Justin Vijay Jesudas
Head of operations/Centre Manager, R2D2
Justin Jesudas joins us with over two decades of corporate experience in research and analytics across banking and engineering services industries with companies like UBS, RR Donnelley, and Cognizant. Justin heads the operations and outreach activities of R2D2, apart from guiding the team on user perspectives, prototype refining, and device commercialization.
With 11 years of lived experience as a tetraplegic (paralyzed neck downwards), working in the assistive technologies space was a natural calling for Justin.
He is an international swimming champion representing India at the World Swimming Championship and Para-Asian Games. He enjoys long drives in his modified hand-operated car, beach surfing, and SCUBA diving.

Samson Daniel
Head of operations/Centre Manager, NCAHT
Samson has been an occupational therapist by education and a former tutor and clinical occupational therapist at the Rehabilitation Institute, CMC Vellore, for eight years. At R2D2, Samson oversees the partner dissemination program for Arise Standing Wheelchair and research for TouchFREEDOM, among other projects. He has developed wheelchair cushions, which are now part of IIT Madras, and incubated NeoMotion’s product portfolio.
His upbringing in a service-minded family, interest in DIY projects, and passion for restoring the hand functions of persons with such a need pushed him to a space many therapists overlook - assistive technologies.
He lives in Chennai with his parents and sister. He loves photography, cooking, and long rides on his motorcycle.
