Department of Biostatistics Announcement

February 6, 2017

Dear Colleagues,

I am delighted to announce the appointment of Joseph W. Hogan, ScD as chair of the Department of Biostatistics effective July 1, 2017.  Professor Hogan will succeed Constantine A. Gatsonis, PhD who became the inaugural chair of the Department of Biostatistics in 2011, having come to Brown in 1995 to lead the development of biostatistics in the then Department of Community Health. Professor Gatsonis will be stepping down as department chair, but will continue to lead the Center for Statistical Sciences.
Professor Hogan came to Brown in 1995 shortly after completing his doctoral work at Harvard.  During his tenure at Brown, he has held several academic leadership positions including, most recently, associate dean for faculty affairs at the School of Public Health.
Professor Hogan’s research focuses on the development of statistical methods for missing data and causal inference. He has a long-standing interest in HIV and AIDS and holds leadership positions in the AMPATH Consortium and the Providence-Boston Center for AIDS Research, and co-directs a partnership with Moi University in Kenya focused on building research capacity in biostatistics. Professor Hogan is a Fellow of the American Statistical Association, is co-author of over 100 peer-reviewed articles, and has served extensively on University, government, and professional society committees.
Professor Constantine Gatsonis has been a driving force in the development of the Department of Biostatistics and the School of Public Health.   He has been an integral member of our leadership team and I personally wish to thank him for his guidance over the years that I have known him. Throughout his career at Brown, he has raised the profile of biostatistics, developing and leading a Center for Statistical Sciences, a section of biostatistics, and then the Department of Biostatistics. 

Vince Mor, professor of health services, policy and practice has known Professor Gatsonis since his arrival at Brown and added that “Constantine was the biggest advocate of the creation of a School of Public Health and for the establishment of an academic Department of Biostatistics. He built the infrastructure, hired the faculty, set up the graduate programs, and expanded the agenda of biostatistics at Brown such that the young Department is on everyone's radar as a high quality place for advancing the science of biostatistics.”

In addition to his invaluable contributions in developing the School of Public Health, Professor Gatsonis is a leading authority on the evaluation of diagnostic and screening tests and evidence synthesis for diagnostic accuracy studies.  He has also made major contributions to the development of methods for medical technology assessment and health services and outcomes research.  Professor Gatsonis co-founded the American College of Radiology Imaging Network (ACRIN) in 1999 and is now a Group Statistician for the ECOG-ACRIN collaborative group, a National Cancer Institute-funded collaborative group conducting multi-center studies across the spectrum of cancer care.  He is lead statistician for several major national studies of screening for cancer, including the upcoming TMIST trial of breast cancer screening.
Our Department of Biostatistics is a vibrant unit of the School and the broader University, with established national and international presence in biostatistics research and education, and an integral component of the University’s Data Science Initiative.  Professors Gatsonis and Hogan are key architects of this success.  I hope you will join me in congratulating Professor Hogan on this new appointment and thanking Professor Gatsonis for his leadership of the Department of Biostatistics.
