Thanks for all your comments. Sorry if I was not clear in my earlier post, but I am not a Statistician/Biologist/Sociologist as some of you implied here. My undergrad major was in Mathematics, but I switched field in graduate school.
I am aware of these other job options mentioned by a few of the posters above, but my major concern is that I do not have necessary background to get my foot in the door because I come from a different field. When I say I have knowledge of C and Python, I only meant that I can do scientific numerical computations (Partial Diff Eqs, Monte Carlo etc. nothing too fancy. I am not making any softwares or games!) with those langugages, but I am definitely not an expert, not even close. 

 When you look at job descriptions for some of the positions mentioned above--especially the Data Scientist--they clearly say I must either have formal education or work experience in Java, data mining/machine learning, AI etc., which I have none. Is it really enough to "learn things on my own" in order to get my foot in the door? I can certainly learn these on my own, but I am not quite convinced that this will help me get noticed (of course, I won't get anywhere if I don't learn, but that's not the point here), because I am not involved in nay projects, and frankly, I woundn't be able to get any thing done before I graduate, which is happening soon. I guess, what I am looking for is a place where I can start small since I've *some* programming background, work as well as learn, and not simply spend time learning on my own with no concrete results.  Is this feasible at all, or am I just day dreaming?

Thanks for your input. Please keep'em coming!

@ Nalini, I will try to get in touch with you.
