From the psychology of trust and deception on The Traitors, to memory and mental health on BAFTA-nominated BBC Morning Live — Dr T makes brain science unmissable television.

Who is Dr T?

Most performance consultants diagnose behavioural problems. Dr Tharaka diagnoses the human mind behind them. Trained as a Medical Doctor and Consultant Psychiatrist in the UK, he spent over 20 years understanding what drives human behaviour, decision-making, and performance — then took that knowledge where most psychiatrists never go.

He brings that depth to organisational transformation programmes, keynote stages, individual coaching, and TV screens — where organisations like Shell and Heineken, and audiences on BBC, ITV, and Channel 4, have experienced the difference that brain science makes in practice.

He doesn't just explain the science. He makes it actionable — for your people, your culture, your audience and for you.

  • The neuroscience behind what makes people follow, trust, and perform for a leader.

    Topics: Emotional Intelligence · Psychological Safety · Trust · Communication · Body Language.

    Topics: Organisational Cohesion · Psychological Safety · Trust · Communication.

  • The master topic underpinning everything else. For audiences who want to understand how the brain actually works — and what that means for how they live, lead, and perform.
