Research Interest

Metabolomic Profiling of Cancer Progression
Dr. Sreekumar’s research interests are in the areas of biomarker discovery and understanding pathway alterations during cancer development and progression. His work involves the use of high throughput metabolomics platforms as well as system’s based data integration using bioinformatic tools. His metabolomic projects are funded by RO1 and UO1 from NCI as well as funds from Susan Komen Foundation, CPRIT, Department of Defense and Alkek Foundation. The bioinformatics initiative is supported by a grant from the National Science Foundation.

In the area of metabolomics, Dr Sreekumar’s goal is develop multiplex metabolomic markers and biochemical pathways to study cancer development and progression. He was the lead author in paper on metabolomic profiling of prostate cancer that was published in Nature. He has since established an unbiased mass spectrometry-based metabolomic profiling platform to interrogate tumor metabolite. He is currently studying the metabolomic alterations in breast and bladder tumors as an extension of his earlier work on prostate. The workflow incorporates metabolomic evaluation of patient specimens, delineation of class-specific metabolic profiles, functional validation of pathways using invitroa and invivo model systems of the disease and development of non-invasive multiplex metabolic markers for detection and prognosis.

In addition, Dr. Sreekumar is also developing informatics tools to integrate matched OMICS datasets to study cancer progression from a systems perspective.
