Hello, and welcome back to ACRAC. I'm Jed Wolpa. And we've got a fantastic show for you today.

I'm thrilled to have with me two wonderful practitioners and researchers, Dr. Lorenzo

Berra, who is an anesthesia and critical care attending and the medical director for respiratory

care at Massachusetts General Hospital, and also Dr. Roberta Santiago, who is an MD-PhD

research fellow and is trained in pulmonary and critical care medicine and in respiratory

therapy, also working with Dr. Berra at MGH on some really fascinating research. And what

You want to start? Okay, so I, I'm from Brazil and I started my training in Brazil and

turned on my medicine and pulmonary. And by the end of my residency, I was missing something now,

and I had a rotation in a research center in another state in São Paulo. And there I get the

opportunity to work and do my PhD with Professor Marcelo Mato. And after this contact there,

I get to know Lorenzo and Robert Cosmaric here in the US and end up coming here to do my

BOSS doctorate fellowship. Fantastic. And just tell me because it's so interesting, what,

tell a little bit about what made you decide to do the respiratory therapy training. That's a

little unusual but very neat. So when I got here and we started doing research in critical care
