In complex legal proceedings, the role of an expert witness has evolved well beyond validating pre-formed arguments. Today, experts are increasingly integrated earlier in the case lifecycle, shaping strategy, clarifying what is provable, and influencing how legal teams frame their theories from the outset. At the same time, rising scrutiny, more sophisticated Daubert challenges, and rapidly shifting technical demands are redefining what it means to be an effective expert.
Drawing on her experience building and managing expert teams in high-stakes matters, DOAR’s Vice President of Experts, Eleanor Hamilton, shares her perspective on how the expert witness landscape is evolving and what legal teams should consider when developing effective expert strategy today.
Q: How has the role of expert witnesses evolved in complex litigation over the past decade?
The role of an expert witness has shifted meaningfully from that of a credentialed narrator to a strategic case asset. A decade ago, experts were brought in (often late) to validate positions already formed by counsel. Today, the best litigators integrate experts far earlier, sometimes at the investigation or pre-filing stage, so that the expert’s analytical framework can actually shape the theory of the case.
Daubert challenges have also grown more sophisticated, forcing experts to be more than just credible in their field and defensible in their methodology. Experts are now expected to be rigorous AND communicative, two qualities that don’t always coexist naturally. The most effective experts today add value beyond their CV by distilling and communicating complex topics in a straightforward, compelling way, and staying composed under pressure while doing so.
Q: How do you approach aligning an expert witness’s experience with a legal team’s broader litigation objectives?
Aligning an expert’s experience with a legal team’s broader objectives goes beyond just lining up the right CV with counsel’s wishlist of credentials and/or industry experience. There is often a tension that lies between retaining the most credentialed expert and the most useful one. A highly decorated PhD who cannot simplify a complex concept for a jury, or who struggles under cross-examination, can do more harm than good in many cases. The best approach starts with a frank conversation about the legal team’s overarching objective and their specific case needs. Is the primary goal to persuade a jury? To influence a sophisticated arbitral panel? To support a favorable settlement dynamic? Each of those objectives may call for a different expert profile. From there, alignment is about role clarity.
Q: Which expert disciplines are most sought after in today’s litigation environment, and how has the profile of “in-demand” experts changed throughout your career?
Demand for experts has always ebbed and flowed around trending disciplines, and we’re certainly seeing that in areas like cryptocurrencies, autonomous technologies, aerospace, and more broadly, AI. But today’s demand is increasingly driven by regulatory waves and emerging technical domains that move faster than ever.
What’s interesting is that expert demand in litigation tends to lag financial market events and regulatory shifts by about 12-24 months, which is actually an advantage for firms that are paying attention. Take the crypto boom as an example: as digital asset markets peaked and then collapsed, so did the wave of fraud, misrepresentation, and insolvency cases that followed, bringing a surge in demand for blockchain experts and the like. We are seeing a similar dynamic play out now with AI systems, where regulatory action and high-profile failures are beginning to generate the first wave of cases that will require experts who can explain how a model works, why it produced a given output, and who bears responsibility. The underlying pattern is consistent: markets, regulation, and litigation come first, and expert demand will follow.
At DOAR, we use this baseline knowledge to stay ahead. We don’t think about expert needs as filling a requirement; we aim to know what cases are coming down the pipeline so that we can pre-position talent accordingly. We continuously map the market, build relationships before cases arise, and place both testifying experts and consultants when firms need them most.
Q: Given your background, what changes have you observed about the expert witness industry? In your view, what differentiates a truly compelling expert from a good one in the context of high-stakes disputes?
The market for experts has become more competitive and more transparent. Clients and counsel are vetting experts more aggressively, rates have risen for the right talent, and reputational risk is higher because there is more visibility than ever into an expert’s past. Opposing counsel can more easily mine prior testimony, published writings, and even social media for inconsistency. The practical implication is that a “good” expert’s past work can become a liability if it contradicts the current engagement, which raises the bar for intellectual consistency across an expert’s career. As a baseline, a credible expert should have:
- Earned authority in their field
- Credible independence
- Strong composure
- A background that has been checked for conflicts, past positions, and reputational vulnerabilities
The difference between a “good” and truly “compelling” expert is their ability to hold their ground under pressure without becoming defensive or combative. Finding this combination is at the core of what we do at DOAR. We don’t rely on credentials alone; we assess an expert’s communication skills early in our vetting process and we have frank conversations about the specific technology or issues at the heart of any given matter. We like to see how our experts might handle a challenging question about the limits of their own analysis before opposing counsel gets the chance to ask it. We have also built in structured feedback loops with our clients to track expert performance. That intelligence feeds back into how we evaluate and develop our expert teams, and it is what allows us to predict who will perform when it counts.
Q: What’s one misconception you often encounter about expert witness work that you wish more legal professionals understood?
That expert work is mainly about the report. Some of the highest-value expert work happens upstream: clarifying what is provable, shaping which theories are viable, narrowing issues, and preventing a team from building on assumptions that will not survive scrutiny. When an expert is engaged early and used well, that expert can reduce risk and sharpen the case strategy long before testimony.
Q: How do you measure success when building and managing expert teams for clients?
Success starts before the case does. On the building side, we try to identify and recruit experts early, ideally before they have accumulated too dense a testimony history. There is a sweet spot in finding someone with enough real-world credibility to be persuasive, but not so much prior testimony that opposing counsel can spend a deposition walking them through potential inconsistencies. From there, we think carefully about the breadth and depth of the bench in any given practice area. Most matters need an expert who can range across several related issues; others demand someone with extraordinarily narrow, niche expertise that no generalist could replicate.
DOAR’s automotive practice is a good illustration of how we think about team architecture. We maintain a balance of academics, industry executives, and former regulators, and within that, we have coverage that runs from electric vehicle systems and autonomous technology, all the way down to highly technical sub-specialties like the mechanical design of self-actuating torque wrenches. That range is the result of continuously building relationships ahead of demand. Another important element of team building is to surface conflicts, prior testimony, publication positions, and/or reputational considerations. These are conversations that are far better to have at the recruitment stage than midstream in a high-stakes matter.
On the managing side, our work spans the full lifecycle of an expert engagement, beginning with how we structure the initial interview process, all the way through to trial, where our consultants can step in and support witness preparation as needed. Beyond our own process, when we think about how a law firm should measure expert team success, the metrics tend to cluster around a few key questions. Did the expert survive Daubert intact? Was their deposition consistent with counsel’s theory of the case? Were they able to communicate complex material in a way that was clear and persuasive to a non-specialist audience? And perhaps most telling: did opposing counsel move to limit or exclude them? A Daubert challenge, counterintuitively, can be a sign that the expert was genuinely threatening to the other side. The final measure is reputational, and it may be the most important one over time. The best experts are repeatable, where each engagement adds to a body of work that makes them more credible (and desirable) the next time. This is the standard we hold ourselves to at DOAR when we think about who belongs on our teams.
Q: What excites you most about DOAR as one integrated company with three business lines, and how does that position us as a trusted partner for attorneys from expert testimony through trial?
There are so many things to be excited about. For decades, DOAR has operated as a leader in the jury and trial consulting industry by working alongside prominent attorneys on the most complex matters in the country. That track record has established our foundation. Aligning our three business lines explicitly sets us up as a single, trusted source for expert insight, jury intelligence, and trial execution, working as one team with a unified view of the cases we support.
As an integrated company, our clients get strategic continuity across their case lifecycle, greater coherence during the moments where pressure is highest, and a trusted advisor who holds the full picture. We serve as a strategic extension of the legal team, and now, we’re better positioned to deliver a greater level of excellence to clients who had previously only been exposed to one side of our business.
