Dr. Samrat Sagar

Assistant Professor

Dr. Sagar earned his PhD in Mechanical Engineering from the Indian Institute of Technology Bombay, specialising in musculoskeletal biomechanics, implant design, and structural finite element analysis. He also holds a Master’s degree in Mechanical Engineering from the Indian Institute of Technology Roorkee. His research focuses on biomechanics-driven implant design verification and validation, integrating computational modelling, rapid prototyping, and in vitro testing. His doctoral work involved the quantification of mandible (jaw) biomechanics, with a view to design, validate, and test custom mandibular implants in close collaboration with oral and maxillofacial surgeons. The biomechanical quantification comprised computational and experimental methods to understand the mechanical response of the healthy mandible during activities of daily living and assess its postoperative biomechanics following the use of custom implants.

He presented his research findings at six international conferences, including the International Society of Biomechanics and European Society of Biomechanics Congresses, the apex conferences in the field of biomechanics. Further, he has authored three peer-reviewed articles in prestigious international journals and has published three book chapters in leading forums, alongside filing a patent on the mandible simulator. Before joining DSU, he worked as a Research Associate at the Biomechanics, Orthopaedics and Musculoskeletal Engineering (BiOME) Lab, IIT Bombay.

Dr. Sagar has also contributed to international collaborations, including his research visit to Imperial College London for a project on remote monitoring of upper limb movements for potential applications in tele-rehabilitation. As a Research Associate, he worked with a digital health startup to develop a biomechanical framework to automate rehabilitative physiotherapy. His work has been recognised with the International Society of Biomechanics (ISB) Student Travel Grant (INR 2.2 lakhs) for attending the ISB Congress 2023 in Fukuoka, Japan. During his PhD, he also received support (INR 1.8 lakhs) from the GDC I-NCUBATE program, IIT Madras, for conducting the customer discovery survey investigating the importance of implant customisation. Beyond research, Dr. Sagar has experience in mentoring interdisciplinary teams in medical device development.

Previously, he worked as an Assistant Professor in the School of Mechanical Engineering at Galgotias University, Greater Noida. He also served in leadership roles as a General Secretary at IIT Bombay’s then-largest Hostel, H-15. With his expertise at the intersection of mechanical engineering and healthcare innovation, Dr. Sagar brings a strong vision for advancing biomechanics research, custom orthopaedic implants, and medical device development.
