I have been lurking on PF for a while, so I have done a bit of research on the subject but figure I should get some specific advice from those knowledgeable about my dilemma. Currently, I am a junior Economics major at a Big 10 school, recently admitted into the honors program for my subject. I started my college career in Aerospace Engineering, switching to Economics early in my sophomore year. Now I really enjoy economics, but I have become much more interested in mathematics over this semester since I've been taking Real Analysis. I really enjoy writing proofs and the theoretical approach to higher level mathematics really opened my eyes to the possibility of graduate level work. Here's a quick profile: Undergrad GPA: 3.70 Math Courses: Calculus I-III(A/A/C+), Linear Algebra(A), O&P Differential Equations(A), Real Analysis I(A) Econ Courses: Intermediate Macro/Micro(A/A-), Econometrics I/II(As), Money&Banking(A), Adanced International Trade/Labor(B+/A) Other Courses: Classical Physics(B-), Chemistry(A), Computer Science C++(B+) Research: Summer RA (Possible opportunity to continue into the fall), Senior Thesis As an economics major, do I have any chance for a decent graduate applied mathematics program? I'm afraid my CalcIII grade might kill my chances. Would I have to apply to a Master's in Mathematics, something I know is not usually regarded as a track to a PhD? My interests are really in 'micro' aspect of Economics like Game Theory (which I will be writing my senior thesis on hopefully), which is usually considered a discipline in the mathematics department. I also plan on being an RA for either an Economics professor or a respected Applied Mathematics professor this summer and take the GREs. I'm afraid I came to this realization too late. Next year I am scheduled to take ~9 credits of 400-level Economics as well as a 400-level Math course in Linear Programs. What else should I take to improve my chances? Discreet Math(Number & Group Theory)? Complex Analysis? I am lost in this aspect and I feel like most here are more knowledgeable about a proper course of action than my advisors. So to summarize, what should I do to better my profile? What programs would I be looking at applying to with a realistic chance to be accepted? Thanks for any help or advice you guys might have for me! I appreciate it.
