I think the concept and the plot look really interesting. There were a few mistakes in regards to grammar (missing commas, question marks, etc.) and I'd recommend combining some sentences together, because it can become tiresome to read several short sentences in a row.

The plot is very interesting, and I like Dr. Stein's characterization - it's realistic and consistent. There were a few grammatical mistakes here and there, nothing a quick brush up can't fix. Good job!
