David S. Boyle, PhD

Affiliate Associate Professor, Env. and Occ. Health Sciences (Primary department)
I am currently a senior program officer at the Program for Appropriate Technology (PATH) and I am part of the Diagnostics Group within the Technology Solutions Global Program. I lead the Tuberculosis Diagnostics Portfolio in addition to leading key (principle or co-investigator) efforts into developing diagnostic tools for infant HIV, polio virus, integrated nucleic acid diagnostic systems for TB and Clostridium difficile, and multiplexed immunoassays for micronutrient deficiency assessment. In terms of technology development, I am primarily interested in the field of isothermal nucleic acid amplification technologies and their application in simple to use yet high performing diagnostic assays for use in low resource settings in the developing world. I lead a variety of projects that investigate isothermal amplification, novel enzymes for nucleic acid amplification, novel nucleic acid extraction/preparation technology and and their co-integration into low cost diagnostic tests.
