who is dr.strauss? what does he want to do with charlie? why does he want to use charlie? what was professor nemur worried about ? what negative result could happen with the experiment?

These are a lot of questions for one space. Dr. Strauss is the neurologist and psychiatrist who performs the surgery on Charlie. He works with Professor Nemur but is much more concerned about Charlie's health and wellness, and conducts therapy sessions with him to ensure he is in good condition.
