Reliationship question

Hi gals and guys!
I would love to hear your opinion about the following situation. Here a background: young marriage (4 years), with two year old, both graduate students. Husband leaves to an interview for a professor position to another country and the interview goes, according to him, pretty well. The couple speak about it over the phone and both are very happy and excited. Then the husband comes back home and three things happen:
1. The wife opens the door, doesn't give husband a kiss, just runs back to her laptop, because she is in a middle of conversation with her graduate student colleague about marking scheme for assignment.
2. The husband waits for the wife for about an hour to talk about the interview and celebrate it. But he is very disappointed about the cold welcome. When the wife finishes the conversation, the husband says that "he is disappointed with her reaction and he expected a warm welcome and some kind of celebration of the success".
3. The wife is totally surprised with husband's expectation and pissed of at him that he would expect her to prepare anything in her busy schedule. She is taking care of the baby and studying in the same time and she has no time to spare on celebrations. She knew he is coming back but she planned her evening to include the discussion on marking because it was important do do it before next day.

Now, do you think that husband has too high expectations from his wife, or that he is right to expect some form of affection and celebration of his success. When answering, please specify whether you are a girl or guy.
