Postdoctoral opportunity in microRNA functions in single cells

We are looking for two young investigators interested in joining our team as postdoctoral researcher. Our group is part of a larger vibrant international collaborative environment and seeks to address fundamental questions in RNA biology, by applying quantitative approaches such as single-cell RNA sequencing, single-cell proteomics, various high-throughput screening methods and advanced computational biology.

The postdoctoral researchers will develop beyond-state-of-the-art methods to profile the variation of microRNA expression, interactions between microRNAs and their targets, and the impact of microRNAs on the transcriptome and proteome, in single cells.

miRTrace reveals the organismal origins of microRNA sequencing data


Software page:


We present here miRTrace, the first algorithm to trace microRNA sequencing data back to their taxonomic origins. This is a challenge with profound implications for forensics, parasitology, food control, and research settings where cross-contamination can compromise results. miRTrace accurately (> 99%) assigns real and simulated data to 14 important animal and plant groups, sensitively detects parasitic infection in mammals, and discovers the primate origin of single cells. Applying our algorithm to over 700 public datasets, we find evidence that over 7% are cross-contaminated and present a novel solution to clean these computationally, even after sequencing has occurred. miRTrace is freely available at

Friedländer Lab Retreat Gotland 2018

The idea to do a retreat had been growing for some time already and we finally did it this August!

On a rainy Sunday eight members of the Friedländer group made their way to the Swedish isle of Gotland by ferry. Since three new members recently joined the group, the main focus of the retreat was to get to know each other by spending time together in Visby, the capital of Gotland.

Wenjing Kang’s XenomiR study is published in RNA journal!

After analyzing more than 800 public small RNA-Seq datasets, we found the exogenous miRNAs (xenomiRs), e.g. plant derived miRNAs, detected in human samples are more likely to originate from technical artifacts rather than dietary intake. We also performed carefully designed and controlled animal feeding studies, in which we detected no transfer of plant miRNAs into rat blood, or bovine milk sequences into piglet blood.
