In studying the regulation of gene dosage, his lab described the first known biological role of a microRNA in the mammalian system, ultimately revealing a network of microRNAs that titrate the dose of key cardiac gene networks that dictate cell fate and differentiation.

Rapid developments in the field of synthetic biology and its associated tools and methods, including more widely available gene editing techniques, have substantially increased our capabilities for bioengineering — the application of principles and techniques from engineering to biological systems, often with the goal of addressing «real - world» problems.
