I aspire to inspire, and I believe that mathematics is for all. I enjoy writing, designing, composing music and studying how mathematics relates to everyday life.
How did I start out?
In Form 2 (Grade 8 in the US), I visited Murray Bourne’s website Interactive Mathematics as well as his blog, and from the latter I found Miss Celine Loi, a private maths tutor in Singapore. Challenged to find real-life uses of quadratic equations thanks to #1 of Murray’s post, I found Plus Magazine, which changed my life in many ways:
- It featured the Maths in The City competition (now gone), which I entered and was encouraged to keep writing;
- From the Maths in The City Twitter feed, I found out about the Ada Lovelace Day mentorship; and
- It shaped how I wrote the content for the new website of the Department of Mathematics at CUHK http://www.math.cuhk.edu.hk.
My hobbies are very varied. Apart from indoor activities like reading and knitting, I also like travelling and various sports: running, swimming, tennis and archery. In my spare time, I keep learning new things. In fact, I want to write, draw, sing and speak about mathematics and its applications to a wide audience in the next five years from 2016 to 2020.
I hope my story inspires girls to thrive in mathematics and the sciences just by being who they are: girls.

Disclaimer: This is not an exhaustive list. I am still pursuing opportunities to write.

2011 Maths in the City: Hong Kong Space Museum (East Wing) – Highly Recommended (My only surviving copy of the article at Maths in the City. The video, which could not be watched in the PDF, is embedded below.)
Formal bio (as of 24 August 2017):
Cassandra Lee Yieng is a published author, artist, musician and mathematician. She majored in mathematics and minored in information engineering at the Chinese University of Hong Kong (CUHK) as a bachelor’s student, and took up computer science as a master’s student. She is now a mathematics teacher.
She caught press attention and broke through obscurity in 2011 thanks to her “highly recommended” entry on the Hong Kong Space Museum (East Wing) at the “Maths in the City” competition hosted by Professor Marcus du Sautoy of the University of Oxford.
She was nominated for SCMP Young Post Junior Reporter of the Year in 2012. In spring and summer 2015, she supplied the text content of CUHK’s Department of Mathematics’s new website at www.math.cuhk.edu.hk. She spearheaded the 13th issue featuring women mathematics graduates from CUHK.
The article which made her a published author was on Emmy Noether, and it was published on Ada Lovelace Day 2015 in the book More Passion For Science: Journeys Into The Unknown, edited by Suw Charman-Anderson, founder of Ada Lovelace Day. An earlier and abridged version of that article appeared in the 12th issue of the aforementioned departmental Newsletter. She spearheaded the production of the 13th issue of the said newsletter, the topic of which was “CUHK’s Maths Girls”.
She also has published an article on tessellations for the 7th issue of IMOment, the newsletter for the International Mathematical Olympiad in Hong Kong in 2016. She blogged at Huffington Post and studied at Adobe Education Exchange. She spoke at TEDxCUHK 2016, the theme of which is “Light in the Dark”, on her mathematical journey, and earlier in 2015 at the Y.W.C.A. Hioe Tjo Yoeng College’s career talk on mathematics and writing.
In 2017, she did copywriting for the Julia Robinson Mathematics Festival, an initiative to bring students aged 10-14 into the joy of learning mathematics. She spoke on International Women’s Day at CUHK on how girls can shape the future through STEM (Science, Technology, Engineering and Mathematics). Her graduate #fintech thesis was on sentiment analysis of Chinese financial texts. She also joined the writer’s community known as the Just-Us League.
Never seeing herself as a nerd, she aspires to inspire girls to thrive in mathematics and the sciences, showing them that they can make a difference in the world in spite of their gender.
Her hobbies are very varied. She loves reading tangible books and electronic ones, as well as knitting, but she also loves to travel and play various sports from tennis to archery. In her spare time she keeps learning new things.
