Kevin Hannay
Chief Technology Officer
Arcascope, Inc



Currently, I am the Chief Technology Officer at Arcascope. Arcascope provides algorithmic solutions for tracking, predicting and correcting human circadian rhythms. Our technology allows for personalized predictions to be formulated efficiently and accurately using commericial wearable devices. Feel free to contact me if you are interested in joining our team at Arcascope or if you would like to partner with us.

Software Development

I have been programming for over 15 years and really enjoy developing software. The most common langauges I use for programming are Python, Swift, R, Julia and C/C++.
  • Check out my github page for software I have developed.
  • A package which implements both my and some other circadian models is available on PyPI.
  • For my Schreiner University statistics class I have also written an RPackage which can be installed in R using the command:



I also have a side interest in hacking, penetration testing, reverse engineering and malware analysis. This has been a growing passion of mine for the last few years. You may see me competing in CTF competitions.
