to be).

I work as econometrician/Scientific Associate at Institute for Economic Research in Ljubljana and Assistant Professor at the School of Economics and Business, University of Ljubljana. Finishing second PhD in mathematical statistics at the Faculty of Mathematics and Physics, University of Ljubljana. Fulbright scholar in economics, Indiana University Bloomington, United States (2011/12).

I am Coordinator and Co-Editor of the YoungStatS project in the framework of Young Statisticians Europe (YSE) as part of the FENStatS association. Project is formally supported by the Bernoulli Society for Mathematical Statistics and Probability and the Institute of Mathematical Statistics (IMS). YoungStatS project is aimed to presenting and promoting recent leading literature in statistics and mathematics, organization of One World YoungStatS webinar series for younger scholars in these areas, and enhancing cooperations of younger scholars. Jointly with One World Probability seminar, One World YoungStatS it is the only online seminar series supported by both Bernoulli Society and the IMS.

I am (or want to be) a mathematician and economist and bulk of my research interests lies on the intersection of probability theory, random geometry and mathematical analysis. In my research work I try and aim to combine and explore combinations of probability theory and different other areas of mathematics, such as complex and functional analysis, number theory, algebra, geometry and topology, partial differential equations and combinatorics.

I sometimes use/apply this in the development of novel estimators and mathematical approaches in applied probability, statistics, data science and econometrics (causal inference, Bayesian approaches, nonparametrics, functional data analysis, textual data analysis, machine learning), physics, biology and computer science.

I am also member and contributor to home (Covid-19 Sledilnik and Podnebnik) and abroad citizen science initiatives. I try to communicate my findings and contribute to the scientific community at large. I think opening science and information/data is beneficial for scientists and general public.

More specifically, my current research interests lie in the following directions:

probability and random geometry (Schramm-Loewner evolution, random matrices and free probability, interacting particle systems);

complex analysis, functional analysis, partial differential equations;

high-dimensional econometrics and causal inference;

Bayesian statistics;

symbolic data analysis;

applications to cultural economics; SHARE database; macroeconomics; and citizen science data.

My activities take part being among other member of European Mathematical Society, Institute of Mathematical Statistics, Bernoulli Society for Mathematical Statistics and Probability, Royal Statistical Society (I'm member of committee of the RSS Emerging Applications Section and the RSS Discussion Paper Meetings Committee), Econometric Society, European Economic Association, American Economic Association, International Association for Applied Econometrics, International Society for Bayesian Analysis, Society for Causal Inference, American Statistical Association, International Health Economics Association and Association for Cultural Economics International.

I'm currently coordinating two larger projects of online seminars and blogs:

YoungStatS - The blog and One World YoungStatS webinar of Young Statisticians Europe (YSE)

Cultural Economics Online Seminar (special sessions), Association for Cultural Economics International (as part of my tasks of the Communications Board of ACEI; in 2021 CEOS seminar was founded based on my initiative and proposal by the editors of EconomistsTalkArt.org blog)

Do get involved if interested and please write me an email on first.last(at)ier.si and/or first.last(at)ef.uni-lj.si.

Editor-in-chief of Review of Economics and Economic Methodology (REEM), indexed by EconLit. I am Editor of the Cultural Economics & the Creative Economy Book Series, published by Palgrave Macmillan. Book Series is at present the only book series in cultural economics on international level.

I am joint Coordinator of the Young Section of the Slovenian Statistical Society and active member of Young Statisticians Europe coordination.
