My professional background
Since finishing university with a degree in Sociology and acquiring a PhD in Sociology and another PhD in Political Science, I have worked as a social scientists and demographer at various universities and research centers, including the Technical University of Munich, the University of Bamberg, the International Institute for Applied Systems Analysis (IIASA) (where I spent more than 17 years), and the Institute for East-Asian Studies, Department of Chinese Studies of Vienna University. I have also worked as a Guest Researcher at Rockefeller University in New York.

In my last position before retirement I was Chief of the Population Estimates and Projections Section at the Population Division of the United Nations Department of Economic and Social Affairs (DESA) from 2006 to 2013. For details, please see the official website of the United Nations Population Division at: http://esa.un.org/unpd/wpp/

I have had a lifelong intense fascination with computers and have developed software and websites for many decades. As an amateur programmer I have written code in Fortran, C, C++, Delphi (Pascal) and VB.NET. I make my websites from scratch in plain html, css and JavaScript - with a littel php if necessary. I love MS Excel, I like MS Word and I work with MS PowerPoint. Adobe Photoshop and InDesign I use all the time (but don't like their subscription model). As an old man, I have tried to learn and use R (which drives me crazy). Early in my career I have done massive data crunching with SPSS. I am also familiar with database development and have designed and implemented large-scale SQL databases for demographic purposes.

As you probably can guess I am a do-everything-myself fanatic. I like to do research, write content, design charts and interfaces, and code and implement websites or software. If I could, I would make the paper or construct the PC on which I work. Probably I am a fossil from a long-gone period befor the division of labor became the norm.
