I finished my Masters in Computer Science at a decently reputed university in the United States. I was (and still am) excited about doing research and I applied to the Ph.D. program at the same university. I was accepted and I started the program this Fall.

Because of my experience in the department, I could start working in a lab from my first day in the Ph.D. program. I'm currently working on a topic that is closely related to my Master's thesis topic. But now I feel that I should explore other areas before committing on a Ph.D. topic.

I've been working on Operating Systems for as long as I remember, but recently, I attended a couple of seminars on NLP and Bio-informatics that got me excited. I don't have any background in either topics. But this makes me think that I should take a semester to explore other areas of research in Computer Science.

How should I go about this?

Update - I told my advisor. He said I should devote 100% of my time on his project. I fired him.

    I haven't spoken to him, yet. Somehow I doubt he would be thrilled about this. He is very driven by publications and he wouldn't let anyone remain in the lab if they're not 100% committed to the work. That wouldn't be a good thing for me if I wanted to return Systems research later.

    Just do it. If your advisor doesn't like it, fire them. You're a first-year PHD student; it's natural for you not to have settled on any specific research interests yet.

First of all, it's better to make the exploration now than later. Having a good place to apply your CS knowledge can be very powerful, and now is a better transition time than you will ever receive in the future.

With that said, there are several bioinformatics courses online that you can try out; one popular one is Coursera. This allows you to spend a few hours per weekend exploring the topic from a well known professor, and can help you decide whether or not you are truly interested. From there, as @ff524 stated, it is best to ask your advisor for information on how to continue applying your skills to both your PhD and bioinformatics.
