Steven is the Chief Engineer of additive manufacturing (AM) technology development at Northrop Grumman Space Systems. Steven has 15 years of space systems engineering experience including support to the James Webb Space Telescope, and guiding development of precision mechanisms, propulsion subsystems, communications subsystems and composite structures products. Steven currently leads a multidisciplinary team developing, qualifying, and applying additive manufacturing technologies across a wide breadth of NG Space systems products. In more than 10 years of research and development with additive manufacturing, Steven has led advancements in polymers, composites, ceramics and metals technologies at both small and large-scale AM domains. Steven’s efforts led to Northrop Grumman’s first titanium metallic AM part to fly on a spacecraft. Steven also substantially contributed to the creation of robotic thermoplastic composites additive manufacturing capabilities. Steven has also led advancement of design and analysis tools for AM, exploration of in-situ monitoring techniques for additive quality control, development of novel elastomeric printing solutions, and qualification of multiple metallic alloys for fly-away applications. Furthermore, Steven has closely collaborated with many small businesses and universities to help advance their capabilities and the additive manufacturing industry to directly support needs for Aerospace applications and products.
