Introduction
I am a cross-disciplinarian who has studied hardware/software engineering, digital signal processing, music, physiology, manual therapy, and somato-emotional release. Currently I am applying my passion for healing arts to my expertise in technology, to create a neurovascular flexibility training tool called Pranawave.
My research interests include the baroreflex, lymphatic system, neurovascular bioacoustics, resonant breathing, and central autonomic network regulation by intrinsic 0.1 Hz waves.

Heart rate variability (HRV) biofeedback is clinically useful for the treatment of physical and mental disorders involving dysregulation of the autonomic nervous system (ANS). HRV biofeedback involves paced breathing near six per minute (~0.1 Hz), near the primary natural frequency of the baroreflex, which results in maximal respiratory sinus arrhy...
Intrinsic neurovascular oscillations near 6 per minute have essential regulatory functions for physical and mental health. Controlled respiration near six breaths per minute amplifies this intrinsic regulation, and creates a balanced respiratory cycle that strongly flexes the autonomic system between parasympathetic and sympathetic with each breath...

A new vertical electric field antenna has been installed at our West Greenwich, RI Schumann resonance field station, coupled to a high-bandwidth charge amp and a computerized sampling system. Techniques are given for the processing of lightning transients. Digital signal processing techniques for the removal of power line harmonic noise are present...
The bandlimited digital synthesis model of Stilson and Smith is extended with a single feed-forward comb filter. Time-varying comb filter techniques are shown to produce a variety of classic analog waveform effects, including waveform morphing, pulse-width modulation, harmonization, and frequency modulation. The techniques discussed are not guarant...
This study is concerned with the electromagnetic radiation from
lightning propagating in the Earth-ionosphere cavity, whose wavelengths
range from the circumference of the Earth, to the height of the
ionosphere, to the lengths of return stroke channels. A new ball-type
antenna for the vertical electric field has been constructed in West
Greenwich,...

Hello,
I recently published a short proposal about the health promoting effects of six per minute non-invasive ventilation, founded on over 30 years of clinical research in HRV biofeedback:
Research Proposal Six per minute non-invasive ventilation: Resonant Frequency ...
I would love to hear from clinicians about this idea, and collaborate with any interested parties. Thanks!
Abstract:
Controlled respiration near six breaths per minute creates a balanced respiratory cycle that strongly flexes the autonomic system between parasympathetic and sympathetic with each breath -- baroreflex circuit resonance drives maximum respiratory sinus arrhythmia (i.e. vagal-associated HRV) which strongly oscillates vascular tone, heart rate, and blood pressure. This perfect balance of relaxation and alertness recharges the homeostatic function, optimizes neurovisceral integration, promotes efficient pulmonary gas exchange, reduces pain perception, stimulates anti-inflammatory reflexes, and enhances resilience to physical and emotional stressors. Therefore I propose the study of six per minute ventilation on COVID-19 patients, delivered non-invasively through BiPAP S/T, to promote beneficial neuromodulation against vascular and immuno-inflammatory complications.
In particular, the Barbieri point-process papers don't seem to give enough information to practically implement without some extra inside knowledge.
Previously there was a .mex file used to hide some of the details, but it was not cross-platform compatible and seemed to be windows only.
I am interested in applying these tools in biofeedback methods.
Thanks!
