Which is the best major choice for this career?

I am looking to become a pharmaceutical scientist and was wondering which path is the best to enter this field. Ideally, I would like to work with helping come up with new medicines and improving existing ones. Is it best to major in chemical engineering with a minor in biology or to go to graduate school for a PhD. in microbiology/biochemistry? I hear that the market for PhD scientists is not the best, but at the same time if someone is looking to move up in the company a PhD may be necessary. Is going to pharmacy school and then trying to work in industry a viable option?

Analyze different programs such as this and see if you can figure out what the correct background is. I didn’t take time to look to see if required undergrad courses are listed. Pick 10 big state schools and check their pages

For pharmaceutical science, the two most useful majors are chemistry and chemical engineering. You will find lots of both in the pharmaceutical industry.

A PhD is necessary in this field, to be a “scientist” it’s more or less required by definition. Look up doctoral programs in pharmaceutical science and see what the requirements are and what backgrounds most of the students have.

A undergrad degree in biology, microbiology, biochemistry, chemistry, chem e, genetics, or a similar field would all be applicable.
