In 2003, Stephan worked at Translational Genomics Research Institute (TGen) as a Senior Investigator and founding Chairman of the Department of Neurogenomics. He later served as the Deputy Director of Discovery Research at TGen. His laboratory has identified the genetic basis of 20 single gene disorders, and several dozen complex genetic disorders using high-throughput technologies and strategies, many if which were developed by his team
He served as tenured full professor and Chairman of the Department of Human Genetics at the University of Pittsburgh from 2013 to 2018.
He has also implemented personalized genomic medicine clinical programs with sustainable business models. Stephan crafted the business case and obtained the initial funding for the Gene Partnership Project at Children's Hospital Boston and Harvard Medical School.

He held faculty positions at the Children's National Medical Center and Johns Hopkins University.
Stephan has published more than 150 peer-reviewed scientific articles in the scientific literature, in top tier journals such as Science, New England Journal of Medicine, Cell, and Proceedings of the National Academy of Sciences.
He served as the Chairman of the NIH Neuroscience Microarray Consortium for seven years. This was at the time the highest volume genome scanning infrastructure in the world, performing the International Autism Genome Project and the largest study in ALS (Lou Gehrig's Disease), among others.

## Business career

Stephan co-founded Navigenics, a personal genetics testing company, with oncologist David Agus, which was among the first direct-to-consumer genomics company (acquired by Life Technologies).
In January 2007, bases on a publication from his group in Science, he co-founded Amnestix, a pharmaceutical company that focuses on the treatment of learning and memory impairment, acquired by Sygnis AG. In 2009, together with Vern Norviel, he co-founded Aueon, Inc., a biotechnology company that invented and patented tumor sequencing and targeted therapeutic selection for cancer patients which is now emerging as the standard of care in oncology.
In 2011, he founded a next-generation genome sequencing and interpretation company, Lifecode (acquired by MedGenome).
In 2014, he helped found Pendulum therapeutics and served at its Chairman of the Board until 2018. Stephan has served at Chairman of the Board of Peptilogics, a rational peptide therapeutics development company since 2015.
In 2019, he founded NeuBase Therapeutics, a biotechnology company focused on developing antisense therapy.
