Query SPListItemVersionCollection

Hi,

I need to query Modified and Modified By field from SPLIstItem versions based on below query.

• Modified value is Today and
• Modified By user contains in SPListItem field "KPI Engineer", KPI engineer field is a user or group field
  

            SPListItemVersionCollection spVersions = spListItem.Versions;
            var result = from spVersion in spVersions.Cast<SPListItemVersion>()
                               select spVersion;

How to achieve this from version collection based on CAML query or LINQ?
