What inspired you to pursue a career in digital forensics?

I started working in investigations and when one of my cases required looking into the target’s computers, I began exploring the idea of using digital evidence for my cases. It also helps that I have an interest in IT.

How has the role of expert witness changed since you started your career?

We used to be asked a lot about methodologies and processes but with lawyers and judges getting savvier in anything digital, we are now asked more in-depth and under-the-hood questions around digital forensics.

How do you effectively coordinate with other experts when handling large multi-jurisdictional cases?

We all speak the same language with technology, and I find that most of the experts I work with are passionate about finding the truth among the zeros and ones in digital evidence and this helps a lot no matter where we come from.

How has your experience as a founding board member of the Singapore chapter of the High Technology Crime Investigation Association enhanced your role as a digital forensic expert?

Working with a group of practitioners from different areas such as consultants and in-house examiners, I gain a wider perspective on how I conduct my investigations. Additionally, the High Technology Crime Investigation Association also works closely with students from the universities, and it is always good to have fresh ideas from them.

You have a wealth of experience as a testifying expert in a range of sectors. Do you find working on cases in a particular sector more challenging than others, and, if so, why?

Testifying as an expert is always challenging and is not specific to any particular sector. All cases are different and will always have a different set of challenges.

As a senior director of Alvarez & Marsal’s forensic technology service, how would you like to see your practice develop over the next five years?

We will continue to expand the team in Singapore and the region, and are likely to enhance the practice with more subject matter experts to support our clients in this region.

Looking back over your career, what has been your proudest achievement?

I am honoured and proud to have worked with many good people, who are committed and passionate about the work they are doing, over the course of my career.
