Freelancer and manuscript/paper reviewer, Taiwan Mar 2017 – Now I traveled back to Taiwan since March of 2017 for an emergent family issue and stayed at Taiwan to look after my father who was in end-stage cancer status and escorted him to do kidney dialysis every two days till he passed away. My father died peacefully at last August and I came back the USA around late November after I completed three months of period of mourning according to the traditional culture. During the interval in Taiwan I spent most of my time in caring my father therefore I can only work as a part time manuscript and paper reviewer to keep my studies in Public Health, Translational Medicine, Genomic Science and Bioinformatics and other related fields. My employers are my past colleagues from Taipei Veterans General Hospital, National Yang-Ming University and National Health Research Institute of Taiwan Government.

Position Title: Research Fellow

Job contents: Dry lab analytic work only (for team work & independent projects without subordinates)
Finished “Transcribe_CABG” project which is a cardiac genomics project for comparing the association study outcomes of patients before and after coronary artery bypass graft surgery. The goal is hopefully to identify the functional cis- and trans- elements triggered by ischemia or other surgical conditions. I developed the RNA-Seq QC & Mapping pipline to get the normalized expression dataset to be used to combine our imputed genotyping dataset to finally perform the eQTL and GWAS Catalog co-localization studies to obtain the functional SNP candidates and eQTL gene candidates and compared them with GTEx cardiovascular data. I also anlyzed the differential gene expression between baseline and ischemia states using DESeq2 and HTSeq packages. I did the PEER factor analysis (Probabilistic Estimation of Expression Residuals) to regress out both known and hidden covariates to increase the statistical power and the eGene quantity of our states-specific and response-specific cis-eQTL analyses.
The coding skills and techniques I have developed and learned from this project including the following tools and software packages: RStudio shiny web, PLINK, Impute2, PEER, GSEA, GATK, IGViewer and SNPsnap of Broad Institute, CytoScape, MatrixEQTL, gQTLstats and gQTLBase from Bioconductor etc.
