To keep up with the abundance of papers that catch our eye, everybody in the lab brings one paper to our journal club (second Tuesday of the month) to discuss what they learned, what they liked (and disliked) in an informal discussion without any slides.
The lists below are a highlight of what caught our attention and give some insight into the broad interests of the lab.
