Purpose

The purpose of this video lecture is to discuss the difference between efficacy and efficiency, components of internal and external validity, as well as estimating effectiveness from efficiency taxonomy.

Meet the Guest Speaker

Karla Galaviz, Ph.D.

I am a North American product. I completed my undergraduate training in Mexico, my graduate training in Canada, and my post-doctoral training in the US. I am an implementation scientist working at the intersection of lifestyle medicine and chronic conditions. My work focuses on testing implementation strategies to integrate proven health interventions and practices in real-world settings.

Currently, I have a K01 award from NHLBI focused on estimating the cost-effectiveness of diverse implementation strategies for integrating cardiovascular disease prevention in routine HIV care.

I also work building implementation research capacity in low- and middle-income countries and am Associate Program Director for the NIH-funded COllaborative research, implementation, And LEadership training to address chronic Conditions across the lifecoursE (COALESCE).
