Many date ranges end in 'present'. At this very moment he resume states that he is:
Chief Technical Officer, SEC Biotechnologies
Research Specialist, Center for Experimental Therapeutics
Research Associate, Office of Health Services Research
Co-Principal Investigator, Data and Statistics Core, Center for Health Equity Research and Promotion
and the most modern language he lists on his resume is C.
Something looks fishy. I don't believe this guy has been hands on since the early '80s.
