Mattel designed a Barbie doll honoring Eleni Antoniadou's accomplishments, but what are they?

Eleni Antoniadou's reported accomplishments were so impressive that Mattel designed a Barbie doll based on her as part of its International Women’s Day celebration.

But those "accomplishments" might all be nonexistent. Here's a partial list from the BBC as to suspicions raised:

Claim: She worked on the world's first artificial trachea that was successfully transplanted to a patient.

Counterclaim: She was a postgraduate student at UCL and was remotely involved with the surgery. The transplant ended with one of the biggest scandals in modern medicine, covered here by the BBC. The patient died after his body did not accept the transplant. Long after his death, Ms Antoniadou gave interviews in Greece saying how she had saved the patient's life and how the patient was living a normal life.

Claim: She has been working for a number of years as a researcher at Nasa.

Counterclaim: She attended a 10-week summer school there and took a lot of pictures around the US space agency's facilities wearing clothes with the Nasa logo. Nasa has denied she works directly for the agency, but has not excluded the possibility that she may be working as a sub-contractor.

The Telegraph is also investigating:

The NASA-ESA Outstanding Researcher Award does not appear to exist and Ms Antoniadou's name is not included in Nasa's record of its award winners.
