+## My research:
+Machine learning for CMS collider data, with emphasis on boosted-object reconstruction, jet-substructure signatures, and heavy new-particle searches. Trigger, reconstruction, and analysis software for preserving rare patterns in dense detector data.
+
+## My expertise is:
+Taking enormous datasets and extracting physics, mostly by parallelizing computations.
+
+## A problem I'm grappling with:
+Trying to test some algos with hls4ml, but I don't have hardware.
+
+## I've got my eyes on:
+FPGAs, maybe GPUs?
+
+## I want to know more about:
+Best outdoor bouldering spots in the CERN campus area.
