+## My research:
+I work on Higgs physics at CMS in particular the single Higgs decay to two muons in Run 3
+
+## My expertise is:
+Data analysis for Higgs physics
+
+## A problem I'm grappling with:
+Using machine learning techniques for signal extraction in a bump hunt search for the H to mu mu decay
+
+## I've got my eyes on:
+Looking at all of the final run 2 luminoity to observe rare Higgs decays!
+
+## I want to know more about:
+Modern data analysis tools to speed up my workflow
