Contacted the head of a group I want to join, but she didn't reply. What to do now? An institution in New Mexico is offering a scholarship to people that want to join the institution, and I think I may be a good candidate. I contacted the head of the group I would like to join, with a long mail introducing myself, my work, and my passions, and what I could bring to the group. On her page in the Institution webpage is clearly stated that she is the person to contact for who wants to join the group. 

Now 6 days have passed and she hasn't come back to me yet. What do you suggest me to do? I can find on the internet other people that work in the same group under her supervision. Should I contact them? Should I wait more? Should I write again? 

I doubt she just found my professional figure uninteresting, as it really matches what they are looking for. Maybe my mail was too long, she put it aside, and forgot to reply? Should I write her again? 

Is it maybe uncommon to contact directly the head of the group you want to join through a scholarship? 

Thank you.
6 days is not a lot of time to wait. After 2-3 weeks I would send a short followup. 

In general, long emails are bad. The advice I try to follow is keep them 3-4 sentences if I don't know the person and they aren't expecting an email from me. Give them the opportunity to either ask for more details or to setup a call.
