In modern healthcare, a critical gap often persists between theoretical physiology research conducted in academic laboratories and the practical diagnostic tools available at the patient’s bedside. Bridging that divide requires a rare combination of clinical expertise, scientific rigour, and entrepreneurial vision.
Dr. Maruthy K N, a veteran medical educator, researcher, and MedTech innovator, has spent over two decades doing precisely that—transforming complex physiological principles into life-saving, point-of-care medical technologies.
The Making of an Academic Leader
Dr. Maruthy’s foundation in medical science began with a D.Bact from Bangalore University in 1993, followed by an MD in Physiology from Rajiv Gandhi University of Health Sciences (RGUHS) in 1999. Over a career spanning more than 25 years, he has built an exemplary reputation in medical education, serving in key academic leadership roles across several of India’s premier medical institutions:
PES University / PES Institute of Medical Sciences: Professor, Department of Physiology
MVJ Medical College & Research Hospital: Professor & Head of Department (HOD) of Physiology
Narayana Medical College, Nellore: Professor & Head of Department (HOD) of Physiology
St. John’s Medical College, Bengaluru: Associate Professor of Physiology
Throughout his academic tenure, Dr. Maruthy has mentored generations of medical students and postgraduate researchers. Beyond traditional lecturing, he has been a strong advocate for pedagogical evolution, integrating e-learning frameworks (such as Bloom’s Taxonomy and Miller’s Pyramid), outcome-based education, and interdisciplinary problem-solving into standard medical training.
Translating Autonomic Physiology into HealthTech Solutions
Dr. Maruthy’s career stands out for its translational focus. Rather than keeping physiological research confined to academic publications, he co-founded Yostra Labs in 2014 alongside an interdisciplinary team of clinicians, designers, and engineers, serving as its Scientific Advisor and Chief Scientist.
At Yostra, Dr. Maruthy applied his deep understanding of the Autonomic Nervous System (ANS) and peripheral vascular dynamics to address critical complications associated with chronic conditions like Type 2 Diabetes:
1. Early Screening for Diabetic Neuropathy
His physiological expertise guided the development of NEURO TOUCH, a portable, 5-in-1 multi-parameter point-of-care screening device. By evaluating both small and large nerve fiber responses (vibration perception, thermal sensation, and tactile sensation), the device enables early detection of peripheral neuropathy before irreversible tissue damage occurs.
2. Advanced Wound Care & Vascular Health
By analyzing peripheral microcirculation and tissue oxygenation, his research contributed to therapeutic innovations such as VELOX CARE / KADAM™ (warm oxygen therapy), designed to accelerate the healing of chronic diabetic foot ulcers and reduce amputation rates.
“By converting complex cardiovascular and nervous system parameters into accessible digital diagnostic metrics, healthcare providers at primary care centers can screen for diabetic microvascular complications early—saving lives and limbs.”
Deep Analysis: Scientific Contributions & Research Focus
With over 80 peer-reviewed research publications, Dr. Maruthy’s academic output focuses heavily on cardiovascular physiology, clinical neurophysiology, and non-invasive diagnostic methodologies. His key investigative thrusts include:
Heart Rate Variability (HRV) & Autonomic Balance: Investigating how subtle shifts in HRV serve as early warning indicators for diabetic cardiac autonomic neuropathy and cardiovascular risk.
Arterial Stiffness & Vascular Aging: Assessing central arterial compliance using non-invasive pulse wave analysis and photoplethysmography (PPG).
Dynamic Pupillometry: Developing diagnostic apparatus to quantify the pupil light reflex as a non-invasive window into autonomic nerve functioning and neurological health.
