About

Mahdi Jazini portrait
MJ
Pittsburgh, PA

I build real-world sensor systems end to end — from analog front ends and embedded acquisition to signal processing, machine learning, and validation.

I'm a PhD candidate in Bioengineering at the University of Pittsburgh (Biosignals track), advised by Prof. Ramakrishna Mukkamala. Cardiovascular monitoring is my proving ground: custom hardware and algorithms 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.

That combination makes me useful beyond one application area. I work best on products where sensors are noisy, hardware and software interact, calibration matters, and the team needs evidence — not just a convincing demo.

  • medRxiv revision — addressing reviewer comments on the cardiac-output paper, then submitting to a journal.
  • Sub-diastolic hold prototype — closed-loop pressure tracking under DBP, with PDA + recalibration. Safety layers come first.
  • Real-time quality scorer — a single number per measurement, derived from harmonic SNR, motion, and arrhythmia detection. So we never silently report a bad reading.
  • Toolbox — adding a Bland–Altman builder and a PPG quality scorer. Public, free, opinionated.

The physics behind the cuff: arterial blood volume.

An arm cuff doesn't measure pressure directly — it reads volume oscillations from the artery underneath, mapped through a sigmoidal volume–transmural-pressure curve. Drag the cuff pressure: invasive arterial pressure rolls in along the X-axis, gets mapped through the curve, and rolls out as volume on the Y-axis. The output is loudest when the cuff sits exactly at MAP.

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. For a strong team and problem fit, I'll also consider opportunities in Canada or Europe.

What kind of team fits you best?

I do my best work on cross-disciplinary R&D teams building real-world sensing products. The industry can vary; the common thread is hardware, embedded acquisition, algorithms, and rigorous validation working as one system.

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.

Let's talk

Hiring for hardware/embedded R&D, sensor systems, DSP/ML, or test and validation?

I'm open to roles across medical devices, wearables, instrumentation, industrial sensing, robotics/automation, and other data-rich hardware products. Based in Pittsburgh, PA — open to relocation, hybrid, or remote.
