I have a mixed background of experimental and computational biology.
During my Ph.D., I have generated over 300 Illumina libraries for small RNA-seq, RNA-seq, ChIP-seq, GRO-seq, and Genomic sequencing from genetically engineered Drosophila and mice. In the meanwhile, I developed computational pipeline for their analysis.
More recently, I have been interested in writing server-side code with Go.

Using Experimental and Computational Strategies to Understand the Biogenesis of microRNAs and piRNAs
In 2008, I joined the Lab of Dr. Zamore to pursue my Ph.D in Biomedical Science to study the biogenesis of small RNAs (including microRNA and piRNA). Since then I have been leading or co-leading 3 experimental-computational hybrid projects—which were published on Science, Molecular Cell, and Current Biology— and 2 computational projects that were published in Nucleic Acids Research and Bioinformatics. The main approach I used in those projects is the combination of next generation sequencing and computational analysis. I have experience analyzing both the secondary generation sequencing (illumina) and the third generation sequencing data (pacBio) using both state-of-the-art tools as well as ad hoc tools developed in my own hands.
Other than my own projects, I constantly provided bioinformatics support for people in my lab and school, some of these works were published in Cell, Molecular Cell, and EMBO Journal.
