  Dr. Arnab Chanda is an assistant professor at the Centre for Biomedical Engineering, Indian Institute of Technology (IIT) Delhi, India, and a joint faculty at the Department of Biomedical Engineering, All India Institute of Medical Sciences (AIIMS), Delhi, India. He is also the founder of a startup company BIOFIT Technologies LLC, USA. Dr. Chanda is an expert in the area of biomechanics, especially foot mechanics. Dr. Chanda has been studying slips and falls caused due to footwear for more than eight years. He has conducted experiments with more than 100 human subjects, with a range of new and worn footwear, in gait laboratories to study unexpected slips and measure the biomechanical parameters at different stages of slips and falls. Also, he has worked with several footwear traction measurement devices used across the industry, such as BPN and SATRA, for measurement of traction in 200+ footwear designs, and provided consultancy services to footwear companies, such as Nike. Recently, the most advanced footwear traction characterization device, which is also the first portable device, was developed in his with funding support from government and private agencies. This pioneering device is current being used to study traction across footwear in a range of cohorts. To date, Dr. Chanda has been involved in the research of footwear traction as a part of University of Pittsburgh, USA; IIT Delhi; AIIMS Delhi; and Indian Spinal Injury Centre (ISIC), Delhi. He has received young researcher awards from ASME and MHRD, holds 7 US patents and 2 Indian patents, and has authored more than 50 articles in reputed international journals, and his research has been featured in news in Times of India, NDTV, and India West, USA. Currently, Dr. Chanda heads the “Disease and Injury Mechanics Lab (DIML)”, where his team is working on developing cutting-edge technologies to study and improve traction in footwear.   Shubham is a Ph.D. scholar in the Diseaseand Injury Mechanics Lab (DIML). He completed his B.Tech. in Mechanical Engineering from the University of Pune in 2019. His research is focused on the study of traction performance of worn footwear. He was instrumental in the development of the advanced portable footwear traction characterization device and has also experimented with a range of worn footwear to estimate their traction reduction and determine replacement thresholds. Shubham has also developed a pioneering computational fluid dynamics-based (CFD) model to study the underlying physics behind the traction properties presented by a new or worn footwear on slippery fluid contaminated floorings. He also aims to integrate different fields of engineering that would produce impressive technologies to benefit mankind.   Subhodip is a Ph.D. Scholar in the Disease and Injury Mechanics Lab (DIML). He previously worked as an assistant professor at Regent Education and Research Foundation College of Engineering, West Bengal. He has completed his M.Tech. in Metallurgy and Materials Engineering from the Indian Institute of Engineering Science and Technology, Shibpur, West Bengal, and B.Tech. in Mechanical Engineering from the West Bengal University of Technology. His research focus is on the experimental study of barefoot and footwear traction. He has tested a range of footwear-floor-contaminant combinations and studied the science of footwear traction through systematically modifying the footwear tread patterns. His work has been valuable in establishing correlations among footwear tread design, traction, and the incidences of slips and falls.
