Research Projects

  • Department of Pediatrics, Division of Immunology and Allergy, UCLA
    Principle Investigators: Talal Chatila, MD, Sean McGhee, MD, Katrina Dipple, MD, PhD

    - Characterized dock8, the gene responsible for autosomal recessive Hyper IgE syndrome, in zebrafish and created a knockout model using morpholino antisense technology. We found ubiquitous expression in early development. Knockout of dock8 resulted in normal rag1 expression, but a dysmorphic phenotype and decreased phox2b expression, revealing a possible role for dock8 in brain development.
    - Funding: Human and Molecular Development Training Grant T32 HD07512 (2010-2012)
  • Tissue Engineering Laboratory, UCLA School of Engineering
    Jerry Weintraub Center for Reconstructive Biotechnology, UCLA Center for Health Sciences
    Principle Investigator: Prof. Benjamin M. Wu, DDS, PhD

    - Defined the engineering design rules for a more controlled printing method of depositing genes, matrix material, and cells, which aid in the fabrication of 3D Tissue Analogs.
