I did my PhD in the field of Cancer Biology employing NGS tools(publicly available) or ad-hoc development and analysing them. Mostly I do benchmarking of tools till I find the best fit for the heterogeneous cancer data. I work on integrating multi omics data and slowly now am venturing in field of single cell which is pretty interesting to me as of now. Battling with two of my worst fears Biology and computer science to give life a better meaning. My first fear made me push to get the PhD and now I want to drive the improvements in the field. The challenge in life science and technology drives me and so I am pursuing the research field. Everyday is a new learning and knowledge is never ending. Biostars helped me learn all along and now with my experience and learning am happy to help others. 

Creating automated pipeline scripts for easy usage of different seq technologies.

I am interested in Precision and Personalized Medicine and would like to use my skills in the same with translational NGS technologies for addressing problems related to diseases. Currently working in industry in Omics Drug Discovery.

News: GeNets: a unified web platform for network-based genomic analyses
... A new [tool][1] is up from the Broad Institute. It is named as **GeNets** Just had a look to it today. Seems very comprehensive and wide range of things catering to both network and pathway analysis. Also the tutorials and website have a very aesthetic feel. I would like the community to take a look ...

Comment: C: Noise Analysis for RNAseq Data
... Some pointers: 1. Well you need numbers/replicates first, for each techniques to interpret errors/biases/noises. Do you have that? 2. If so then look for density plot of the data and then go for your threshold to remove genes with zero or low counts depending upon the distribution. 3 ...

Comment: C: VCF SNP analysis
... so if you are trying to find mutations or variants from RNASeq then samtools workflow or STAR/GATK workflow should be fine. I personally like STAR/GATK owing to the statistical model and robustness that you can add to it. Having said that, once you have VCF you can always plot stats to see how many ...

Answer: A: Drug set enrichment analysis
... I would list out [DGIdb][1], probably if you have not come across. Take a look at it. The one of TIGEM is good as well but everything depends on how well the resources are updated.

Comment: C: VCF SNP analysis
... Just to chime in. Please read the structure of VCF and how VCFTools work and what they can do. Then read about SNP and what format of file represent them. Once you read them you can answer your own question. Man page of VCFTool is pretty descriptive. Read and then formulate your query where you get ...
