Profile

Age 26
GMAT - Math 50/51 Verbal 30/51

Undergrad- Bachelor of Engineering (Computer Science) GPA -3.2 From India.
Work Experience 3.6 years (Software engineer) In Wipro Ltd.

I am going to Canada this fall to study MBA in Finance from Memorial University of Newfoundland.
I have deep interest in Financial Economics and want to go for PhD in USA.

Studied many advance math courses in Engineering (attached list of courses MBA + Undergrad Math)

Can I get admission in PhD program in USA (Under Top 50) not aiming for Top 10.
Please suggest anything which I should do to improve my profile. I will give GRE next fall and will take Econ courses along MBA Finance courses.

Memorial University in not a top university in Canada but it is very affordable university. Will it impact my chance of admission that I am not from Econ background and I studied in not so famous university.
