A common way to find research is going onto the CoE research website where you can find all the ongoing research on campus and their affiliated faculty. From there you can find their contact information where you can email them and express your interest in their research and ask if there are any openings in their lab.
Another wonderful place to find research opportunities as an undergrad is at the Materials Research Laboratory (MRL), they have a number of research opportunities available on their website.
The pandemic presents unique challenges for the on-campus researchers, and the restricted access for undergraduates in research buildings makes the prospect of joining a research group intimidating. There is plenty of work to be done remotely, including data analysis, design, and simulations, all activities that can safely be done remotely. Most research groups have had ample time to adjust to the new reality of research in the COVID-19 era and have transitioned a majority of their projects into goals that can be accomplished remotely.
If there is a professor that you are interested in working with, their faculty websites are a good place to start. The current research areas are commonly listed on the website, along with the graduate students working on each topic. Reading papers published by the research group is a good way to learn more about the work being done, and to have specific talking points that demonstrate your interest. After you have done your research, you should send a well crafted personal email to the professor of choice expressing your interest, sharing relevant skills, and asking if there is any openings or opportunities for you to become involved in the lab environment. If there are no projects open or no grants available, ask if you can sit in on group meetings, that is a great way to receive research exposure and increase your presence in the event that positions open.
