Being different can be powerful.

What do you do?

I work with data to help the NHS (the healthcare sector) to understand insights from that data and ultimately improve patients’ quality of life.

My 12 years’ experience focuses on adding transformational value to staff and service users by leveraging real-world data assets. Using analytic techniques and technology, I build Artificial Intelligence and applies machine learning to problems – for example predicting treatment pathways for patients and NHS usage. At IQVIA, I worked to develop a mobile application to help patients digitally record how they feel and share data with healthcare professionals.
My passion for applying technology, correctly, to reveal data insights and tell stories extends beyond the workplace. My volunteering includes Trustee and council member at The Institute of Mathematics and its Applications (IMA); Chair of Early Career Mathematicians Committee; and mentor and diverse role model at STEMette Mentoring Programme.

Why did you choose this field?

Aged 17, I left my family to pursue a first-class education beyond the Hong Kong education system. I have achieved the equivalent of three masters degrees, including a first class integrated bachelor/masters in Maths with Modern Applications from University of York. Since graduating I have applied my skills in the healthcare and life sciences industries, as a healthcare analytics consultant. 

Growing up in two distinct family cultures (Chinese parents in Hong Kong and English parents in UK), I found that girls weren’t encouraged in the same way that boys were. I hope to be a role model to help students to have the courage to follow their dreams.

What do you look at and think, "I wish younger me would have known this was possible"?

To be a winner of Women in Tech 2019 and being the councillor for IMA to help promote Mathematics. And generally, to know I can have a great career as a mathematician.

Why do you love working in STEM?

I feel so powerful when I can use data to improve people’s quality of life, and love helping others to understand the world via numbers.

Best advice for next generation?

if you love something, being a girl won’t stop you. Being different can be powerful, because we can have a different point of view to look at the same problems.
