Research Interests 

Nuclear receptor coactivators and cancer 

Research Summary

My research is interested in transcriptional control mechanisms involved in hormone and growth factor signaling. My current projects revolve around AIB1 (amplified in breast cancer 1), a nuclear receptor coactivator found in elevated levels in breast, pancreas and prostate cancer, among others. Of major interest is AIB1’s more potent isoform delta three AIB1, which our lab discovered.
