Dr. Annohene is a highly accomplished expert in the development of programs/projects in process development and optimizations, digital transformation and analytics, experimenting and simulating semiconductor logic and memory devices, and research and development of novel nanomaterial technologies. He has experience in development, synthesis, characterization, and testing of nanostructured materials and devices spanning across the semiconductor, photovoltaics, polymer, biomedical, and food industries.

At Exponent, Dr. Annohene focuses on developing, executing, and managing projects/programs to drive productivity for clients, including process improvement and optimization, quality control and assurance, product development, safety, risk assessment, digital transformation, and data analytics. He also specializes in helping clients develop emerging technologies and improve existing ones through research and development, experimentation, testing, design, prototyping, and commercialization. With his extensive experience using MATLAB, SolidWorks, Python, ANSYS, and many statistical software programs, including SigmaPlot, JMP, and Originlab, Dr. Annohene is well-equipped to tackle any challenge in his field.

With his vast expertise in complex material characterization techniques such as scanning electron microscopy (SEM), x-ray diffraction (XRD), atomic force microscopy (AFM), ultra-visible spectroscopy (UV-Vis), Fourier-transform infrared spectroscopy (FT-IR), nano-indenter, and mass spectrometer, Dr. Annohene is well-equipped to analyze and interpret data from a wide range of sources. He also has extensive experience with thin film deposition equipment, including thermal and electro-beam evaporators, sputtering, and electrospray, which he has used in the development of complex nanodevices.

Dr. Annohene has worked the development and management varied Defense Advanced Research Project Agency (DARPA) programs during his career. He also served as a Process and Analytics Engineering Consultant at International Flavors and Fragrances, where he deployed digital manufacturing tools and executed process improvement programs. Dr. Annohene holds a PhD in the development of perovskite solar cell devices and has patented a novel approach using supercritical fluids in annealing the perovskite active layers to achieve both high-efficient and scalable devices.
