Dobrodošli na predstavitveni strani Andreja Srakarja.

Welcome to the webpage of Andrej Srakar.

I work as a mathematician and artificial intelligence researcher at the Jožef Stefan Institute and econometrician and Assistant Professor at the School of Economics and Business, University of Ljubljana. Working on and finalizing my 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 also coordinate present activities of the Young Statisticians Europe initiative itself.

My main research interest is in probability theory. Probability is still a developing area in theoretical mathematics with a lot of unexplored possibilities. In my research I try to explore combinations of probability with a diversity of other mathematical areas, ranging from pure number theory and algebra, to representation theory and dynamical systems. As example, free probability is on the bound of probability and operator theory. SLE combines probability with complex analysis and geometry. Other interesting combinations and many research questions abound. As I started and continue my research in a special economic field called cultural economics, I combine these two directions in my research.

I combine probability research also with research in mathematical statistics, machine learning and econometrics. More specifically, I research Bayesian asymptotics for different Bayesian approaches - aspects of Bayesian asymptotics are largely underresearched in many areas of Bayesian methods. I also research in symbolic data analysis, interesting area which studies methods for aggregated data referring to the statistical concept of symbol. As economist by my first PhD, I develop and research methods in econometrics. Namely, causality in economics is a foremost topic of study, but causal situations in economics are complex and not easy to adequately grasp. I study and develop approaches to treatment effects under network interference, an area still underresearched in causal inference, and able to provide methods to adequately address dependencies and interconnections of economic subjects. This leads also to my research in high-dimensional econometrics, in particular spatial, network and text econometrics. Also, I'm interested in how to account for nonnormal stochastic error in many empirical economic situations. To this end, I develop and study semi and nonparametric approaches based on data depth. Dynamic effects of economic interventions are another important area for econometricians - I develop and study spectral estimators for time series and panel data. Finally,  question on efficient estimation in econometrics is now open with presence of Bayesian and machine learning possibilities, due to rise in computational capacities. I study and develop appropriate Bayesian and machine learning econometric approaches (as compared to the present frequentists ones) for various economic situations in micro and macroeconomics.

I was recipient of the prize for best presentation for my article "Level densities for general β-ensembles: An operator-valued free probability perspective" at the New Researchers Workshop of the 10th Bernoulli-IMS World Congress in Probability and Statistics in Seoul, Korea in 2021.

I am also member and contributor to home 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.

Being an active fellow of the Royal Statistical Society for many years now, I am highly active within RSS as well, in particular as committee member of the RSS Emerging Applications section as well as one of the organizers of the legendary RSS Discussion Paper Meetings.

I try to be as active as possible in research that I perform. You will find me as an always active participant at the webinars of One World Probability, POPS, Percolation Today, Gary Chamberlain online seminar in econometrics, Online Causal Inference Seminar, Virtual Time Series Seminar, and different online seminars of the ISBA association. I have helped to initiate webinar series of One World YoungStatS, Cultural Economics Online Seminar Series and The SHARE International Seminar Series (SISS), naturally you will find me there, organizing and discussing as well.

Listen also to advices to young mathematicians by the 2024 Abel prize laureate Michel Talagrand.

I am writing a blog on my daily research and academic work. You can read my posts and follow it here.

My current research interests lie in six broad directions:

• Schramm-Loewner evolution outside of planar domain and connections of complex analysis and probability theory: extensions of SLE and related objects in d>=3; conformal topologies and scaling limits; mating of trees and related techniques in d>=3; scaling limits and SLE with several complex variables; probability on complex manifolds (e.g. Stein, Oka); interacting particle systems and complex analysis in d=2 and d>2;

• free probability tools to study general beta random matrix ensembles: spectral and level densities for general beta ensembles; RMT and free probability; properties of Jacobi ensembles; point and set-valued processes for random matrix objects; probability measures for the study of random tensors; random matrix theory and percolation (FPP, LPP); epsilon-independence; Boolean freeness; cyclical and conditional cyclical freeness; free central limit theorems and asymptotics for non-commutative probability; concentration inequalities and free probability; traffic probability;

• random algebraic geometry: zero sets of random polynomials;

• probability for artificial intelligence and computer science: central limit theorems for neural networks and deep and generative learning; Bernstein-von Mises asymptotics for Bayesian machine learning problems; probability for model-free, error-driven and federated learning;

• econometric theory and mathematical statistics: causality in econometrics; development and study of appropriate Bayesian approaches for econometric models; modelling of measurement error in econometrics; development and study of novel machine learning econometric models and approaches for cultural economics, economics of ageing and macroeconomics;

• Bayesian causal inference, causal inference for non-Euclidean and high-dimensional data, and causal inference for 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 an active member of Text, functional and other high-dimensional data in econometrics: New models, methods, applications (HiTEc - CA21163) COST action. This Action integrates cutting-edge analytic developments involving innovative sources of information, such as text, functions, perceptions or imprecise data, in econometrics. Within this action I perform active research on the bound of probability theory and high-dimensional econometrics and mathematical statistics.

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)ijs.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.

I'm member of ERCIM Working Groups on Computational and Methodological Statistics (specialized team in Functional Data Analysis, http://www.cmstatistics.org/FDA.php) and Computational and Financial Econometrics.

As of May 2018, I have been continually listed among the top Slovenian economists by number of points, total research output and exceptional achievements in the main Slovenian research base SICRIS.
