The NextStep Robotics team has used their knowledge of robotics and engineering to pioneer a digital breakthrough in the treatment of foot drop and other causes of decreased mobility. Our experienced staff’s creative solution to the rehabilitation of foot drop has changed how orthopedic specialists will treat this condition. Most importantly, our team’s practical high-tech device will improve the quality of life for people who want to regain mobility.

Our Team

Bradley Hennessie


Brad is a former Lead Clinical Research Specialist from the University of Maryland, Baltimore, and is now leading the charge to commercialize this device and provide physical therapists a novel approach to effectively and durably reduce the adverse or potentially adverse effects of foot drop. He has been working with his co-founders for over a decade and has secured significant funding, including a cooperative agreement with NIH National Institute of Neurological Disorders and Stroke.

Richard Macko, MD


Dr. Macko is a neurologist and professor of neurology at the University of Maryland, Baltimore, where he is a leading expert in stroke recovery. Dr. Macko has published over one hundred fifty peer-reviewed research articles in the field of stroke neurorehabilitation. Dr. Macko has over 20 years of experience including as the Director of the VA Rehabilitation Research and Development Center of Excellence in Exercise and Robotics in developing and testing disability and disease specific exercise training models that combine motor learning with exercise rehabilitation including lower-limb robotics to improve functional mobility for individuals with stroke and other chronic mobility disability conditions associated with advancing age. Dr. Macko has extensive experience in successfully obtaining state and federal grant funding.

Anindo Roy, PhD


Dr. Roy is the engineer behind it all, developing the control system embedded in our robotic device that is critical to safe and effective ankle training in the context of walking. With extensive experience and training in rehabilitation robotics at MIT, Dr. Roy has a unique perspective and skillset in translating therapy needs into robotic solutions. Dr. Roy leads all efforts in engineering including integrating robotics into the recovery pathway and generating new intellectual property. Dr. Roy has adjunct faculty appointments in both the University of Maryland school of medicine and in the James Clark School of engineering.

Larry Forrester, PhD

Resident Scientist

Dr. Forrester is the recently retired Director of the Baltimore VA Human Motor Performance Laboratory. Larry has nearly two decades of experience conducting rehabilitation research focused on therapeutic interventions to improve movement function after stroke and other neurological diseases.

Nick Rabuck

Mechanical Engineer

Nick is a mechanical engineer with a passion for design, research, and development of Mechatronics systems. With his family spread out among fields such as Medical, Engineering, & Construction; he has a variety of sources to pull inspiration from while working to design and manufacture the mechanical aspects of rehabilitation robotic systems. Nick is an avid fan of 3D printing, home automation, and video games all using his custom built PC.

DJ Eversley


DJ is a biomechanist who runs our motion analysis lab to provide objective measures of human movement and performance that can be used by our multidisciplinary team of professionals to provide the highest quality patient care. He formerly worked as the lab manager of the Baltimore VA Human Motor Performance Laboratory.

Suchitra Chandar

Control Systems Engineer

Suchitra is a Control Systems Engineer with NextStep Robotics and specializes in firmware development, integration and testing with robotic systems. She has a product development mindset focused on the user and enjoys working in an interdisciplinary team addressing high impact problems. She joined the NextStep family soon after receiving her Masters in Electrical Engineering from Purdue University and also likes to paint and dance in her free time.

Amar Vamsi Krishna

Systems Engineer

Amar has a Master of Science degree in Systems Engineering (with a focus on Robotics) from the University of Maryland at College Park. Having developed an interest in Rehabilitation Robotics through the course of his Masters’ thesis, guided by our CTO, Dr. Anindo Roy, he joined the team at NextStep. At NextStep, he works as the Systems Engineer working on the technical architecture of various aspects of AMBLE, and leading the effort on the Quality Management System.

Ezra Altabet

Mechanical Engineer

Ezra earned his Bachelor of Science in Mechanical Engineering from the University of Maryland, College Park. He conducted an undergraduate Engineering Honors Thesis under NextStep’s CTO, Dr. Anindo Roy, and developed the first ever prototype of REACH, an affordable rehabilitation robot for training reach-and-retrieval in patients suffering from upper-extremity impairments resulting from stroke. He is now the lead engineer on NextStep’s REACH project, and is working to make affordable stroke therapy a reality. In his free time, Ezra loves to read, play piano, and practice taekwondo.
