Dr Ekaterina Kostioukhina is a medical doctor whose job is to advance research in how to take care of the humans who go into space. Her interest has always been helping people to deal with accidents and disasters - and space is an area where disasters are routine, and every day is a challenge. She was born in Russia, then her family emigrated to Ecuador, and then they emigrated again to the United States, where she did most of her training. After a couple of years in Mexico, she moved to New Zealand where she currently lives. She says exposure to so many radically different cultures has helped her understand humanity more. But, as she tells SBS Western Australia correspondent Christopher Tan, there was a darker reason for some of her moves between countries - human trafficking. In this episode of Weekend One on One, she speaks about her experience as a victim of trafficking and explains that it's a crime that won't go away.
