Congratulations to Mario Otto, MD, PhD, who recently won a 2016 American Association of Immunologists (AAI) fellowship. The AAI Careers in Immunology Fellowship Program supports the career development of young scientists by providing eligible Principal Investigators with one year of salary support for a trainee in their labs. This year, Dr. Otto was one of 48 members selected to receive AAI Careers in Immunology Fellowships, which provides independent research scientists with fellowships supporting one year of salary for a trainee (pre-doctoral or postdoctoral) in their labs. Consideration for award is based on the merit of the PI's proposed project, potential of the trainee, and the quality of the training environment. The award to Dr. Otto will support Kyle Kloepping, PhD, for the project entitled, "A Novel Phospholipid Ether Analog to Combine Targeted Molecular Radiotherapy and Immunotherapy in Pediatric Solid Tumors."
