It sounds like if you want to gain research experience in order to apply PhD in the biological sciences, the best options are
1. working in a lab as a tech
2. getting research experience through an MS
What about a pre-med-intended special masters program (specifically, Boston University Master of Arts in Medical Science), which also happens to require a laboratory thesis as part of the degree, and then continuing working in the same lab for a year? If cost is not an issue, would this make me a better applicant to PhD programs?
