  • Marcel Agüeros is an associate professor in the Department of Astronomy of Columbia University. His research interest is in observational stellar astrophysics, and specifically in using new data sets and technologies to address classic questions in stellar evolution. He received his Ph.D. from the University of Washington in 2006, came to Columbia as a National Science Foundation (NSF) Astronomy & Astrophysics Post-doctoral Fellow that year, and joined the faculty in 2010. In 2013, Marcel received a NSF Faculty Early Career Development Program (CAREER) award to lead large-scale observational campaigns exploring the angular-momentum content and magnetic activity of Sun-like stars over billion-year timescales.  Marcel has worked on increasing the numbers of women and underrepresented minorities in the sciences since starting graduate school. At the University of Washington, he helped create the Pre-Major in Astronomy Program, through which first-year underrepresented students interested in astronomy are exposed to research, and which now has over 100 alumni. And he help launch and directed the Bridge to the Ph.D. Program for a decade. In 2008, the National Society of Black Physicists awarded Marcel a Certificate of Excellence in recognition of "distinguished personal initiative on diversity in astronomy." In 2016, Marcel received the Presidential Early Career Award for Scientists and Engineers (PECASE) for "his groundbreaking research in stellar astrophysics, and for his restless desire to ensure that minority students in sciences become tomorrow's leaders."

  • Dr. Kwame Osei-Sarfo currently is the Director the Bridge to Ph.D. Program in the Natural Sciences at Columbia University. As Director, he promotes the participation of underrepresented groups in doctoral programs by providing research, mentoring, and support experiences. Prior to this role, Dr. Osei-Sarfo was a biomedical researcher, who studied multiple subfields in oncology at New York University (NYU) School of Medicine, Weill Cornell Medical College, and Innovimmune Biotherapeutics. Also, Dr. Osei-Sarfo has served an educator to students of various backgrounds at John Jay College for Criminal Justice and New York City College of Technology. Finally, he has volunteered with many organizations that promote interest in STEM fields for “nontraditional” high school and college students. Dr. Osei-Sarfo understands the need and the importance of improving and fostering support systems for the next wave of underrepresented STEM scholars.

    Dr. Osei-Sarfo received his B.S. in biology from Xavier University of Louisiana. He earned his Ph.D. in molecular oncology and immunology, by investigating pathways involved in the initiation and development of leukemia & lymphoma, from NYU Graduate School of Arts and Sciences.
