I'm trying to work out how to identify the person who started a process so that I can assign the human tasks in the workflow to them. Does anyone know how to get the details of this person.

I know how to assign the task to them once I have their details, that's just the section of code below as part of the bpmn file

      <potentialOwner>
        <resourceAssignmentExpression>
          <formalExpression>#{user}</formalExpression>
        </resourceAssignmentExpression>
      </potentialOwner>
