初めましてをメールで使いたいときには何と言いますか？
Nice to meet youではおかしいですよね。

ちなみに大学の教授宛なので、文頭に使える丁寧な表現をお願いします。

Title: Request for interview -Taro Yamada

Hello Professor Smith,

I am a graduate student at ABC University, currently working on international politics and looking for a researcher position next year.

From your recent post on National Post and your website I understand your department is currently working on political framework to solve global warming problem, which is one of my major research topics. Would you mind sparing some time for me early next month, to talk about my current work and about potential future position?

などと言ったように、単刀直入に自己紹介から用件に入るのが良いかと思います。特にemailの場合は。
