I am having couple issues here. First I am an International student and English is my third language. I am very shy and having tough times approaching people for help. I am writing my Master's thesis (in Art History) and I am still in the beginning and while I struggle in formulating my thesis and question, I know what is my topic going to be about. There were two academics who have written about this topic and I do not know how to connect with them and perhaps ask for a help with literature or advice and perhaps discuss my topic for ideas. My thesis advisor hasn't been responsive to my emails and last semester she was on sabbatical which slows me down significantly. But he is a wonderful advisor and have given me great direction regarding the topic and what arguments would have been possible to discuss.
I would welcome any suggestions on how best to approach a professor/ academic from a different university/ organization to help me with literature choices, give me a feedback on my topic choice, and with general help to work on a research topic.
