Jack Lewis
Dr Jack Lewis, neuroscientist and broadcaster, uses brain science to help teams focus, decide, and perform better. A neuroscience speaker with a UCL PhD, he co-wrote Sort Your Brain Out and has presented for the BBC, Sky, and Discovery.
Dr Jack Lewis is a neuroscientist, broadcaster, and best-selling author who makes brain science useful for businesses. He gives dozens of keynotes a year, sharing research-backed techniques that help people focus, decide better, and get more out of their brains.
Jack holds a first-class neuroscience degree from the University of Nottingham and a PhD from UCL, where his functional MRI research investigated audiovisual sensory integration. He has presented science based series for the BBC, Sky, and Discovery, plus two series of Secrets of the Brain for Insight TV, and co-wrote the best-selling Sort Your Brain Out.
Through his consultancy, Neuroformed, Jack brings a neuroscience-informed perspective to communications campaigns for companies across a range of industry sectors. His insights shaped the restructuring of Deloitte's pitch for Tesco's audit business, which added £100 million to Deloitte's bottom line over a decade, and the Sweat to Spark campaign for Müller and Myprotein, which showed how exercise primes the brain to be social.
His keynotes cover cognitive performance, decision-making in sales and negotiation, creativity, resilience, and unconscious bias. Audiences leave with habits they can apply straight away, from simple changes that sharpen focus to a clearer understanding of how risk, reward, and bias shape the choices their customers and colleagues make.
For organisations that want teams to think clearly and decide with confidence, Jack offers neuroscience in plain English from a researcher with over fifteen years of television experience.
Topics, sessions and talks
The brain is capable of far more than most people realise, yet bad habits and inefficient thinking patterns often hold it back. Dr Jack Lewis, co-author of the best-selling Sort Your Brain Out, shares practical, science-backed techniques to boost cognitive function, sharpen focus, and improve memory. Drawing on research into diet, exercise, and stress, he shows how small daily changes add up. The result is a set of habits that lift performance, creativity, and resilience.
Every decision is shaped by subconscious evaluations of risk, reward, and uncertainty. Dr Jack Lewis draws on neuroeconomics and his own research background to show what drives human choices, from a client weighing up a proposal to a counterpart at the negotiating table. His insights have helped businesses refine their sales strategies, including a restructured pitch that secured a multimillion-pound contract. Sales and commercial teams come away with practical ways to align customer decisions with business goals.
Creativity is a process, and like any process it can be optimised. Drawing on historical examples and current neuroscience, Dr Jack Lewis explores how the brain generates new ideas and solves problems. He looks at how brainstorming sessions can be restructured around the way the brain works, sharing evidence-based strategies that help teams produce breakthrough ideas more consistently. Organisations come away with practical ways to build a more innovative culture and a lasting competitive edge.
High-pressure environments demand resilience, yet chronic stress can erode mental and physical health. Dr Jack Lewis examines the neuroscience of stress, explaining how to harness its benefits while avoiding burnout. With a focus on practical daily habits and mindset shifts, he provides a roadmap for maintaining peak performance without the long-term costs of stress overload. Whether in leadership roles or frontline positions, attendees gain the tools to strengthen their resilience and sustain high levels of productivity.
Unconscious biases shape perceptions and decisions in ways most people never notice. Dr Jack Lewis reveals the psychological mechanisms behind these hidden prejudices and offers evidence-based strategies to reduce their impact. Combining current research with real-world examples, he shows how bias creeps into everyday judgements at work. By addressing biases at their source, organisations committed to inclusion can make fairer, more effective decisions and build a more equitable workplace for everyone in it.

No. PepTalk adds no booking fee, so you pay the speaker's fee and nothing beyond it. The service, from shortlist through to contracts and event-day logistics, is included. For repeat or multi-event bookings, PepTalk can agree preferential rates with your procurement team.
Share your event date, audience, format, objectives and budget, and PepTalk sends a hand-picked shortlist within 24 hours. Each suggestion comes with a profile, a fee and a recommendation on the strongest fit. Once you choose, PepTalk handles contracts, travel and logistics through to event day.
The typical fee range is the speaker's standard in-person fee in their home market, shown in their local currency. It moves with format, location, date and session length: virtual sessions and shorter slots usually cost less, while international travel and peak dates cost more. Send your brief to PepTalk and the team will confirm the exact fee in your currency.
Not all of them, and it makes no difference to your booking. PepTalk's network of 15,000+ speakers covers talent the team works with directly alongside speakers represented by agents and agencies worldwide. PepTalk approaches the speaker, negotiates the fee and handles contracting either way.
Three to six months ahead is comfortable for most events, and 12 months is better for large conferences, peak-season dates or one specific in-demand speaker.
