Breathing life into regulatory change

...and helping you to navigate the complex and uncertain world of financial regulation

Dr Sian Lewin aka The Reg Doctor

I am an expert in financial regulation, with over 20 years of helping  large banks such as JP Morgan, UBS and RBS build their regulatory strength in response to regulatory requirements. 

I have diagnosed regulatory compliance issues and worked to improve or restore the regulatory health of financial organizations. I also specialise in project and programme mangement and enjoy creating order and structure in dynamic situations of uncertainty and complexity.

In 2017, I was awarded a PhD from the London School of Economics. My systematic research explored the challenges faced by banks in dealing with the volume and speed of regulatory change following the 2008 financial crisis.

More recently, I have ben working independently within the RegTech sector. I also teach at the LSE and hold a visiting post-doc fellowship with Copenhagen Business School.


From established banks to new FinTechs, I am here to guide you through regulatory changes and work with you to create innovative solutions that ensure your firm is protected from regulatory and reputational risk. 


Developing technology to help regulated firms meet their regulatory obligations requires a deep understanding of the issues that cause them the most pain. I can provide these insights so you can develop products that will meet your customers’ needs.


I can provide specialist expertise to assess the technical quality of your risk and regulatory projects and / or deepen the regulatory knowledge within your organization through a bespoke training programme.
