Christian L. Müller joined the Simons Foundation in 2014 to work at the Simons Center for Data Analysis, developing high-dimensional statistics methods and algorithms with applications to microbial and regulatory networks. He is currently a Project Leader in Computational Statistics. Prior to joining the foundation, Müller held postdoctoral positions at ETH Zurich and NYU. Müller holds an M.S. in computer science from Uppsala University, Sweden, an M.S. in bioinformatics and computer science, as well as a university certificate in literature and poetry, from the University of Tübingen, Germany, and a Ph.D. in computer science from ETH Zurich, Switzerland.
I am interested in developing computational statistical tools that are applicable in data-driven research in biology and microbial ecology.
On the computational side I work on:
- High-dimensional statistics and compositional data analysis
- Black-box optimization and sampling algorithms
- Proximal algorithms and their application in statistics
- Statistical and spectral methods to analyze complex networks
- Statistical tools to describe energy and fitness landscapes
My biological applications include:
- Microbiome data analysis
- Inference of microbial interaction networks from 16S rRNA data
- Analysis of microbial time series data from metagenomics measurements
- Robustness of parameter spaces in biological systems
- Protein conformation spaces and prediction of deleterious mutations in proteins
My CV can be found here (pdf).
I have co-organized a mini-symposium on Proximal Algorithms for High-dimensional Statistics as part of the SIAM Conference of Optimization 2017 which will take place on the 22th-25th of May 2017 at the Sheraton Vancouver Wall Centre, Vancouver. Information and registration can be found here.
We have organized the second workshop on statistical and computational challenges in microbiome research which took place on the 16th-17th of February 2017 at the Broad Institute, Cambridge. Information and registration can be found here (#SACMDA2).
We have organized the first workshop on statistical and computational challenges in microbiome research on the 25th-26th of February 2016 at the Simons Foundation, New York. Further information can be found here.
