Industry Keynote Session

S. David Roh is the Chief Technology Officer of LG Innotek. He oversees the R&D and technology strategy for advanced optoelectronic devices, laser modules, 3D sensing and semiconductor packaging. With expertise in III–V semiconductors and photonics, he has been at the forefront of driving innovation in next-generation optical technologies.

Roh earned his BS and PhD degrees in electrical and computer engineering from the University of Illinois at Urbana-Champaign. After gaining experience in the U.S. semiconductor and photonics industry, working at Agilent Technologies, Photodigm, and Coherent, he joined LG Innotek in 2010. Since then, he has advanced through leadership roles, being named LG Innotek Fellow in 2010, promoted to Senior Fellow and Vice President in 2019, and later to Senior Vice President in 2023.

In particular, he led the development and commercialization of the world’s first 3D sensing laser module for mobile devices in 2017, contributing to advancements in smart device sensing technology. He is also an Institute of Electrical and Electronics Engineers (IEEE) Senior Member, contributing to the academic and industrial progress of optoelectronics and sensing technologies.

As BP’s Chief Chemist and VP for University Partnerships, Cathy Tway advances BP’s innovation portfolio. She has held leadership roles at Johnson Matthey and Dow before joining BP. Tway excels in developing technologies, scaling processes, commercialization, licensing and supporting catalytic systems. Over her career, she commercialized two new inorganic materials and four catalysts, with two processes still in operation today. She advises the InNegev technology incubator and is on the Governing Board for the International Centre for Advanced Materials.

Tway often participates in review panels, boards and committees, including those for the U.S. Department of Energy and the National Academies of Sciences, Engineering, and Medicine, where she is a member of the Chemical Sciences and Technology Board. Recently, she was named a Fellow of the Institute of Materials, Minerals and Mining for her contributions to inorganic materials science. Tway holds a PhD degree in physical inorganic chemistry from the University of Nebraska.
