You have to send me all of the following information and data:
Make sure to not "link" any files (like google documents), but attach them all as file attachments.
That's basically all! We can go from there and have a meeting to discuss further steps. Note that this advice (including the one below) applies to all kinds of applications, for PhD positions or anything else.
Whether you apply for a PhD or a summer internship, or anything else: If I can recognize that you did not read this webpage here, then I will not even reply, no matter how many reminders you send or how strong your transcript or CV is. This is because I am only accepting exceptional people to my team, and those who are not even capable to inform themselves about the available positions and requirements, are clearly not worth my time. Being a good scientist is about more than just having a strong transcript; you also need to be reliable and competent in general -- and not reading what I have to say about my positions is a red flag that cannot be compensated. In Industry, nobody would apply for a job without reading the job announcement, so clearly becoming a top-tier scientist has even higher requirements!
So, in summary, what do you need to do to at least receive a reply from me? Two things:
The bar for me replying is really very low: Tell me about your qualifications, your goals, attach all required documents (see above), and you are sure to get a friendly reply.
I receive applications from all over the world thus with all different kinds of traditions regarding the usage of titles. To create a common ground, let me explain a few rules regarding naming conventions:
What do I prefer? I strongly prefer an informal first-name basis. (I really dislike formalities.) So please feel free approaching me like that from the very beginning. We can also switch to a first name basis after we exchanged a few emails if you prefer. (Note that scientists are all on a first-name basis among each other. Only with students it's sometimes different because of the age gap. I am however still very happy with a first-name basis; it's all about content, not rank!)
