I am a postdoctoral fellow in the research group of Professor Daniel G. Nocera in the Department of Chemistry at MIT.

In 2006, I completed my Ph.D. in chemistry at Harvard University with Professor Charles M. Lieber.

My research in the Nocera group focuses on the application of semiconductor nanocrystals (quantum dots) to bio/chemical sensing, chemical imaging in biological microenvironments, and energy conversion. A common theme is the need to introduce specific interactions with the quantum dot excited state. This is achieved by permanently tethering small molecule chromophores to the quantum dot surface. In this way, the sensitivity and specificity of the molecules can be leveraged by the broad excitation cross section, tunable energy levels, and photostability that are unique consequences of the semiconductor crystal lattice. I collaborate closely with the Bawendi group in pursuit of this work.

More broadly, my professional interests include the synthesis and surface modification of low-dimensional materials, optical imaging and nanophotonics, and the application of new materials to problems in biotechnology and sustainable energy.
