Cheikh Cisse

Biography

Dr. Cheikh Cissé is an aerospace engineer, research scientist, academic and author. His training and work experience place him at the intersection of high-tech industry and academia, with expertise in turbomachinery, structural design, mining and materials science. He is currently a senior propulsion engineer at Boeing and an adjunct professor in the College of Aviation at Embry-Riddle Aeronautical University. 

Dr. Cissé is known for his cutting-edge scientific contributions to the characterization, multiscale modeling and design of multifunctional materials such as shape-memory alloys, nanocomposites and ceramics, piezoelectric materials and aerospace composites. His works utilize novel computational methods and robust implementation schemes to understand, connect and improve the deformation mechanisms, microstructure evolution and properties of these materials at different length scales. This helps accurately design smart, adaptive and self-healing structures/systems and sustainable energy harvesting devices. He has written, co-authored and peer-reviewed many scientific articles. His research works have been published in peer-reviewed journals such as Science, International Journal of Plasticity, Acta Materialia, Journal of Intelligent Material Systems and Structures, International Journal of Solids and Structures, Computational Materials Science, International Journal of Mechanical Sciences, Materials & Design, Mechanics of Materials, Journal of the European Ceramic Society, Behavior and Mechanics of Multifunctional Materials and Composites and Smart Materials and Structures.

Dr. Cissé is the author of the book "Pour Une Révolution Industrielle et Minière en Afrique" [French Edition]. In this manuscript, he diagnoses the economic, political and social challenges of Africa's mining industry. He discusses the unfair contracts, the corruption, the pollution and environmental problems, the lack of commitment of local governments and the absence of local investors. He also depicts the origins of the low industrial impact and output of African countries despite their huge mineral assets. Ultimately, he proposes multiple solutions to help improve the economy of the continent and create jobs for millions of young Africans via a better use of the mineral resources and an intensive industrialization.

Professional Experience

INDUSTRY CAREER

Dr. Cheikh Cissé started his Aerospace career at Honeywell Aerospace, where he worked on the development programs of various propulsion products such as turbofans, turboshafts and Auxiliary power unit (APU). As the focal point and Tech Lead for foreign object debris/damages (FOD), he was responsible for developing predictive tools for engine damage and performance loss induced by forced response and/or impacts of bird, ice pieces, blade parts and rotor burst. He developed various models to capture bird strike into jet engines, and led projects such as rig facility development to ensure the fulfillment of pre-flight engine certification. Later, Dr. Cheikh Cissé joined Boeing as a senior propulsion engineer. His propulsion and aviation expertise includes

• Ensuring that engine design meets FAR § 33.76 (bird ingestion) and FAR § 33.77 (ice ingestion) requirements;
• Developing bird and composite material models to improve the simulation accuracy and avoid certification test failure;
• Proposing and managing collaborative projects with universities and research centers.
• Conducting FOD sensitivity analysis to influence the design of jet engine components (fan/rotor blades and vanes/stators).
• Providing FOD mitigation strategy for preliminary design review (PDR) and detailed design review (DDR).
• Investigating abradable damages of engine casings due to load transfer from fan to booster rotor, and blade tip deflection.
• Leading root cause investigations of mechanical failures in fans, compressors, and nacelles.
• Selecting appropriate disposition, design and/or fabrication changes to enable rapid and safe resolution.
• Developing new processes and conducting tests to collect validation data for modeling methods.

ACADEMIC CAREER

Dr. Cheikh Cissé was a Post-doctoral Researcher and Research Associate at the Colorado School of Mines, where he participated in the discovery of a highly efficient and eco-friendly elastocaloric cooling material. While typical elastocaloric materials used for solid-state cooling show a degradation in cooling behavior after hundreds of cycles, laser melting allowed the team to create fatigue-resistant nanocomposite microstructures that can cycle, with consistent cooling capacity, a million times. He also advised and guided graduate students in their research projects. He developed a research proposal that received $470k from the United States Department of Energy to study the multiscale defect formation and domain switching behavior in functional oxides. Likewise, he obtained a $390k research grant from the National Science Foundation to investigate the significant enhancement of structural integrity of shape memory ceramics in high cycle fatigue. Furthermore, he also participated in other research proposal developments to raise funds from agencies such as NASA and DARPA.
