Difusión y Transferencia


In 2003 I created a business unit that manufactures, installs and offers services around electromagnetic shielding. This unit created a spin-off in 2010 and is now called Tekemi S.A. It has sales for US$4 millions in all Latin america.

I have 6 worldwide patents (1 pending). Four of them has been licensed to MRI manufacturers (Philips, GE and Siemens).

I have given seminars and training courses for non-experts to around 200 people in Chile and several countries in Latin america.
