Schedule a meeting with your boss and with heading "90 days goal". You can bring along and as well ask your boss to come up with at least list of 5 things that he wants you to get completed within that timeframe. You can even talk to your boss in regard to what are different projects he is involved in and how you can help him. And go on working accomplishing that if you need any help during that time ask colleagues/boss. At the end of 90 days talk about what need to be completed within 1 year time frame.
Take your initiative don't wait work to come to you. Be proactive not reactive.
If I were you I would do this.
