My commitment to promoting diversity and inclusion in academia is grounded in my personal experience from research and teaching. I have fruitful collaborations with underrepresented minority (URM) colleagues, resulting in over 20 joint publications, and many NIH funded grants. At Washington University in St. Louis, I am a faculty mentor of the NHLBI funded Programs to Increase Diversity among Individuals Engaged in Health-Related Research (PRIDE). Through this program I help promote the research capability of the junior URM faculty members, in particular the grant writing skills. I will continue to pursue efforts to enhance diversity, equity and inclusion
