I am a Ph.D. Candidate in the Department of Chemistry at Emory University (Computational physical chemistry division).
I am currently working in
Professor Kindt's Group. ( Expected to graduate in January 2016 )
I got my B. S. degrees in University of Science and Technology of China.
Major degree: Chemistry & Physics; dual degree: Economics & Finance
Molecular dynamic simulations, rare-event simulations and Monte-Carlo simulations.
Statistical data modeling for equilibrium constants in non-ideal systems.
Understanding the permeation rate anomaly in lipid phase transition.
liposome technology, anti-cancer drug design.
Research assistant at Emory University (2010 - Present) Details: click here
Developed a five-site Lennard-Jones membrane model to study the permeation rate anomaly of membranes during its phase transition,
and proposed a new explanation in terms of line tension (using Perl).
Applied umbrella sampling and probability-weighted histogram analysis methods to a known lipid model together with self-designed parameters of a large permeant,
and tested the assumption of line tension effect. (Ongoing: using Python).
Implemented a variety of known methods in defining the order parameters of a molecule, using either cartesian or spherical harmonic coordinates (using Perl).
Estimating the probability of rare events: proposed ways to set up simulations using novel probability weighting methods.
Setting up 2d probability-weighted-distribution method to construct the free energy surface of the translocation of a sodium ion through lipid membranes,
with which the calculation error is decreased by 80% (using C and Labview).
Developed a model to calculate the theoretical signal strength of the sum frequency generation
of two laser beams at gold surface (using Mathematica and Labview).
Project at Dalian Institute of Chemical Physics: The study of Partial Wave Resonances in the F + HD Reaction.
Dissertation thesis: the study of conglomeration and the electrochemistry behavior after carbon nanotube reacts with potassium permanganate.
Dual dissertation thesis: Visualization of the correlation between monetary policy and stock price for different industries, using first-difference estimator.
