Biography:

2016-Present- Research Associate Professor, Wenzhou Medical University, Wenzhou, P. R., China
Responsibilities:

  • Study the interaction of M. tuberculosis with macrophage.
  • Study the crosstalk between cardiac cells and macrophages Postdoctoral Research Fellow, University of Tennessee Health 

2014 - 2015- Science Center, Memphis, TN
Responsibilities:

  • Screened TB mutants for genes important for its infection using epithelial and macrophage cell lines as in in vitro model and fluorescence labeled glycopeptide antibiotics as a molecular probe.
  • Achievements:
  • Developed a new approach for TB gene screening project and identified several positive hits so far
  • Published one paper so far and are writing the second manuscript Graduate Research & Teaching Assistant Old Dominion 

2008 - 2013- University, Norfolk, VA
Responsibilities:

  • Initiated and implemented the following research projects:
  • Probed the efflux functions of multidrug resistant transporter (BmrA) in different B. subtilis strains including EGFP fused ones by fluorescence spectroscopy and dark-field optical microscopy and spectroscopy (DFOMS) using single nanoparticle optical probes.
  • Constructed, expressed and purified BmrA-EGFP fusion proteins and studied their efflux functions in proteoliposomes by fluorescence spectroscopy.
  • Studied the silencing effects of Ag NPs conjugated with antisense oligonucleotides on the expression of BmrA transporter proteins.
  • Probed the efflux functions of another multidrug resistant transporter (MexAMexB-OprM) in different P. aeruginosa mutant strains by fluorescence spectroscopy.
  • Studied the size-dependent inhibitory effects of Ag nanoparticels with antibiotics conjugated on the growth of bacterial cells aiming to use Ag NPs as potential drug carriers.
  • Expressed and purified different mutant proteins of a multidrug resistant transporter in E. coli (MsbA); probed the catalytic mechanisms of MsbA by farfield photostable optical nanoscopy (PHOTON) using different sized nanoparticle based optical sensors.
  • Studied the nanotoxicity of noble nanoparticles (Ag, Au) using zebrafish embryos as a model.

Achievements:

  • Published three original research papers so far and a couple of more are coming
  • Taught undergraduate courses (biochemistry, analytical chemistry)
  • Obtained my Ph.D. degree
