+## My research:
+Neutrino oscillations:
+- Past: long baseline (NOvA, DUNE)
+- Present: short baseline, steriles (ICARUS, SBND)
+
+## My expertise is:
+Selection optimisation, data analysis, model fitting
+
+## A problem I'm grappling with:
+Improve ICARUS neutrino event selection efficiency with neural networks.
+
+## I've got my eyes on:
+Graph neural networks.
+
+## I want to know more about:
+Big data handling, paralization.
