What is the best certification for a HR student interested in Training?

I am Sushmitha Sridhara from Bangalore, India. I am doing a Masters in International HRM from the University of Westminster, beginning this September. Being a trained Experiential Educator, my passion lies in Training & Facilitation. While in London, I wish to pursue a certification programme or an additional course in a subject related to L & D. My options are Emotional Intelligence, CBT in the workplace and such. 

I seek your guidance regarding the best course/s to study along with my Masters so that I create a set of valuable skills as a corporate trainer. 

Thanks.
