About

Jiahao is a postdoctoral associate at the ENI-MIT Solar Frontiers Center, where he works on new theoretical and computational models for the modeling of disordered materials for solar energy harvesting such as amorphous silicon and dye-sensitized organic semiconductors. The new models use techniques from random matrix theory, nonlinear dimensionality reduction and the quantum mechanics of open systems to develop computationally efficient methods for computing electronic properties while taking into account the statistical effects of structural disorder. Jiahao also does fundamental research into the nature of atomic charge and the implications of his research for the understanding of the concepts of electronegativity and chemical hardness. Jiahao is also interested in developing models for multiscale and multiresolution computation of materials properties. Previously, Jiahao was a postdoc with the MIT Center for Excitonics at the Research Laboratory for Electronics, where he worked on developing new empirical models for molecular polarization and charge-transfer Frenkel-type excitons in noncrystalline materials. As a high school student, Jiahao participated in the Science Research Programme of the National University of Singapore, where he helped in the synthesis of novel platinum, palladium and ruthenium organometallic complexes under the supervision of Prof. T. S. A. Hor and Dr. A. S. W. Fong. Jiahao then graduated magna cum laude with highest departmental honors from the University of Illinois at Urbana-Champaign, where he graduated with a BS in chemistry. For his undergraduate thesis, Jiahao worked for Prof. N. Makri where he studied the extent of exciton localization in the photosynthetic light harvesting complex LHC-II using imaginary-time path integral Monte Carlo techniques, as well as memory effects in the quantum dynamics of exciton localization using the quasi-adiabatic path integral (QUAPI) method. After graduation, Jiahao then worked at the Applied Materials Laboratory in the DSO National Laboratories of Singapore, the national laboratory for defense R&D, where he worked on synthesis and characterization of nonlinear optical materials using organic dyes, carbon fullerenes and nanotubes, and inorganic quantum dots. He was also in charge on developing an automated software system in LabView for data acquisition from a continuously tunable visible laser system, as well as developing theoretical models for open-path infrared sensing applications. Jiahao then returned to UIUC where he earned in PhD in chemical physics with the computational science and engineering option. For his PhD thesis, Jiahao worked on the QTPIE empirical charge model for calculating charge distributions in molecular systems and their use for predicting electrostatic properties such as molecular multipoles, polarizabilities and hyperpolarizabilities. Jiahao also worked on the theoretical modeling of the electrochemical Stark effect, developing discrete Smoluchowski models for excitation energy transfer in the light harvesting complexes LH-II and LHC-II, as well as studying the use of diffusion maps for the automated statistical generation of reaction coordinates for ab initio nonadiabatic molecular dynamics using full multiple spawning (FMS). Jiahao currently also sings tenor in the MIT Chamber Chorus and Tanglewood Festival Chorus of the Boston Symphony Orchestra.
