My research is in the field of microscale transport phenomena in the presence of interfaces. I study theoretically and experimentally the transport of heat, mass and momentum in the presence of a single drop, bubble or microsphere. Applications of my research are in micromanufacturing, drag reduction, microfluidics and remediation schemes against global warming. More information at http://www.columbia.edu/~da2203/
