If you are an undergrad looking to do research, you may want to look elsewhere. I worked in Dr. Yeh's lab for a few quarters and would like to share my experience... Especially for undergrads, this is a toxic workplace. Your value is quantified in the free labor hours you provide. Firstly, she expects all undergrads to commit 20 hours/week for 6 units of credit (5 graded units, 1 pass/no pass). This is already a bit unreasonable. When I first met with her after getting an offer for a position, she told me very clearly that I should be appreciative of the opportunity to do research with her since she gets "hundreds of emails every week" from undergrads who want to do research. Also, the turnover is really high. If after a few weeks, you aren't performing how she wants, you get replaced by a different undergrad. She doesn't value the students who work for her. I was there for two quarters until she interviewed a different undergrad who she thought could replace me and do better work. I was not invited to continue in her lab. For those who do end up with her, be weary of the fact that she has no qualms with getting rid of you with zero notice or warning.
