+              Hongguang is a Scientific Software Engineer at Quantstack.
+              He obtained a Master degree in image processing from University of Rennes 1 in 2010
+              then he went to Canada(QC) to work on research project about autonomous vehicle.
+              During that time, he became interested in scientific computing then worked 
+              on a few research projects in France related to open-source scientific computing such as
+              the parallelization of <a href="https://github.com/linbox-team/linbox">linbox</a> (a linear algebra toolbox
+              for cryptography) and the improvement of scatnet(a machine learning package for seismology).
+            </p>
+            <p align="justify">
+              Hongguang discovered the critical role of open-source work in science and is keen to contribute back to a
+              community that gives so much.
