In my past life I was a mathematician. I did a PhD at the [MASDOC program at Warwick](https://warwick.ac.uk/fac/sci/masdoc), and spent two years in a postdoc position at [CMSA at Harvard](http://cmsa.fas.harvard.edu) and another one and a half years at the [KTH RMSMA group](https://www.math.kth.se/RMSMA/). These days I am a software engineer and steadily forgetting mathematics, not cool, and a problem I am trying to fix.

I am an advocate of free software and an associate member of [Free Software Foundation](https://fsf.org), and have applied the philosophy of free software to knowledge and research. For example I shared my research in Robinson-Schensted algorithms as a [wiki](https://toywiki.xyz) under a free Creative Commons license. I believe anyone can be an academic, seeking truth and sharing their findings with the public.
