Seeing the Invisible: The Future of Infrared Detection

Utkarsh Singh on Poisson Bolometers and Nanoscale Infrared Detection at Purdue ECE Host Kristin Malavenda interviews Purdue ECE PhD student Utkarsh Singh about his path from New Delhi to Purdue and his research on nanoscale spintronic devices for long-wave infrared (8–14 µm) detection. Singh explains how nanoscale structures exhibit new physics and can enable smaller, lower-power detectors with different, more digital readout behavior than traditional analog infrared sensors. He describes Poisson bolometers, which treat fluctuations between discrete resistance states as a useful noise signal, measuring changes in switching statistics under infrared radiation rather than minimizing noise. The conversation covers applications including surveillance, biomedical imaging, astronomy, and heat-assisted detection and ranging, as well as challenges in fabrication yield, device fragility, and degradation. Singh also discusses PhD realities, advisor support, a rewarding hardware-readout success, and advice on patience, research experience, self-care, and hobbies like music, working out, and traveling. 00:00 Welcome and Guest Intro 00:50 Early Interest in Engineering 02:06 Choosing ECE Path 02:47 Why Purdue for PhD 03:49 Research Evolves Over Time 05:15 Nanoscale Devices Explained 06:20 Infrared Detection Basics 07:43 Why Nanoscale Matters 08:44 Poisson Bolometer Concept 11:23 Why Better IR Detection 13:04 Infrared Detector Roadmap 13:43 Nanofab Scale Challenges 15:08 Handling and Device Degradation 16:36 Learning From Failure 17:49 PhD Workday Rhythm 18:41 Research Direction Realities 19:48 Advisor Support Style 21:03 Breakthrough Moments 23:10 PhD Advice and Balance 24:30 Hobbies and Wrap Up Purdue ECE: http://engineering.purdue.edu/ECE Facebook: http://facebook.com/purdueece X: https://x.com/PurdueECE Instagram: https://instagram.com/purdue.ece LinkedIn: https://www.linkedin.com/company/purdue-ece The Elmore Family School of Electrical and Computer Engineering at Purdue University is one of the nation's largest and most highly ranked ECE programs.

How to Stop Software Disasters Before They Start

How to Stop Software Disasters Before They Start: Purdue PhD Paschal Amusuo on Formal Verification, Unit Proofing & Zero Trust In this episode of Engineering Innovations from Purdue ECE, host Kristin Malavenda interviews fifth-year PhD candidate Paschal Amusuo, a Qualcomm Innovation Fellow researching software security with formal verification and runtime defenses. Amusuo shares his path from Port Harcourt, Nigeria, to Purdue and explains how memory-safety bugs—like those behind major outages such as the 2024 CrowdStrike incident—can crash systems or enable attackers to steal or alter data. He describes how formal verification differs from testing by mathematically checking whether any input can cause failure, and how his “unit proofing” approach makes these techniques more accessible to software engineers. He also discusses zero-trust design for third-party software dependencies, daily PhD life, mentorship with advisor James Davis, real-world vulnerability disclosures, and advice for prospective PhD students focused on learning and impact.

Engineering Innovations: The Internet, but Make it Quantum

Engineering Innovations: The Internet, but Make it Quantum Host Kristin Malavenda interviews Purdue ECE associate professor Joseph Luken about engineering “spooky action at a distance” into real technology, including quantum communication networks and the future quantum internet. Luken explains how the quantum internet would transmit qubits and distribute entanglement, why networking is essential for scaling quantum computing and sensing, and why Einstein objected to entanglement until Bell’s later experimental tests supported quantum predictions. He describes quantum key distribution (QKD), how it detects eavesdropping, and how it contrasts with post-quantum cryptography, arguing for pursuing both given the risk of future quantum attacks. Luken discusses recent industry momentum, predicts fault-tolerant quantum computing may arrive within 10 years, and emphasizes integrated photonics as critical to moving quantum systems off optics tables and reducing loss.
