Donald J. Johann Jr., M.D. Medical Oncologist

Clinical Biography

As a medical oncologist, I focus on the application of advanced molecular profiling and high-throughput technologies for the characterization of genetic-based alterations in cancer cells. Areas of emphasis include cancer biology and bioinformatics; Next-Gen Sequencing (NGS), high-resolution identity-based mass spectrometry (proteomics) and laser capture microdissection (LCM).

I became a physician as a second career. Prior to medical school, I worked as an engineer for the Sperry/Unisys Corp for six years. Rising through the ranks, I directed a group of five engineers on research and development projects involving systems-level software (OS, compilers), avionic software and instrumentation.
