She's the scientist who just hit the headlines when she was trapped alone on an island for weeks on end by the brutal winter weather.
INSIDE EDITION's Steven Fabian tried to get through the icy waters that imprisoned her.
She works on Friendship Long Island, off the coast of Maine where she runs a research center called The Lobster Conservancy.
But, when the waters between the island and the mainland froze solid, Diane got completely cut off. She couldn't leave the island and boats with supplies couldn't get through to her.
Some of her friends were so concerned they actually organized an air drop, throwing food parcels out of an airplane's window.
Diane's lone figure can be seen waving as the plane went over. Her dog, Sula, was sniffing at one of the boxes.
When Steven Fabian heard about Diane's plight, he decided she could probably use a little company right now.
The only way to reach her is by boat and to do that you have to break through the ice.
At first, Fabian made headway across the bay, but the closer he got to the island the more difficult it became.
The thick ice surrounding Dr. Cowan's house can be seen in a video.
Finally, a tiny figure waved from the dock on the island.
Then, it's time for Steven Fabian's own "Dr. Livingston, I presume" moment.
He said, "Nice to meet you, I'm Steven."
Dr. Cowan responded, "Steven, a pleasure."
He climbed onto the dock. He was Diane's first visitor in over a month.
She said, "Oh, a human face!"
Fabian responded and asked, "I know, it's been so long. How long were you by yourself here?"
She responded, "35 days."
Diane told INSIDE EDITION she used the time to master new skills.
"I did all these things I never did before. Like, roast coffee beans. I always had the beans, but I never roasted them because I never needed to. I baked my own bread," she explained.
And although she said she came to appreciate the solitude, it will take her a while to get back to normal.
She told INSIDE EDITION, "I haven't driven a car. I think it's going to be like an amusement park ride when I get in a car."
And as we spoke, there was a moment of drama.
"The ice is moving. Yeah, you guys have to leave. The tide's coming," she warned.
That's right, after more than a month with no company, Diane good-naturedly kicked us off the island!
She said, "It's been a pleasure you're welcome anytime! Thank you."
And with that, Fabian left the lobster lady alone again on the island where she spent so much time on her own.
