There are many great reasons to engage in research, and you do not need to have previous experience in research to do so! The Transfer Research Timeline outlines a basic plan of action for transfers who are interested in getting involved in research while they are at UCLA.
If you are considering graduate school and would like to graduate in two years, it is best to start exploring your research options during your first couple of quarters at UCLA. You can adjust this timeline accordingly if you are planning to stay three years rather than two, and/or if you are planning to do research in more than one field.
Research is going to look different in every major and in every lab. If you are unsure what research is, why to get involved in research, and/or how to get started in research be sure to visit the Undergraduate Research Centers, attend workshops and browse the online resources available through Powell Library, and explore other opportunities here and here.
