The population of grad students and postdocs is relatively modest because I like to stay close to the data. Also, I rarely travel and I'm generally a "hands on" kind of PI--this means I'm always around and enjoy helping move projects along.
That depends... I expect to work with people that are highly motivated to do experiments and enjoy thinking deeply about data. I'll be asking you about the results of your last experiment on a daily basis. You should also be OK with me doing experiments for your project--I've contributed data to many papers from the lab.
Thanks for asking--you're a unique and beautiful snowflake! I look for people that are good at critical thinking. Having good hands is equally important. Also, strong analytical skills (i.e. ability to code) is a big benefit.
