Erika Cheung

That's something he did.

Erica Cheung, she is a lab associate.

She's like, "For being a woman in the sciences and in tech, I was really excited."

Yes.

His concerns also placed him in a painful position with his grandfather, who continued to support Holmes.

Another important figure was Erika Cheung.

Cheung joined Theranos as a laboratory associate and worked with patient testing procedures.

She later described concerns about failed quality controls, the reliability of results, and pressure within the laboratory.

Instead, it encouraged closer scrutiny from journalists, scientists, investors, and regulators.

One reason Carreyrou's investigation was so significant was the testimony of people who had worked inside Theranos.

Among them were Tyler Shultz and Erika Cheung.

Both had raised concerns about laboratory practices, and both had left the company.

And this thing never worked because it wasn't even possible what they were trying to get it to do.

And everyone who worked in Theranos doing actual testing from the lab director to the whistleblowers, Tyler Shultz and Erika Cheung, who they, it was their first job, all of these people said nothing was accurate.

They actually had them, like, throwing out data points to try and make it seem like, oh, the testing was accurate.

And so they had their machines that they would have, like, a, a glue-dispensing robot that would be able to, to move, and so they'll be able to show in the documentary I'm sure it moving and it doing, like, things with a pipette, but they only were able to have one test be validated on that machine, and even that was very dicey, and it was for HSV, hepatitis, and so, and, you know, something very, very serious.

And he had a very difficult time doing so because people were absolutely terrified because everything at Theranos was secrecy and NDAs, and they also had, like, the best lawyer in the country that would go after you, and they really, really made people's lives hell if they even were thinking about saying anything.

And it just shows you how amazing the people who spoke out and spoke to Carreyrou were.

People like Tyler Shultz and Erika Cheung, who were both so young.

They were in their early 20s.
