BIO
Co-founder & CEO of Perseus Defense. I helped lead major parts of the NASA Titan Dragonfly space helicopter. I also secured half a million of NASA HQ funding to lead an advanced concepts team using AI/ML/supercomputing to design next generation Mars helicopters. I teach aerospace engineering at Stanford, fly airplanes, have 7 scuba certifications, and speak four languages. I wrote a book in four months last fall, "Dare to Dream: A Small-town Kid's Journey to NASA."
