Engineering the Electromagnetic Interface to Life.

I develop electromagnetic and computational interfaces that sense, communicate with, and ultimately control living systems, from proteins and cells to neural tissue and future wireless networks. My research vision is summed up in TAYF.

TAYF (طيف) — Arabic for spectrum

Protein, cell, tissue, and neuron research scales connected to a wireless communication tower.

TAYF brings these ideas into a common framework, using electromagnetic waves not only as carriers of information, but as engineered interfaces between physical and living systems. Across scales, the goal is to uncover how fields can probe biological dynamics, convey information, and ultimately enable precise interaction with living matter.

about

I am a postdoctoral fellow in the Ultrabroadband Nanonetworking Laboratory at the Institute for Intelligent Networked Systems at Northeastern University, working with Josep Jornet as my advisor.

My path took me from Abu Dhabi to Toronto to Boston.

Postdoctoral Fellow · Present

My fascination with the nanoscale began during my senior undergraduate year as I developed a deeper understanding of communication systems. During my Ph.D., one question kept returning:

Can electromagnetic waves communicate with biology — not just carry information between devices, but directly interact with proteins and living systems?

Exploring that question led me into the world of bioelectromagnetics. What began as an investigation of terahertz interactions with individual proteins gradually evolved into a broader pursuit spanning sensing, actuation, communication, and intelligence across biological and engineered systems.

TAYF is the culmination of that journey — a research vision dedicated to engineering an electromagnetic interface to life.

Current Research Projects

THz Intra-body Communication, Sensing, and Actuation

terahertz intra-body sensing & actuation
Question
How can nanoscale wireless systems communicate, sense, and actuate reliably inside biological tissue?
Approach
Physical-layer and propagation modeling for wireless nanonetworks operating inside biological tissue: THz channel characterization, wave–tissue interaction modeling, signal processing, and information-theoretic analysis of intra-body links.
Impact
Establishes the engineering foundations for implantable nanoscale wireless devices capable of real-time sensing and actuation at the molecular level, with applications in continuous health telemetry, closed-loop therapeutics, and future 6G body-area networks.

Near-field Wavefront Engineering: Communication and Sensing

near-field structured beams ISAC
Question
Can structured near-field wavefronts create new degrees of freedom for communication and sensing?
Approach
Exploits near-field electromagnetic effects to unlock spatial degrees of freedom beyond far-field limits, enabling high-capacity THz links and super-resolved sensing.
Impact
Advances a system-level near-field THz framework applicable to dense wireless infrastructure (AI factories, intra-datacenter links) and sub-millimetre sensing, directly enabling the distributed ISAC architectures targeted by NSF and DEVCOM programmes.

EM Wave Propagation in Hydrogel-based Neural Tissue Scaffolds

hydrogel neural tissue structured illumination
Question
How do optical fields and scaffold mechanics jointly shape the interface experienced by growing neural tissue?
Approach
Investigates electromagnetic wave propagation through riboflavin-crosslinked hydrogel media as a system-level design problem, characterizing how structured illumination shapes the resulting scaffold properties.
Impact
Establishes structured illumination as an engineering-controlled propagation variable, enabling reproducible scaffolds for neural tissue modeling and new routes for EM-based characterization of engineered biological media.

Bacterial Intelligence and Biofilm-based Biocomputing

biofilm biocomputing 6G mMTC
Question
Can living microbial communities become both sensing media and computational substrates?
Approach
Characterizes EM wave propagation through biofilms and harnesses bacterial collective signal-processing for biocomputing and non-invasive infection sensing, integrating gene regulatory neural network models with 6G mMTC system design.
Impact
Expands molecular communication theory to living computational substrates, with relevance to biocomputing architectures, EM-based detection of antimicrobial-resistant biofilms, and bio-inspired intelligence for 6G network control.
