- Zhidong Tu works on developing systems approaches to study disease networks. By integrating large scale genomic and genetic information, he has worked on various problems including signaling pathway inference, drug target gene discovery, and biomarker identification. Dr. Tu received his PhD from Computational Biology program at University of Southern California. He then worked in the Genetics group at Rosetta Inpharmatics, a subsidiary of Merck & Co., Inc to study network of genes whose perturbation lead to type 2 diabetes. He later moved to Merck Boston site to work on cancer drug discovery, where the goal was to combine gene expression, sequence variation, drug response, drug-drug interaction to identify most effective medicine for cancer patients.

Systems biology for disease network studyIntegrating and interpreting large scale genetic and genomic data turned out to be a promising approach towards understanding complex disease system. One large goal is to develop novel methods that stitch together various pieces of information to identify the network of genes whose perturbation by genetic variation would lead to disease phenotype. Multiple problems need better solutions:
-Better computational models for data-driven disease network discovery
-Mechanistic interpretation of the link between disease network and phenotype changes
-Systems strategy on disease network rectification and translational research

Physicians and scientists on the faculty of the Icahn School of Medicine at Mount Sinai often interact with pharmaceutical, device and biotechnology companies to improve patient care, develop new therapies and achieve scientific breakthroughs. In order to promote an ethical and transparent environment for conducting research, providing clinical care and teaching, Mount Sinai requires that salaried faculty inform the School of their relationships with such companies.
Below are financial relationships with industry reported by Dr. Tu during 2014 and/or 2015. Please note that this information may differ from information posted on corporate sites due to timing or classification differences.
