About me & Publications

You are invited to browse my site. If you want to learn more about my consulting services or to discuss a tailor made workshop for your academic institute or coaching session for yourself, then do not hesitate to contact me.

I enjoy statistics. And I enjoy consulting and coaching/teaching. Add a PhD in mathematical statistics from ETH Zürich and a vast experience in consulting and teaching, stir, and you get something that will bring your understanding of statistics and related subjects to a higher level.

I am very grateful and fortunate to be a student of Vipassana –an ancient meditation technique– as thought by SN Goenka. It found me in early autumn 2008. I see a parallel between mathematics and meditation. One understands mathematics –hence benefits from it– if and only if one does mathematics. Similarly, one understands and benefits from meditation if and only if one practices it. This passage from Susan & Paul in The Power of Small Changes inspires me.

“When you look back upon your life, what will be more important to you than [an empirical and rational] practice that leads towards peace within yourself?”

Academic background and professional experience
In 2008 I obtained my Ph.D. degree in mathematical statistics from Seminar for Statistics, Department of Mathematics, ETH Zurich, with a dissertation on fast rates of convergence for adaptive classification (pattern recognition / machine learning / support vector machine). Then, I worked in Institut Teknologi Bandung (ITB) Indonesia as a senior lecturer in statistics and mathematics, and in Vrije Universiteit Amsterdam as a postdoc in Statistics for Life Sciences group with topic on neuronal morphology and connectivity. From June 2012 until July 2015, I worked as a Senior Research Associate in Management Information System group, Department of MTEC, ETH Zurich, providing data analysis (with R) and statistical consulting for postgraduates. From September 2016 to June 2017, I was employed by Wood Technology group, Department of Applied Wood Materials, EMPA, Dübendorf, providing survival analysis of experimental data in details of a European project and preparing reports and publications. Since 2018 I am a member of the Statistical Consulting Team of Department of Psychology and since 2019 I work as Biostatistician at Office for Animal Welfare & 3R and as Research Associate  of Dept. of Mathematics at University of Zurich.

In the past fifteen years I have acted as a lecturer in Mathematics and Statistics at ITB, have taught classes and supervised graduates at ETH Zurich and University of Zurich.
