About

Alfredo Valverde is a robotics and aerospace engineer whose research sits at the intersection of spacecraft dynamics, robotic manipulation, and advanced mathematical modeling. His work has made significant contributions to the field of on-orbit servicing, an area of growing importance as governments, industry, and academia pursue routine satellite maintenance and repair in space. Valverde is best known for pioneering the application of dual quaternion algebra to spacecraft-mounted robotic systems. By combining rotational and translational information into a single compact mathematical framework, his dual quaternion-based models offer computational advantages over traditional approaches for representing pose, kinematics, and dynamics. His 2018 paper "Dual Quaternion Framework for Modeling of Spacecraft-Mounted Multibody Robotic Systems," built on Newton-Euler formulations, has garnered 33 citations and remains a foundational reference in the field. Complementary works on spacecraft robot kinematics and dynamics and control of manipulators with thrusters and momentum exchange devices — each accumulating over 25 citations — further demonstrate the breadth of his contributions. Across six highly cited publications, Valverde has helped establish dual quaternions as a practical and elegant tool for modeling, control, and estimation in space robotics, equipping future engineers with rigorous frameworks for tackling the complex dynamic challenges of next-generation servicing missions.
