Research Capabilities

Research Capabilities: (1) A Computer Lab for the discovery of novel cancer genes and (2) a Bio-safety Level 2 Biochemistry Lab for experimentally investigating these cancer genes.

Research Interests

  1. We are developing bioinformatics algorithms for identifying potential cancer genes. The algorithms are based on analyzing genetic mutations and gene expression levels in tumor samples. Preliminary versions of the algorithm have identified several novel cancer genes that we are currently validating, experimentally. Two papers based on this research are currently in peer review.
  2. We are using the CRISPR/Cas9 gene editing protocol to investigate the effect of mutations in the cancer genes identified above. Experimental protocols include CRISPR gene editing, cell cultures, PCR, DNA/RNA sequencing, Western Blot, cell viability and proliferation assays, etc. Overall our research includes a broad range of subjects covering genomics, genetics, bioinformatics, identifying genes responsible for cancer and other genetic disorders, biomarker discovery, algorithm design, mathematical modeling, etc.

Biological organisms represent the most complex systems imaginable. Understanding how they function requires the knowledge of biology, chemistry and physics. Our computational biology and bioinformatics group integrates knowledge across disciplines to study biological systems with the goal of understanding the mechanisms underlying diseases.
