Software and data are ubiquitous, with every organization now dependent on ever more complex digital infrastructure. AI is being infused into every product and service, dramatically increasing that complexity with huge implications for contract disputes and litigation.
Expert witnesses must be able to not just understand the technical issues but explain them in a way that can be understood by lawyers, juries, and judges. This is where Dr. Richard M. Marshall, Principal of Concept Gap Ltd, excels. With a Ph.D. in Computer Science from the prestigious University of Edinburgh, Dr. Marshall possesses a unique talent for rapidly grasping the critical issues at the core of each matter, before effectively and clearly conveying the complex technical concepts involved.
