Dr. Twiner has studied environmental toxicology for over 20 years earning his PhD from Western University (Ontario, Canada). The main focus of his early research career involved identifying and characterizing the toxicological mechanisms of marine and freshwater algal toxins with applications towards the development of molecular and biochemical detection methods as well as assessing the health effects of these toxins on marine mammals and humans. He spent several years working at the National Oceanic and Atmospheric Administration’s Center for Coastal Environmental Health and Biomolecular Research in Charleston, SC before developing his own research laboratory at the University of Michigan. He continued to carry on his research program while completing his medical degree and then residency in Emergency Medicine at Detroit Receiving Hospital, Detroit, MI USA. He is now an attending physician at Detroit Medical Center, Detroit, Michigan.  He holds an academic position with Wayne State University where he continues his algal toxin research but has also branched out to work on research projects involving hypertension and heart failure in the underserved communities within and around Detroit. To date, he has published over 40 research papers.
