Current Research Interests

Dr. Ostrovnaya is interested in statistical methods in cancer genomics and proteomics. One of her recent projects involves developing methodology for distinguishing second primary tumors from metastases using point mutations, copy number or next generation sequencing data. Other interests include developing new methods for prognostic modeling using mutation data. Dr. Ostrovnaya is a biostatistician for neuroblastoma group, POETIC clinical trials (Pediatric Oncology Experimental Therapeutic Consortium) and for the bladder cancer group in the Department of Medicine. She is also working with the lab of Dr. James Hsieh.
