Research and Professional Experience
2015.08 – 2018.03 Graduate Student Researcher
Dr. Adam Zlotnick Lab, Indiana University Bloomington, Indiana
Independently designed, purified and characterized a series of Hepatitis B Virus core protein mutants to study antiviral resistance, confirmed a protein mutant has stronger resistance to a core protein directed antivirals.
Applied in vitro biophysical assays (fluorescence, UV/vis, light scattering, size exclusion) to study assembly kinetics and thermodynamics, confirmed hydrophobicity of HBV core protein residue T109 plays an important role in capsid assembly.
Used cell-based transfection system (Hep AD38 cell line) to study core directed antiviral effect and cyto-toxicity with ELISA Assays.
Monitored capsid assembly dynamics in support of nano fluidic experiment with collaborator Lab.
2014.01 – 2015.07 Research Assistant
Dr. Lingling Chen Lab, Indiana University Bloomington, Bloomington, Indiana
Independently designed and purified Chlamydial GroEL1 and GroES chaperonines complex, confirmed chlamydial GroEL1 served as the main chaperonine in chlamydia.
Gained expertise on chaperonine activity of Chlamydial GroEL1/GroES complex via protein refolding assay and ATP binding assay, identified Proline 35 of Chlamydial GroES will affect ATP binding activity and ATPase activity.
2010.07 – 2012.05 Undergraduate Student Researcher
Dr. Donghai Lin Lab, Xiamen University, Xiamen, China
Expressed and purified Raf1 Kinase and Raf1 kinase inhibitor protein (protein).
Tested protein interactions between Raf1 and RKIP via pull-down experiment and other biochemical assays, confirmed weak to medium strength interaction between Raf1 1-147 segment and RKIP by titration assay.
Awarded by Yumiao Undergraduate Scientific Research Fund of the college (4 of 60)
