 The following presents my research interests. Because I have developed a very broad spectrum of knowledge in multiple disciplines, my personal approach to any investigation culminates at achieving understanding governed by interrelatedness of all components involved from holistic perspective. 

Primary Interests: 

1. Phylogenetic systematics applied to non-biological systems: In natural tropospheric lightning, dominance exhibited by intracloud discharges over any thunderstorm lifetime, necessitates a question on why lightning contacts ground at all; which, in addition, is being an energetically unfavorable process. Transient in their duration with populations accounting for thousands, lightning discharges appear to be “evolving” governed by changing conditions of the convective system, and ultimately manifest as a hierarchy of specific types of discharges. The goal of this research direction is to reveal the reason for diversification and interrelatedness of natural lightning discharges by employing cladistics and computational phylogenetic tools. 

2. Cyber-physical systems for biological and non-biological systems: Enabling next-generation cyber-physical systems requires realization of the dynamic data-facilitated high-confidence autonomous circuitry that relies on real-time sensing and learning. This direction investigates the fundamental principles 

of electromagnetic resonance SansEC (without electrical connections) sensing in application to physical and biological systems subjected to external stimuli. This cybernetic interface is based on the novel NASA technology. My recent research on flexible morphing structures has already established a capability of SansEC sensing to predict system’s response to mechanical excitation through the machine learning technique. My plan is to continue further exploration of SansEC sensor applications to biological systems to enable measurements of psychological and physiological biomarker profiles through the non-invasive subcutaneous penetration of electromagnetic field, generated by SansEC sensor. 

Derived Interests: 

1. Carbon-based nanophotonics: Low-dimensional carbon-based nanostructures offer diverse optical properties; but on-demand scaled-up designs are inhibited by the lack of knowledge in predicting nonlinear responses. My recent investigations revealed an unexpected fluorescence in electrospun polyacrylonitrile nanofibers. This research direction is concerned with effects of synthesis on structure-optical property relationships. Because photoluminescence of nanosized carbon allotropes depends on crystal structure, size, morphology, and chemical functionalization—benchmarking nanostructural intermediates against these parameters can elucidate changes occurring within the electronic structure of the material. 

2. Lightning-proxy tropospheric spectroscopy: Ecological health of tropospheric chemistry plays a critical role in radiative climate balancing. Ability to detect and interpret lightning discharges can deliver a unique tool that identifies effects of air chemistry and atmospheric thermodynamics on natural plasma formation in thunderstorms. Superior sensitivity and 

space-time variability of lightning enables lightning to serve as a natural spectroscopic probe, operating in situ, for monitoring weather convection and precipitation. This innovation holds potential for extending this technology onto the planetary scale by creating a space-based optical-electromagnetic lightning detection sensor system integrated into a CubeSats constellation orbiting the Earth.
