Andre Francis Palmer is an American engineer who is the Associate Dean for research in the College of Engineering and the Fenburr Ohio Eminent Scholar and Professor of Chemical and Biomolecular Engineering at Ohio State University. He is an expert on hemoglobin-based oxygen carriers and biomaterials used in transfusion medicine.




Biography


Palmer was born in Port of Spain on the twin island Republic of Trinidad and Tobago. He is fluent in English and became a U.S. citizen. Palmer earned a chemical engineering degree at Howard University in Washington D.C in 1993 and his doctorate in chemical and biomolecular engineering at Johns Hopkins University in 1998.
After completing postdoctoral work at Johns Hopkins University in 1999, Palmer joined the Chemistry Department faculty at Howard University. In 2001, he left for the University of Notre Dame to become assistant professor of chemical and biomolecular engineering. In 2006, after five years, he moved to Ohio State University to become associate professor of chemical and biomolecular engineering, and was promoted to full professor in 2012. He served as interim department chair in 2014–2015. In 2015, he was named Chair of the William G. Lowrie Department of Chemical and Biomolecular Engineering and served until 2019.
In March 2020, the Ohio Board of Regents named Palmer, "Ohio Eminent Scholar," a statewide endowed chair. In August 2021, Palmer was appointed Associate Dean for research, charged with directing the College of Engineering's $138 million research enterprise.

As of 2022, Palmer has four active RO1's from the National Institutes of Health for bioengineering research projects. He has multiple collaborations from research labs across the U.S.
In 2021, Palmer received the Gaden Award from the Biotechnology & Bioengineering (journal) in recognition for a truly outstanding paper.
In 2015, Palmer was inducted fellow of the American Institute for Medical and Biological Engineering "for pioneering advances in engineering novel hemoglobin-based oxygen carriers for use as red blood cell substitutes in transfusion medicine."
In 2008, Palmer received the Lloyd Noel Ferguson Young Scientist award from the National Organization for the Professional Advancement of Chemists and Chemical Engineers (NOBCHE).
In 2001, Palmer was a recipient of the National Science Foundation CAREER Award for "engineering artificial cells.”




Research


Bridging the fields of chemical engineering, biochemistry, and biomaterials, Palmer's research focuses on the biophysical properties of hemoglobin, blood and plasma substitutes, and novel methods in protein purification, including interactions between adjacent cells
Palmer currently holds several patents on his work.

Hemoglobin-based oxygen carriers (HBOCs)
Palmer's lab identifies new ways to build HBOCs. Their design strategy focus on increasing the molecular diameter of HBOCs so they're unable to traverse across blood vessel walls into the tissue space and limit negative side-effects.

Detoxification of Hemoglobin(Hb), Heme and Iron
Palmer's lab developed a hemopexin mimetic apohemoglobin (apoHb) that can scavenge heme, and when bound to Hp as the apoHb-Hp complex can scavenge and detoxify both heme and cell-free Hb.
