I am a tech researcher, academician, writer, and podcast host. I contribute to cross-disciplinary areas of electronics, photonics, and computer science. My current interests are graphical password security and STEM education. My expertise includes, but is not limited to, theory and practice of optical and digital information processing, holography and 3D imaging, image processing, pattern recognition, and optoelectronic information systems development. ► WHAT I DO: I design and develop solutions for Privacy-Protected Digital Identity, Password and Cybersecurity, and Distributed Ledgers. I also mentor college students in advanced courses and projects in Electronics, Computer Engineering, and IT through 3D Education, placing them in industry internships and helping them kickstart their careers. ► RESEARCH: My current research focuses on authentication technology, especially graphical passwords and privacy-protected digital identity systems using distributed ledger technologies. I conducted extensive research on 3D facial recognition and multimodal facial and fingerprint biometrics, applying it to asymmetric cryptosystems. I founded a new direction in artificial color perception using microwave technology. I developed a He-Ne laser-based precision displacement measurement system for monitoring moving machine parts. ► BUSINESS: I have co-founded several IT startups, including Infosensys Research, DAZ Labs Asia, IoTektronix, and educational startup Learning Times, to augment STEM education and associated career opportunities. I am the Co-Founder of the LinkedIn Group "The Unfluencers." ► MEDIA FEATURES: (i) Tech Podcast "Identity Crisis: The Future of Password Security Systems" by Neil Hughes in Dec 2018. (Ii) Forbes Magazine Entrepreneurs channel by Cheryl Snapp Conner in 2015 and 2016. ► HONORS:: (i) Guest of Honor at the 70th Independence Day Celebration, AVB IIITM, Gwalior (15 August 2016, Gwalior), INVITED TALKS: (ii) "Tribute to H. John Caulfield" (SPIE, 2013, San Diego, CA), (iii) "3D Imaging, Metrology, and Data Security" (Shenzhen University, 2015, China). ► CONTACT: I am available to consult online or offline.
