New paper in Science. Collaborating with the Ecker lab at the Salk Institute we have used computational methods to model Arabidopsis response to stress. The Science paper presents models that allowed our team to identify molecular conductors, top regulators of this response and have also led to the identification of new transcription factors that play a role in plant response to hormone and salt. See the CMU press release for more details.
Best paper award at RECOMB 2016! Our paper 'Shall we dense? Comparing design strategies for time series expression experiments'
has won the 'Best Paper Award' in this years '20th International Conference on Research in Computational Molecular Biology (RECOMB)'. RECOMB

published in the Journal Cell Systems, accompanied by a
We received a large grant from the PA Department of Health to improve the usage of 'Big Data' for cancer . The grant will establish a new center, Big Data For Better Health (BD4BH) which will be co-directed
by Bar-Joseph and Greg Cooper from the University of Pittsburgh. The main focus would be on developing better methods for integrating, analyzing and modeling large volumes of diverse data on cancer patients.
The goal is to produce more accurate predictions of patient outcomes and to enable clinicians to tailor care
for each patient. See the press release from CMU for more details.

Neuroscience-based algorithms make for better networks. A new paper we published in PLoS Computational Biology shows that the methods used by the brain to optimize the topology of neural networks (termed pruning) lead to effective and robust computational networks as well. As part of this work, we have experimentally characterized the pruning rates in developing mice and showed that using similar rates to construct computer communication networks improves their ability to efficiently route messages. This paper further expands the set of Algorithms in Nature we have been working on for the last 5 years. The work has been highlighted by a CMU press release , a press release from the Salk Institute, and a few other venues (for example, Tech Times )
Ercument Cicek accepts new faculty position. Ercument, who is a postdoc in our group since 2013 (also a Lane fellow co-advised by Kathryn Roeder) has accepted a faculty position in the Computer Science department at Bilkent University, one of the leading research universities in Turkey. We wish him good luck on this exciting new appointment!
CACM publishes a new paper from our group. Communication of the ACM (CACM), the top and most widely read computer science journal publishes a paper we wrote on biological distributed computing as the cover story for their first issue of 2015. The paper summarizes several recent studies by us and others in this area. With the success of the BDA workshop we recently organized it seems that this idea is catching up and more and more people are looking into biological systems to gain insights into the design of complex distributed networks and systems. See also an interview CACM recorded with co-author Saket Navlakha discussing the area and the paper.
Three group members accept new faculty positions. Current group members Saket Navlakha (postdoc MLD) and Xin He (Lane fellow and postdoc, co advised with K. Roeder) and former group member Tony Gitter (PhD 2012) will start as Assistant Prof. in the Fall. Saket is joining the Salk Institute for Biological Studies in San Diego. Xin will join the Human Genetics department at the Universtiy of Chicago and Tony will be joining Department of Biostatistics & Medical Informatics and the Morgridge Institute for Research at the University of Wisconsin, Madison. The diversity in terms of types of the departments each is joining indicates the growing importance of computational biology across areas ranging from basic science to clinical studies to statistics and computer science. Congratulations and good luck to all!
Yeast networks provide insights for improving computational network security . In a new paper in the journal Proceeding of the Royal Society Interface we discuss how lessons from yeast and other biological networks can be used to design and evaluate secure communication networks. The work has been highlighted by a CMU press release and a few other venues ( dataconomy , Campus Technology )
SDREM selected as a top systems biology paper. The RECOMB/ISCB Conference on Regulatory and Systems Genomics, selected the Top Ten Papers in the field of Regulatory and Systems Genomics for 2013. We were happy to see that our SDREM paper, that appeared in 2013 in Genome Research is part of that list. Congratulations to Tony!
ExpressionBlast mines large expression datasets. We report in a new paper in Nature Methods on a new web based tool, ExpressionBlast, that can be used to compare expression experiments, within and across species, to hundreds of thousands of arrays deposited in large databases. The tool provides an easy to use GUI and has already been used to successfully study improtant mammalian genes. ExpressionBlast is available online with documentation and support. See the CMU press release and CMU's front page coverage. The method was also highlighted by a number of news outlets including Bio-IT World.
mirDREM reconstructs development and disease networks. A new paper by Lane fellow Marcel Schulz was just published in the Proceedings of the National Academy of Science (PNAS). The paper introduces a new method for reconstructing dynamic regulatory networks that are co-regulated by transcription factors and microRNAs. The paper was featured on the cover of PNAS. In addition, PNAS published a very nice commentary explaining the importance of the method and application. The paper has also been highlighted in a number of news outlets including Nature's SciBX and GenomeWeb . The method can be downloaded from the supporting website.
