The tweet is from a user seeking advice on entering the bioengineering field. The user is a recent graduate in Molecular and Cellular Biology and is considering a master's degree in bioengineering or mechanical engineering. They are interested in tissue engineering, regenerative medicine, and pharmaceutical engineering/drug discovery. The user is open to working on medical devices but would like to gain experience in the other areas first. The user is asking if they should pursue a bioengineering master's degree or a mechanical engineering master's degree. They are also considering taking pre-requisites at a university or doing a bridge program with a school. The user's alma mater accepts many biology graduates without an engineering background.
