GENOMIC HETEROGENEITY IN PRIMARY BRAIN TUMORS

Tumors are highly heterogenous entities that evolve in time under the pressure of treatment or just to survive. We are interested in understanding how the genomic profiles of these tumors change in temporal or spatial dimension, and how these changes affect the response to treatment.

MOLECULAR PRECISION MEDICINE FOR PRIMARY BRAIN TUMORS

Tumors, especially brain tumors with high inter and intra tumor heterogeneity, require personalized approaches for most effective treatments. Deciphering the molecular architecture for each and every tumor is essential for precision medicine efforts to succeed.We are using and developing computational analysis methods to guide the genomic characterization arm of precision medicine efforts at Yale.

BIOINFORMATICS ANALYSIS COLLABORATIONS

We love to collaborate ! Over the years we worked with other labs across different departments on other cancer types, neurodegenerative diseases and clinical research. We will keep working with our colleagues and expand our interests.
