À propos de moi
I'm Stefan, a PhD candidate at the University of Novi Sad (MSc, GPA 10/10) and a full-time peer review coordinator at an international scientific journal. I analyze survey, experiment and customer data in IBM SPSS, R and Python, from t-tests and regression to PLS-SEM, CFA and machine learning. Every number I deliver comes from code I ran on your file, and you get that code. My sample reports use real public data. Message me your research questions and I'll tell you which analysis fits, free.... Plus d’infos

Expérience professionnelle

Doctoral Researcher, Quantitative Methods

College • Indépendant

Doctoral research in quantitative tourism and climate analytics at the Department of Geography, Tourism and Hotel Management. - Built a fully reproducible R pipeline (RStudio projects, fixest, ggplot2) linking monthly municipal tourism statistics from the Statistical Office of Serbia (2010-2026) with ERA5-Land climate reanalysis from Copernicus, including elevation correction. - Designed and preregistered the analysis plan on OSF (two registrations), fixing hypotheses, variables, models and inference rules before seeing results. - Ran simulation-based power analysis and minimum detectable effect calculations. - Estimated PPML (Poisson) panel models with high-dimensional fixed effects. - Validated results with randomization inference, Romano-Wolf multiple-testing correction, equivalence testing (TOST), out-of-sample holdout and 54 robustness and placebo checks. - Collected Google Trends data as a demand signal. - Produced publication-ready tables and figures in English and Serbian.

Manuscript Administrator, Peer Review Coordination

Admini • Temps plein

Jun 2026 - Present • 5 mos

Run day-to-day editorial operations for a high-impact international peer-reviewed journal. - Technical screening of new submissions: formatting, reference lists, figures and tables, author and affiliation details, declarations and compliance with journal policies. - Coordinate peer review between authors, editors and reviewers: invitations, reminders, revisions and decision letters. - Track deadlines across a steady flow of manuscripts and keep papers moving from submission to decision. - Handle author queries clearly and professionally in English. Reading research papers, methods sections and reviewer reports every day has given me a reviewer's eye for what makes an analysis clear, complete and defensible. I bring that standard to every project.
