Are there any ways I can get involved with research during covid-19 so that I can boost my application? Would it be feasible to still volunteer at labs? I'm a rising senior by the way.
Personally, I have done independent research, and it is probably the safest option as of the present moment. Depending on where you live and what sort of independent research you are doing, you can enter into competitions about your research. (Linked Here is one such example: https://sustainability.asu.edu/sustainabilitysolutions/programs/solutionsfestival/sustainabilityfair/). Right now, it is not feasible to volunteer at many labs due to the fact that there is a global pandemic going on, and many professors are unlikely to take requests for research assistance. Independent research is the likely way to go.
To keep this community safe and supportive:
Note that you probably can't enter the ASU competition... it is just there to show an example of the types of competitions you can do. Additionally, some colleges like Harvey Mudd allow you to submit abstracts relating to your previous research.
