Most of my research work focuses on medical and clinical informatics with its use to support healthcare transformation. You can explore my publications either through my google scholar profile or explore them below.
I am also currently a volunteer forecaster in the Good Judgement Project's COVID-19 forecasting study. Additionally, I have created a running calculation of the US death rate (deaths from The Covid Tracking Project) per 1000 people (daily estimation from Census.gov) per year. It is a different way of looking at the impact COVID-19 has had and we can then compare events across time periods. - The COVID Tracking Project just made an update that they are no longer collecting data after March 7th 2021.
