    Gene Utility Model (GUM) is a novel computational pipeline to understand the importance of genes under specific cellular contexts. GUM states that it is the utility of genes that provides selective pressure for the survival and fitness of aberrant cells. Using GUM, it is possible to construct an "utility karyotype" by mapping differentially utilized genes to their respective chromosomal loci. Further, GUM predicts that the resulting utility karyotype can recapitulate, to a certain extent, the chromosomal aberrancies observed in diseases.

    Artificial neural network (ANN) was initially created to model how human brain works. Over past few decades, ANN has evolved into numerous sophisticated algorithms with proven outstanding performance in various recognition tasks. Artificial Neural Network Encoder (ANNE) is a novel weight engineering deep machine learning method that harness the power of autoencoder and demonstrated that it is possible to decode meaningful information encoded in ANN models trained for specific tasks. We applied ANNE on breast cancer gene expression data with known clinical properties as case studies. Our work illustrates the trained autoencoder models are indeed information encoders that meaningful gene-gene associations with numerous supported evidences can be retrieved. ANNE opens a new avenue in machine intelligence that ANN models will no longer perceived as tools to perform recognition tasks but as powerful tools to extract meaningful information embedded within the sea of high dimensional data.

    PERsonalized MUtation evaluaTOR (PERMUTOR) is a novel computational pipeline which collects potent disease gene cooperative pathways to envision individualized disease etiology and therapies. Our algorithm constructs individualized disease networks and modules de novo which enable us to elucidate the importance of mutated genes in specific patients and to understand the synthetic penetrance of these genes across patients. Individualized module disruption enables us to devise customized singular and combinatorial target therapies which were highly varied across patients demonstrating the need for precision therapeutics pipelines. As the first analysis of de novo individualized disease networks and modules, we illustrate the power of individualized disease modules for precision medicine by providing deep novel insights on the activity of diseased genes in individuals.

    GEDI (Gene Expression Dynamics Inspector), developed by Dr. Ingber's Lab, is a computational program that opens a new perspective to the analysis of transcriptome data. By treating each high-dimensional sample, such as one transcriptome experiment, as an object, it accentuates and visualize the genome-wide response of a tissue or a patient and treats it as an integrated biological entity. GEDI honors the new spirit of a system-level approach in biology and unites a novel holistic perspective with the traditional gene-centered approach in molecular biology.

  • Pathway Modelling and Simulation  Pathway Simulation

    One of the most commonly used approaches to model biological systems is that of ODEs. In general, a differential equation can be used to describe the chemical reaction rate that depends on the change of participating species over time. The temporal dynamic behavior of molecular species in the biological signaling pathway network can be captured by a set of coupled ODEs.
