Project: Analysis and detection of differential isoform expression and splicing dysregulation events from RNA-seq data
|University of Sheffield
Max Zwiessele was born in Esslingen, Germany, in 1988. He studied Bioinformatics at the University of Tübingen, and obtained his MSc in 2012 working on probabilistic modelling of Microbiological data using Gaussian processes.
I am working on a probabilistic model, called Baysian GPLVM (Gaussian Process Latent Variable Model). It is a probabilistic interpretation of PCA (Principal Component Analysis), allowing for non-linear mappings for regression or dimensionality reduction. Probabilistic modelling of genomic traits allow for inclusion of different sources of data, which will help to improve predictive performance of mapping molecular traits to observed phenotypes.
My goal is to develop a unifying probabilistic model for continuous and discrete data, which is able to include structural and hierarchical information about biology. I am using Bayesian GPLVM to accomplish this task, because of its unique features discovered in the past. It is capable of taking advantage of structural information such as time dependency (Damianou et al.) or taking unknown environmental perturbations into account (Fusi et al.).
All my implementations are publicly available on Github in the Gaussian process toolbox GPy (Github). I am a developer on the framework, implementing dimensionality reduction tools using probabilistic models.
I am organizer in the Gaussian process summer school held every half year in the University of Sheffield (GPSS). If you want to learn more about Gaussian processes or are a beginner and want to start using GPs feel free to participate. It is a great opportunity and will help you understand Gaussian processes more.
Motivation for participating in the network
Personalized medicine is becoming a big part in the healthcare of humanity. Personalized medical care tailored to each individual will bring a more healthy future with higher accuracy in curation of all ailmends and less drug usage.
