There are 3 PhD positions advertised on university's website and I am interested in two of them. University welcomes to give more than one choices for which candidate should be considered. For both positions requirements are similar. I know the names of professors who will supervise these PhDs but I am not sure if they are the only ones who will judge the applications. Moreover, it is written to upload cover letter in university's application system not to sent to Professors directly.
I am confused how should I address Cover Letter to be considered for both positions. Currently, I have the following
PhD Candidate Search Committee
{Department name}
{University name}
{City, Country}
{postcode}
Dear Members of the Search Committee,
Is it a good way to address in cover letter?
