What does it mean if a professor does not respond to an email about research in a week I emailed a professor a week ago about any potential undergraduate opportunities he might have in his research lab. I have not yet gotten a response. Is this normal? the end of my email went like this, was I too pushy or was I not explicit enough with my question? would it be rude to send another email asking again? thanks for any comments 


  I would appreciate the chance to talk with you about any possible
  undergraduate opportunities you are currently offering for the Spring
  2016 semester or Fall 2016 semester. I understand you are very busy.
  We could schedule an appointment or I can drop by your office when you
  are available. Please let me know if there is any other information I
  can provide. Thank you, (my name)
This is very common. I am a doctoral student and my advisor is the director of department. Sometimes, it took him two weeks respond my email. You can send him/her again with a friendly reminder as start or you can stop by his/her office. The latter one is what I usually do.
