<!-- <li> One can know everything about a matrix if one knows the spectrum of this matrix. </li>
<li> Rewriting the equation does not critically change the solution, but it can help our understanding. </li>
<li> A great discovery solves a great problem but there is a grain of disvoery in the solution of any problem. </li> -->
<li> In mathematics you don't understand things. You just get used to them. <i> - <a href = "https://en.wikipedia.org/wiki/John_von_Neumann" style="color:blue"> John von Neumann </a> </i> </li>
<li> What is important is to deeply understand things and their relations to each other. This is where intelligence lies. The fact of being quick or slow isn't really relevant. <i> - <a href ="https://en.wikipedia.org/wiki/Laurent_Schwartz" style="color:blue"> Laurent Schwartz </a> </i> </li>

<b> About Me </b>
<p>   </p>
Simon is an ordinary person born and raised in <a href="https://en.wikipedia.org/wiki/Macau" style="color:blue">Macau</a> (the former and the last colony of Portugal).
He is a first-generation college student in his family. He traveled to <a href="https://en.wikipedia.org/wiki/Beijing" style="color:blue">Beijing</a> in 2011 and started studying mathematics since then.
In 2015, he came to <a href="https://en.wikipedia.org/wiki/Hong_Kong" style="color:blue">Hong Kong</a> to continue his journey of PhD in mathematics.
His career started in <a href="https://en.wikipedia.org/wiki/College_Station,_Texas" style="color:blue">College Station TX</a>.
He aims at understanding the real and yet complex world, on which he desires to make an impact, through his mathematical knowledge and expertise.
Currently, he focuses on Financial Modeling from a more practical and realistic perspective. As a quantiative researcher, he tries to leverage right amount of science to
make considerable revenue.
