I was in academics where Curriculum Vitae are standard instead of resumes, but I have seem some resumes. Are you allowed additional pages (like an executive summary plus a complete description)? Maybe prepare a CV and a resume?
Otherwise, my first impression was like dknguyen's -- I wanted to see more. Specifically, when I saw that someone worked on or with something, I always asked during the interview what it was and what their part was in the project. Be sure you had a significant part to play before listing the item.
Second, you list publications. In a CV, it would be mandatory to give the complete citation for each. Maybe in a resume, you can give at least 3, or attach another a complete list. Community activities, teaching, etc. can also be important to include.
As for the gap and your apparent age, there is no getting around those facts. The more laws that are made to prevent discrimination, the better such discrimination gets hidden or disguised by those who want to do it. On the other hand, a potential employer who wants to give helpful advice is prevented from doing so by the same laws. My advice is to not hide the gap. It will come out anyway. Be prepared and honest, but diplomatic. You might say you were burnt out or you got laid off for business reasons, took time to broaden yourself, and have now reapplied yourself (to wit your current studies) with even more resolve and vigor. Don't overdo it and don't make it sound like you are going back to work only because you need the money. There is a long list on no-no's. Just use common sense. Be careful if your reason for the gap was something personal (e.g., divorce). Everyone faces similar disruptions and problems. However, if it was something more unique, like a child with cancer, then you might indicate the gap was due in part to family health matters. I would not give the specifics in the resume, as it might appear you are trying evoke sympathy.
As for being laid off, if it was a reduction if force, that is likely to be accepted. If it was for poor performance, you may have a problem. In that case, time may be on your side. Things that happened 9 years ago have a dimmed importance today, if you have stayed active.
Good luck.
