My research is driven by two passions:
(1) High precision metrology including the definition, realization, and dissemination of the SI (The International System of Units).
(2) Experimental tests of General Relativity.
Research in both topics require the design, setup and operation of precise mechanical apparatus in addition to careful data analysis and reliable estimation of the involved uncertainties.
I am very passionate about these two topics and I hope to share some of my enthusiasm with these web pages.
