Fang's research focuses on the structure formation in the universe. It is generally believed that all structures in our universe, including galaxies, clusters of galaxies, and quasars, are the seed of initial density perturbations in the very early universe. Recent observations of the temperature fluctuations of cosmic background radiation open a window to directly "see" the primordial seeds in our universe.

My research interest has been in the detection of energetic particles, especially in space. My current interest is in observing space plasma dynamics through the detection of energetic neutral atoms (ENA). Unaffected by magnetic field ENA can travel large distances between their being neutralized and their being detected, thus enabling us to construct spatial distributions (images) of energetic ion populations far away, such as those in the inner and outer heliosphere and those in planetary magnetospheres or ionospheres.

My current research interests include problems in a sub-field of condensed matter physics known as mesoscopic physics, as well as on quantum dynamics in classically chaotic systems, a.k.a. "quantum chaos". In both cases my investigations focus on the relationship between quantum and classical physics. The main studied topics are coherent transport, the mesoscopic proximity effect, and entanglement generation and decohence in dynamical systems.

My research is the field of experimental high energy physics. It is carried out at the Fermilab Tevatron in Chicago (D0 experiment) and the CERN Large Hadron Collider (ATLAS experiment) in Geneva. Both experiments seek to answer fundamental questions in physics using Terascale energies. The D0 experiment studies collisions of 1 TeV protons with 1 TeV antiprotons. We built and maintain several key instruments (L1MU and L1CTK triggers) for this experiment. My physics research is focused on the top quark, the heaviest of the known quarks. Specifically we are measuring the W boson helicity in top quark decays. By comparing our measurement with predictions from theoretical models this effectively becomes a search for new physics beyond the Standard Model. The ATLAS experiment will study collisions of 7 TeV protons with 7 TeV protons beginning in 2008. We are involved in commissioning the CSC muon chambers and writing monitoring software for data-taking. My research is focused on discovering new particles created at this new energy regime. Specifically we will measure the top-antitop quark mass spectrum in order to search for new particles that decay as a resonance in this channel.
