I am an Information Technology/Cybersecurity consultant & expert witness who can provide support for discovery demands and interrogatories, data analysis/review of production, deposition consultation (recommended follow-on questions, clarification of industry jargon, etc.), & expert report/testimony.

I can provide independent forensic analysis of computers and mobile devices, as well as evaluate other expert witness reports arising from forensic analysis.

I have over 25 years' overall IT experience, with the past 16 years supporting the US Department of Defense in various IT roles. I hold the internationally-recognized cybersecurity CISSP-ISSAP certifications from (ISC)2 as well as an active TOP SECRET National Security Clearance. A sample of past case work is available along with my CV.
