A Letter to Prospective Graduate Students

Dear Prospective Graduate Student,

I am always looking for talented, hardworking, graduate students who are interested in pursuing their graduate studies at UW-Madison and interested in working with me. Like many other professors, I receive many emails from prospective international graduate students who are interested in finding a position and are wondering whether I will be able to offer them a position in my research group or not. Please keep in mind that I will not be able to respond to most of these emails due to the sheer number of the requests. I apologize in advance for not responding to these emails.

My recommendation to all the students who are interested in joining my research group is to go ahead and apply to the graduate program at the ECE department of UW-Madison. In your application, please indicate that you are interested in working with me and that you have contacted me (if you have done that). Additionally, please make sure to choose the correct area of interest (Applied Physics – Electromagnetic Fields and Waves) when applying. In the January-February timeframe, I will go over all the applications and the documents of the applicants who have indicated an interest in working with me and I will recruit new graduate students from among the people who have applied to the department and have received admission. Please notice that I will not be able to comment on your chances of getting admitted to the department. This is up to the admission committee. I also will not be able to make any comments about your chances of getting a position in my research group before you submit a complete application to the department and are admitted to the department.

I do hope that this letter clarifies some of the questions that you may have.

Sincerely Yours

Nader Behdad
