Translational Bioinformatics in the Age of Data

Billions of clinical measurements are recorded every day and stored in electronic health systems around the world. Each one of these experiments is a window into the human system, creating the most comprehensive and diverse medical data set ever imagined. Unfortunately, traditional statistical techniques were not developed to handle such diversity, instead they excel at analyzing homogenous data sets with first order effects. Because of this, these techniques are simply unable to untangle the sophisticated web of biological pathways and genetic interactions governing the human system.

In our lab we develop the algorithms, techniques, and methods for analyzing enormous and diverse data. We do so by designing rigorous computational and mathematical approaches that address the fundamental challenges of observational data analysis -- namely the lack of controlled exposure conditions. And foremost, we integrate our medical observations with systems and chemical biology models to not only explain drug effects, but also further our understanding of basic biology and human disease.

One particular area of interest is the integration of high-throughput data capture technologies, such as next-generation genome and transcriptome sequencing, metabolomics, and proteomics, with the electronic medical record to study the complex interplay between genetics, environment, and disease.

Medicine Gets Personal

By Aliyah Baruchin

"The information in the chart will be used to shape and guide this patient's care. But researchers such as Nicholas Tatonetti, PhD, assistant professor of biomedical informatics and director of clinical informatics for the cancer center, would like to know more-a lot more." Read the whole story.



Manish Mehta awarded summer training fellowship

Congratulations to Manish Mehta (P&S MD Student) for being awarded a 2014 College of Physicians and Surgeons Summer Research Training Fellowship funded by the NIH. Manish will be working in the Tatonetti Lab to combine his expertise in engineering and mathematics with his training in medicine to model dynamical systems in network pharmacology.
