Hansel holds a Bachelor of Science in Radiochemistry (summa cum laude, 2004) and a Master in Science in Radiochemistry (2006) from the Higher Institute of Applied Sciences and Technologies (InSTEC), Havana, Cuba. In 2014 he earned his Ph.D. in Chemistry from the University of Havana, Cuba. His doctoral dissertation specialized on the self-assembly of mesostructured cationic polymer:surfactant systems. Hansel pursued an academic career at his Alma Mater becoming Professor within the Department of Radiochemistry. He also transitioned through two post-doctoral positions at the Italian Institute of Technology (IIT) working on the solar hydrogen evolution by organic semiconductor catalytic systems, and on the optical regulation of living cells by light-sensitive devices based on organic semiconductors. Since 2022, he joined the Hernandez group as Scientist I within the Department of Medical Physics, University of Wisconsin-Madison. Hansel focuses mainly on the development of radiochemistry applications for biomedical research as well as on radiopharmaceutical and radiotheranostic applications for cancer research.
