  • I have also done a fair bit of research in biostatistics during the years 2008-2010 while I was employed by the Center for Outcomes Research (COR) under the department of surgery at UMASS Medical School. You can take a look at the publications below, however, I am no longer active in this area aside from ocassional consulting.
