Dr Chris Warner was my Director of Studies at Robinson College, University of Cambridge, during my Mathematical Tripos, as well as supervisor in Vectors and Matrices, Differential Equation, Dynamics and Relativity, Electromagnetism, and so on.

In addition to his academic guidance, Dr Warner was also in charge of my well-being at Cambridge, and his support enabled me to make the most of my studies. I am grateful for his mentorship and guidance, which played a significant role in my academic and personal development.
