Steve has over 20 years of nanotechnology experience beginning with his graduate work at Rice University where he discovered a method of fabricating gold nanoshells, a nanoscale composite material that consists of a spherical silica core surrounded by an ultra-thin shell of gold. This discovery led to the formation of Nanospectra Biosciences where the gold nanoshells are in clinical trials as a cancer therapy. After receiving his PhD in Applied Physics, he joined Seashell Technology where he developed commercial applications of nanotechnology, raised capital, and managed the scientific research team. In 2004 he founded nanoComposix to accelerate the commercialization of products based on precisely engineered and highly characterized nanoparticles. He is a co-founder of Sienna Biopharmaceutics and La Jolla Nanomedical, and is on the scientific advisory boards of COLR Security and Optoglo. Steve has 10 issued patents and over 40 papers in the area of nanotechnology.
