Who I am

I’m Nikola Sander, a population geographer/demographer working at the Vienna Institute of Demography, which is part of the Wittgenstein Centre for Demography and Global Human Capital. I completed my undergraduate studies in Geography in Germany and did my PhD at the University of Queensland in Australia. My PhD research looked at internal migration behaviour of retirees in Australia and how patterns might change upon retirement of the Baby Boomer generation. In autumn 2010, I finished my PhD and moved to Vienna, Austria. Take a look at my CV to find out more.

What I do

I do research on past, present and future internal and international migration. This includes patterns and trends in migration flows around the world, interregional migration flows and how they differ across countries, and the migration-development nexus. I’m especially interested in the impacts of internal and international migration on the size and characteristics of local and regional populations.

I’m working on better ways for communicating research effectively and have a growing passion for data visualisation, crowdsourcing and open data/open access. If you would like to collaborate, drop me an email (nikola.sander@oeaw.ac.at) or send me a Tweet, I look forward to hearing from you!

Why I do it

I work in academia because I enjoy finding things out. I’m curious about where and why people migrate around the world and what the consequences are. There are lots of things about migration that we don’t know yet, because it’s a complex phenomenon and the data are very sketchy.

I think it’s fair to say that the scientific community hasn’t put a lot of effort into effectively communicating their findings, making it difficult for the wider public to distinguish biased media reporting from numerical evidence. To enable scientists to develop better communication strategies, it’s essential to make results and underlying data openly available. The Impact of Social Sciences Blog at the London School of Economics has some great advice on how to share academic work.

To share my research and to make it freely accessible on the web, I use ResearchGate, Figshare, Github and Google Scholar. I created interactive data visualisations together with my colleagues in Vienna and code experts at Null2 so that everyone can explore the patterns of international migration. Two of our latest dissemination projects are The Global Flow of People and Internal Migration in Germany.

The geeky stuff

My favourite tool for writing scientific papers is Markdown, which allows me to focus on the content rather than the formatting. I appreciate the clean code and efficient formatting that make Markdown such an attractive option for writing papers. Until mid-2014, I used TeXstudio and Writelatex for writing papers, but I find the LaTeX code a little too elaborately decorated for writing simple text documents. Most papers have more than one author, who are often not familiar with LaTex. Using Writelatex to collaborate with non-LaTeX users is not really a good option. Thank god there’s Pandoc! Writing papers in Markdown and then converting them to MS Word or LaTeX-style PDF makes collaboration so much easier.

For data cleaning and analysis I use a mix of Excel, Stata and a little R. I’ve only just started to get my head around iPython (via Anaconda) and the iPython Notebook. I really like how clean and readable the python code is compared to R.

I’m excited to get d3.js, my favorite data visualisation tool, embedded within the iPython Notebook. Agustín Bartó wrote a blog post on how to do this.

I create circular migration plots using Circos, which (unfortunately) is written in Perl. Any volunteers to translate the code to Python?? For working with SVGs and graphics, I use Adobe Illustrator.

When it comes to writing and sharing code, I use Sublime Text 3 to write HTML5 and JavaScript (beginner level). I push my conference slides and webpages to Github using Git in the console and started to use Github more extensively for collaborative research and visualisation projects. Thanks to Johannes and Andi from Null2 for their help in recent months!

My migrant file

I’m one of about 232 million migrants in the world, having lived outside my country of birth since 2003. Born and raised in Germany, I did my PhD at the University of Queensland in Australia. In late 2010, I moved from Australia to Austria to join the Vienna Institute of Demography.
