I did my medical internship and residency at what is now UPMC Presbyterian in Pittsburgh, PA. I did fellowships in medical oncology at University of British Columbia and hematology/oncology at University of California San Diego. I practiced medical oncology at Harbor UCLA before moving to LA County-USC Medical Center in 1981 to practice general internal medicine and palliative care until 1998. Since 1998, I have been an independent medical researcher/writer. My research interests have been in evidence based medicine and global health. Since 2014, I have been a volunteer collaborator with the Institute of Health Metrics and Evaluation statistically modeling risk factor and health outcome data. Most recently, my interest is in using Intergovernmental Panel on Climate Change data and dietary risk factor data to evaluate the potential effect of global regenerative agriculture on reversing global warming.
