About

Mahdi Jazini portrait
MJ
Pittsburgh, PA

I build non-invasive hemodynamic monitors — hardware, signal pipelines, ML — that hold up against the catheters they're trying to replace.

I'm a PhD candidate in Bioengineering at the University of Pittsburgh (Biosignals track), advised by Prof. Ramakrishna Mukkamala in the Cardiovascular Health Tech Lab. My work spans custom hardware, signal processing, and machine learning — non-invasive sensors across the whole hemodynamic stack, validated against invasive references in multi-site surgical studies.

I came to Pitt after a Master's in Integrated Circuits from University of Tehran and a Bachelor's in Digital Electronics from Amirkabir University of Technology. Between degrees I spent three years at Tosan Co. leading 14-layer mixed-signal PCB design and microprocessor signal-processing chains — I came to research with a production mindset.

I care about the parts of medical devices most people never see: the PID loops, the noise floor, the calibration drift, the pneumatic transients, the DSP and ML pipelines that turn raw physiology into meaningful vitals. That's where patient safety lives — and where honest accuracy begins.

Research Focus

Non-Invasive
Hemodynamic Monitoring

Cardiac output, blood pressure, HRV, and respiration — pulled out of the body without a single needle. PPG at the fingertip, BP at the arm, ECG on the chest, respiration from the cuff. One patient, many modalities.

Mixed-Signal
Medical Hardware

Custom PCBs (up to 14 layers), analog front-ends for PPG / ECG / pressure / respiration, pneumatic pump & valve control with PID, bring-up and failure analysis.

Signal Processing
& ML for Physiology

PPG and ECG denoising, harmonic-SNR quality gating, R-peak detection, pulse-pressure envelope fits, respiration extraction, and ML for hemodynamic parameter estimation.

Try the research

The physics behind the cuff: arterial blood volume.

An arm cuff doesn't measure pressure directly — it reads tiny volume oscillations in the brachial artery. That volume vs. transmural pressure is sigmoidal, and the slope (compliance) peaks where mean arterial pressure lives. Drag the cuff pressure: the left panel shows the model, the right panel shows the artery cross-section, pulsating and collapsing in real time.

Cuff pressure 150 mmHg
Transmural P (mean) −57 mmHg

Same hobby, different decade

It's all just signals.

Chased a decaying sine wave off a SAW sensor in 2018. Chasing an oscillometric envelope off an arm cuff now. The physics is different — the tricks are the same. Watch one morph into the other:

FAQ

The questions I get asked most often by recruiters and collaborators — answered up front, so we can use our first call for the interesting stuff.

When are you available to start?

I will defend in late 2026 and am targeting a January – March 2027 start date. For the right role I can consider a part-time or research-collaboration engagement earlier while I wrap up.

Remote, hybrid, or on-site?

All three work. I'm based in Pittsburgh but open to relocating anywhere in the U.S. — East Coast, West Coast, or anywhere with an active medical-device R&D ecosystem. For a great team I'll also consider Europe or Canada.

What kind of team fits you best?

I do my best work in early-stage investigation groups for R&D — clinically grounded teams shipping non-invasive vitals, wearables, or hospital-grade home monitors. Small-to-mid size ideal; I'll happily own a cross-discipline lane.

Have you worked on regulated medical devices?

My clinical studies are IRB-approved and follow human-subjects research protocols. I haven't led a formal 510(k) or IDE submission, but I've worked adjacent to design controls, IEC 62304 software lifecycle, and ISO 14971 risk management — and I can speak the language from day one.

Can you code, or just design hardware?

Both — honestly, I'm an embedded systems engineer at heart, so I code and design electronics together; which side leads depends on the project. I ship the whole stack: custom PCB → firmware → signal processing → ML → clinical GUI. Python daily (Pandas/SciPy/PyTorch/PyQt), C/C++ for embedded, MATLAB for quick prototyping, Git for everything.

References?

Available on request — my PhD advisor and clinical collaborators (PIs and Co-PIs). Reach out by email and I'll share contact details.

How should I reach you?

Email is fastest: Mahdi.Jazini@pitt.edu. LinkedIn DMs work too. I reply within a day or two.
