Quant Trader (taught myself, ode,pde,machine learning, bayesian networks, advanced statistics, probability, some quantum finance)

Have worked thru' several books on analysis, calculus, geometry, and some on topology. (informally taught several undergrad and grad math tuitions to students (ofcourse for $$$), but no proof (& no tax )

Willing to go for PhD Applied Mathematics in US.Few people suggested MS and then PhD, but being higher on age now (26), I wish I could get into PhD directly...(not even sure MS app will be accepted)

feedback.....
