Which has been your most interesting case to date, and why?

Every case has interesting facets and provides for unique challenges. The beauty of my profession is that we continue to learn from every case, building on our pre-existing knowledge and experience.

On what types of matters do clients come to you most frequently at present?

I am primarily asked to support post-M&A disputes, based on my experience and expertise in transaction advisory, business valuation and auditing, including the preparation and assessment of business plans. However, I am also often involved in a wide range of other matters, including commercial disputes and investment arbitrations.

How has the role of expert witness in arbitral proceedings evolved since you first started practising?

There have been some noticeable changes. First, the use of experts has become more common in continental Europe, especially where clients seek our advice at an earlier stage of the proceedings. Second, today there is an abundance of available data, including in arbitration proceedings, so the management of information has become vitally important, and the ability to identify and analyse relevant information has become one of the most critical issues.

What are the challenges of managing an abundance of data and information? How can these challenges be overcome?

The challenges are twofold: first, from the universe of available data, the relevant information must be identified and extracted; and, second, it must be analysed. Identification of relevant data relies greatly on experience, in a specific industry, relating to a specific issue, with a specific system, or with a specific software application. To efficiently and effectively extract and analyse data, we benefit from the intelligent use of software and tools. Not only do these tools enable a faster processing and understanding of the information, they typically also support the interpretation and presentation of relevant findings resulting from the analysis.

How can clients maximise the benefits of experts when involving them at an earlier stage of the proceedings?

Involving the expert early on allows for a focused process towards submission. Based on their understanding of the claim, the expert may suggest a preferred method and approach for the assessment of damages. On this basis, the targeted identification, collection and analysis of data can avoid amassing unspecific and potentially irrelevant information.

To what extent is a damages expert obliged to independently research and assess information or is it advised for them to work on the assumptions derived by clients and counsel?

While there is the odd engagement where an expert is purely working based on instructions (ie, is essentially a calculator), I consider the true benefit of an expert to be his or her independent opinion. However, an independent opinion requires an independent conclusion on the relevant issues, which in turn, is based on an independent assessment of the facts, based on credible and reliable data. To this end, independent research to identify and/or verify the information that forms the basis of the expert’s opinion is an essential aspect of the value an expert can provide.

What steps can younger experts take to improve their chances of getting testifying appointments? Is there an important role to play here for experienced practitioners?

To improve their chances, young practitioners must always deliver high-quality work – this will be recognised by the ones deciding about their potential future appointment. Also, they should seek opportunities to build their reputation in the market by speaking at conferences, publishing articles, or getting involved in professional organisations. The important role of experienced practitioners is to nurture these talents, and to allow and support their growth.

What is the best piece of career advice you have received?

Be patient, always be humble and, most importantly, be true to yourself.
