EXPERIENCIA LABORAL

Post-Doctoral Research Fellow., Massachusetts General Hospital, Harvard Medical School
( 2017 - 2018 )
Conducting research on: In-vivo and in-vitro human hip and knee kinematics, kinetics, and biomechanics before and after total joint replacement using a combined CT based modeling and dual fluoroscopic imaging system (DFIS) approach, as well as a testing cadaveric joint system composed of a robotic manipulator and a six-degree-of-freedom load cell. Collaborating with bioengineers, radiologists, clinical fellows, orthopaedic surgeons to design and implement additional experimental characterization of total joint replacement studies. Collect and analyze pre- and post-operative clinical patient data. Developing and evaluating computational models of the hip and knee joint by integrating 3D image data and experimental biomechanics data obtained from the aforementioned in vitro and in vivo experiments and other already-completed experiments. Presenting and communicating results of analyses at group meetings, national and international conferences, and through publication in journals.
Graduate Assistant, State University of New York at Stony Brook
( 2009 - 2016 )
Conducting research on: Kinematic modeling of fingers to find the optimum angles for arthrodesis (joint fusion). Kinematic and kinetic modeling of the upper limb to calculate joint forces and moments generated during hard contact in sports (football). Robotics and modeling for force and torque calculation of human joints under static and dynamic load conditions. Fault Detection and Diagnosis (FDD). Arcing and metallic faults in power distribution systems. Parallel and serial arcing fault location. Overheating, arcing, and connection degradation in electrical receptacles. Wafer manufacturing laser-assisted machining, wiresaw modeling and control. I have thought the following graduate and undergraduate courses: MEC532: Fall 2011, 2012, 2013, and 2014: Vibration and Control (graduate) MEC325/580: Spring 2012: Manufacturing Processes (undergraduate & graduate) MEC411: Fall 2011: Control System Analysis and Design (undergraduate)
Service Engineer, Automotores y Anexos
( 2002 - 2007 )
Responsible for management of Nissan and Renault warranties in Ecuador. Approved and rejected national claim warranties. Directed training to manage Nissan and Renault warranties in all dealerships in Ecuador. Compiled and processed national claim warranties and generated monthly technical and financial reports which were sent to the international factory. Quality Control Inspector. Controlled and monitored repairs and maintenance of Nissan and Renault vehicles. Verified that not only repairs were within technical specifications and reparation standards but also customers? requirements had been satisfied.

INTERESES

My research lies at the intersection of biomechanics, rehabilitation, motion analysis, athletic performance, kinematics, robotics, and machine design. I am especially interested in analyzing human musculoskeletal and neuronal mechanisms in order to develop assistive technology for improved movement performance and quality of life. Personally, I find the development of sophisticated technologies and equipment allowing disabled people to regain normal functional capabilities, fascinating.
