I am on the Editoral Board of Journal of Mathematical Physics and in charge of "Quantum Field Theory and Operator Algebras".
A submission should be made through the online submission system. If you would like your paper to be handled by me, you should state so on the cover letter and in the "submission comments" box in the online submission system, as explained in the official submission instruction page.
