Our research group specializes in life expectancy calculations based on standard actuarial and biostatistical procedures. We apply these scientific methods to data on children born with cerebral palsy (CP), persons in the vegetative state (VS), and to those who have suffered spinal cord (SCI) or traumatic brain (TBI) injuries. We have published extensively on life expectancy, and have consulted on life expectancy in Canada, England, Australia and the United States.
