Samira Asgari is a computational biologist in Switzerland with Iranian citizenship.
As a post-doctoral fellow at the Swiss Federal Institute of Technology (EPFL) in Lausanne, she received a scholarship from the Swiss National Science Foundation to pursue her research in Boston at a top lab with Harvard University.
Because of US President Donald Trump's executive order prohibiting the entry of nationals from seven Muslim-dominated countries into the US, she was prevented from boarding a plane leaving Europe.
That has left her stranded in Lausanne. (RTS, swissinfo.ch, cp)
