Work History

Postdoctoral Research Fellow

University of California, Berkeley
Berkeley, CA
05.2024 - Current

PI: Dr. Niren Murthy, Bioengineering Department.

  • Design, synthesis, and screening of novel ionizable lipids for mRNA delivery to develop safe and effective mRNA vaccines.
  • Synthesis of zwitterionic polymers for delivering RNA therapeutics, with reduced toxicity.

Postdoctoral Research Fellow

National Cancer Institute (NCI/NIH)
Frederick, MD
09.2021 - 05.2024

PI: Dr. Joel Schneider, Chemical Biology Laboratory.

  • Solid-phase synthesis of beta-sheet-forming peptides, peptide macrocyclization, and bioconjugation reactions to modify peptides with fluorescent probes, small molecules, and oligonucleotides.
  • Evaluation of self-assembling properties of beta-sheet-forming peptides and formulation for self-supporting peptide hydrogels.
  • In-depth study on the effect of noncovalent and covalent crosslinking in peptide gels to modulate a broad range of gels' properties, such as enhancing mechanical rigidity, cell viability, diffusion, and the release rate of encapsulated molecules.

Graduate Research Assistant

Carnegie Mellon University
Pittsburgh, Pennsylvania
08.2016 - 08.2021

PI: Dr. Bruce Armitage, Chemistry Department.

  • Synthesis and purification of cell-penetrating peptides (CPP) and mitochondria-targeting signaling (MTS) peptides to conjugate them with antisense PNAs for targeting mutated genes in mitochondria.
  • Evaluation of binding capability of complementary oligonucleotides, such as PNA, to biologically important sequences that form secondary structures like G-quadruplexes and intercalated motifs.
