Expert Witness Experience
Assessed a Loss-of-Revenue insurance claim relevant to a fertilizer company that resulted in the claim being rejected due to a faulty basis.

Experienced as an Expert Witness in technical and economic analysis for process industry-related cases. Capital Project Management experience up to $35 Million USD.

Basically, Expert is an apparel and fabric expert and consultant. This covers the spectrum from fiber to yarn, to fabric, to weaving and knitting, to wet finishing and printing, to garment assembly and garment wet finishing. In Expert's career this was the focus of his work which translated into quality assurance and capacity building in manufacturing facilities.
As his resume demonstrates, Expert did this for many of America's leading manufacturers and retailers.
Expert was also a consultant to several USAid sponsored projects in developing countries to assist in the improvement of productivity and quality and thus raise employment in the industry. He was deployed on short-term visits (2 to 4 weeks) to Serbia (7 visits) Ethiopia twice and once to Rep. of Georgia.
His expert witness work history is brief..... Expert was called to testify in a case involving smoke damage to inventory at a warehouse that had had a fire. This was in Chicago about a decade back. HIs work was highly praised. It involved a search of thousands of invoices for these goods and also an on-site visit to the said warehouse.
Training / Seminars
University Guest Lectures:
“Dynamic Analysis”, “Distillation Control Primer” & “Practical Process Control”, University of Auckland, Chemical & Materials Engineering Dept., 2013-2015;

“Practical Process Control for the Practicing Engineer”: A 3-day course for Process Design Engineers, Process Control Engineers and Control Systems & Automation staff of all experience levels, that teaches the inter-dependent aspects of process plant design, process control, safety systems design & integration and process automation to achieve reliable and robust plant performance. Utilizing a mixture of lecture and case studies that are gleaned from 30 years of real-world experience with operating plants and design projects, this course addresses the large gap that exists between process design and control theory, as it is normally taught, and its practical application. The course also addresses the growing and diverse knowledge requirements forced upon Control & Instrumentation projects and plant staff resulting from the on-going evolution of automation systems and industry standards.
