Your username appears to be a real name. Our user name policy says here:
Use of a real name allows contributions to be more easily traced to an individual. This may make a contributor more vulnerable to issues such as harassment. You should consider the benefits and drawbacks of making substantial contributions under your real name before doing so, especially if you are interested in editing subjects which may be politically sensitive. While it is possible to rename accounts (see Changing your username), a record of the previous name will still exist.
If you are happy with using a real name for your account, then I hope you enjoy editing Wikipedia! If you would prefer to change your name, please go to Changing your username
