(studied bio-informatics) - SoP for bioinformatics for PhD

I am seeking admission to PhD in bio informatics in an indian research institute. I am posting the statement of purpose here. Kindly go through the same n correct it.

STATEMENT OF PURPOSE:
During the years of my graduation and post graduation, I did not have a clear cut idea of what to do with my life. Had a financial crisis at home. I worked to support my family. My working period helped me decide what I want to do with my life. A research career in biology- thats what I am truly interested in. I have worked in a few research institutes as aproject assistant and as a computer technical analyst in a company. It was during this time that I discovered my fascination for computers and operating systems. But my liking for biology is never less.

I have studied bio-informatics during my graduation and post graduation. Even though I don't have any experience in developing algorithms, I could always use my experience as a computer technician and my experiences in research institutes in the field of bioinformatics. Bio informatics takes help from computer science to find the hidden truths buried in DNA and bio molecular structures which I am curious to find out. I browsed through your course catalogue for PhD. One of the reasons I would like to pursue PhD from your institute is that the course work listed would provide a solid foundation for my long term research career in genomics. Another reason is good faculty profile.

An opportunity in yur institution would definitely help me shape up a better career.

A sentence needs a subject and a predicate. This sentence has only a predicate:
Had a financial crisis at home. --Add "I" to the beginning of it.

Use an apostrophe: that's what I ...

Typo; as aproject ...

Oh, I have a great idea. I do not like the sentences at the beginning about not knowing what you want to do. Those sentences are not helpful! I think the first sentence of the essay should be this one:

I have studied bio-informatics during my graduation and post graduation. Even though I don't have any experience in developing algorithms, I could always use my experience as a computer technician and my experiences in ...---Look at how powerful this is!!! Wow, what a great intro.

That first paragraph is weak, and I think you should kill it. Start with this GREAT second paragraph, and continue its theme. :-)
...long term research career in genomics. Another reason is good faculty profile. Instead of saying this, about the faculty profile, kill the whole first paragraph and make room to write a little about some book or article written by a faculty member. Write about some specific faculty members whose work you admire. Just an idea...

Great job!!
