"[...] Yan did an absolutely brilliant job. He has multiple skills and qualities making him a great data science project member, and even leader : excellent knowledge and learning ability of diverse statistical and data management tools obviously, and a real knack for data viz."
"Yan always performed with outstanding skills and impressive capacity for adaptation and efficiency. His job was crucial for the publication of important results. [...] I thus highly recommend him for any work concering framing and analysis of huge data sets."
"Yan has taught me everything I know about data visualization! He taught my group how to display data in clever ways, and has been responsible for our recent interactive website related to psychiatric epidemiology.
Also, he is a super-fast and efficient bioinformatician. He has set up a pipeline to handle large genetic datasets and apply modern analytic methods to explore the genetic architecture of traits and disorders.
He is a super-bright guy – I can highly recommend him!"
