Nanometer-sized materials represent a natural size limit of the miniaturization trend of current technology, and they exhibit physical and chemical properties significantly different from their bulk counterparts. The research interest of Hongkun Park lies in developing detailed physical and chemical understanding of these nanostructures and applying this knowledge to possible technological applications. Current research efforts toward these general goals are centered on two areas: quantum optoplasmonics and nano-bio interfacing.

The goal of his quantum optoplasmonics effort is to develop solid-state photonic, optoelectronic, and plasmonic devices that work all the way down to the single photon level. Some examples of these devices include single-photon transistors, electrically driven surface plasmon lasers, and on-chip plasmon sources and detectors. These devices, whose operation is critically dependent upon quantum mechanical principles, may enable all-optical computing and provide the basis for solid-state quantum information processing.

The goal of his nano-bio interfacing effort is to develop new nanoscale tools for interrogating living cells and cell networks. He developed a vertical nanowire platform that can deliver diverse biological effectors into virtually any cell type, and is applying the platform to interrogate intracellular circuits that dictate the functions of primary immune cells. Using the same vertical nanowires, he also developed a highly scalable platform for recording and stimulating real-time dynamics of complex neuronal ensembles and is using this tool to study the inner workings of the brain. More recently, he developed a pipeline for single-cell transcriptomics that is applicable to a broad range of cell types. He is using it to study the cell-to-cell variability of immune, cancer, and neuron cells.

Hongkun Park is a professor of chemistry and of physics and an institute member of the Broad Institute, and is affiliated with the Harvard Center for Brain Science and Harvard Stem Cell Institute.  He is also serving as an associate editor of Nano Letters, and Editorial Boards of Chemical Society Reviews and Chemical Science. He received the Camille and Henry Dreyfus New Faculty Award and Research Corporation Research Innovation Award in 1999, the David and Lucile Packard Foundation Fellowship for Science and Engineering in 2001, the NSF-CAREER Award and the Alfred P. Sloan Research Fellowship in 2002, the Visiting Miller Research Professorship from the University of California at Berkeley, the Ho-Am Foundation Prize in Science, the Camille Dreyfus Teacher-Scholar Award in 2003, a World Technology Network Fellowship in 2004, the NIH Director's Pioneer Award in 2008, was elected as a Fellow of the American Association for the Advancement of Science in 2011, and named as a 2016 Vannevar Bush Faculty Fellow (formerly NSSEFF).
