Short Bio

Assistant Professor of Quantitative Biology with an academic career producing broad and cross-disciplinary research and learning opportunities. I am a versatile and effective investigator and educator with proven cross-disciplinary leadership expertise. Over the course of my career I have merged data and information from multiple experimental and quantitative fields of science (e.g. quantitative biology, bioinformatics, evolution, virology, cancer, and analytical chemistry) to identify key problems, develop novel hypotheses and lead cross-disciplinary projects. My current research focuses on quantitative biology approaches to study viral and cancer immunity. Throughout my professional and academic careers, I have consistently driven myself to meet challenges and achieve goals. As a highly motivated, results-driven individual, I offer my organization decisive leadership, dedication, and a commitment to excellence.

Research Interests

– UNIVERSITY OF MINNESOTA, USA
Assistant Professor of Quantitative Biology at the Department of Biochemistry, Molecular Biology and Biophysics, Masonic Cancer Center, and Institute for Molecular Virology, 2015 – Present
• Develop computational biology approaches to uncover the molecular mechanisms of viral/cancer mutagenesis and evolution (e.g. methylation, APOBEC).
• Employ translational bioinformatic methods to discover the link between genomic and transcriptomic variations in human immune genes and determinants of viral control.
• Develop computational pipelines to quantify tumor and tumor microenvironment gene expression profiles.
• Apply quantitative genomics to reveal the role of endogenous retroelements in human evolution and cancer.

– SCHOOL OF MEDICAL SCIENCES, UNIVERSITY OF NEW SOUTH WALES, AUSTRALIA
Fellow of the Australian National Health and Medical Research Council, 2009 – 2014
• Developed interdisciplinary research directions involving computational analysis of host/pathogen interactions.
> Hypermutation signature: Role of RNA/DNA editing by APOBEC and ADAR in the evolution and inactivation of exogenous retroviruses (HIV, SIV, and HBV) and endogenous elements (ERV, LINE, and SINE)
> MHC signature: Role of major histocompatibility complex alleles in viral escape
> CpG depletion signature: Role of CpG methylation, host mimicry and TLR recognition in CpG depletion
• Developed two open access bioinformatic tools:
> HYPERSIGN: Comparison and classification of mutated sequences without alignment.
> G2A3: Analysis of multiple alignments containing complicating indels.

– SCHOOL OF CHEMISTRY, UNIVERSITY OF NEW SOUTH WALES, AUSTRALIA
Postdoctoral Fellow at the Chemometrics and Metrology Research Group, 2007 – 2009
• Developed a new research direction involving analysis of high dimensional and complex data using techniques such as principal component analysis (PCA), partial least squares (PLS) and parallel factor analysis (PARAFAC).
