I am the author of three books on writing.  The depth and breadth of my experience -- academic qualifications plus my previous forensic work and extensive real-world language experience, including writing speeches for the CEO of General Motors, qualifies me to give testimony if my expert opinions would assist the trier of fact.

It's been said that the quality of an expert lies in how well he/she explains what he/she does.  I consider this one of my key strengths.  My reports are clear, straightforward, and as non-technical as possible.  I have been deposed several times..
