The Out Campaign: Scarlet Letter of Atheism

Currently employed at MITM AB - Co-owner and Manager, working on a new medical record iotaMed and translations of children's books from Swedish to Polish.

Updated September 26, 2013

PhD Dissertation September 25, 2009

I presented my thesis on September 25, 2009. Click the link above for the thesis, photos, and video.

Personal data

  • Born in Wabrzezno, Poland, 1973.
  • Married (to Martin Wehlou), two children (Milena Wehlou and Julian Wehlou)
  • Lives in Uppsala
  • Countries of residence: POLAND (February 1973 - December 1995), BELGIUM (January 1996 - October 2001), SWEDEN (October 2001 - onwards).
  • Here are the links to my cv in pdf format and to the list of my publications and scientific presentations.

Education

  • 1992-97: University of Torun (Copernicus University), Poland, masters degree in theoretical mathematics with teaching qualifications. Diploma officially approved as equivalent (or more) to a Belgian "Licentiaat Wiskunde" with "Pedagogische kwalificatie", and thus automatically approved in all European Community countries. Thesis: "Continuation method for contractions and applications in differential calculus". Graduated with top honors.
  • 2003-2009 (of which almost 19 months, 7/6/2005 - 1/1/2007, on maternity leave): Ph.D. from Uppsala University, Sweden. Thesis: "Digital lines, Sturmian words, and continued fractions" defended on 25 September 2009.

Languages

  • Fluent in Polish, Swedish, Dutch, English and Russian (well, in the latest one I am not so fluent any more...). Planning to learn French (or Italian, or maybe Spanish - I love them all!).

Scientific Presentations

Teaching material written 2000-2008

  • Autumn 2000, Complexe getallen (Complex numbers, in Dutch), an interactive Mathematica notebook designed, programmed and written by me during my work for the Exploot project (led by Professor Ivan Cnop) at the Flemish University of Brussels, Belgium. The notebook has been used as teaching material for Dutch speaking students. It can be found on the home page of Exploot (you have to click on "Fourier en complexe analyse" left on the page, then click on "complexe getallen" left on the next page).
  • Spring 2001, Complexe veeltermen (Complex polynomials, in Dutch), an interactive Mathematica notebook designed, programmed and written by me during my work for the Exploot project (led by Professor Ivan Cnop) at the Flemish University of Brussels, Belgium. The notebook has been used as teaching material for Dutch speaking students. It can be found on the home page of Exploot (you have to click on "Fourier en complexe analyse" left on the page, then click on "complexe veeltermen 1" left on the next page).
  • Spring 2001, Complexe getallen en de meetkunde (Complex numbers and geometry, in Dutch), an interactive Mathematica notebook designed, programmed and written by me during my work for the Exploot project (led by Professor Ivan Cnop) at the Flemish University of Brussels, Belgium. The notebook can be found on my page on geometry (the last item on this page).
  • November 2008, Minnesanteckningar for deltagarna i workshop GRUPPER (Notes for the participants of the workshop GROUPS, in Swedish), notes I wrote for the "Sonja Kovalevskydagarna" at Uppsala University. Here you can find the text as pdf.
