My name is Jeff Geisperger, a Senior Security Engineer currently focusing on the area of connected devices (IoT) and their services. I occasionally dabble in Virtualization and GPUs as well.

Currently my hobbies include building and programming embedded devices (Arduino, Raspberry Pi, Teensy, etc...), messing around with 3D Printing, Photography, travel, running and participating in Security CTFs, as well as developing applications for mobile platforms. In my spare time, I like to break things, especially software! I am also a semi-active member of the Amateur "Ham" Radio community, and can be found mostly on 2m and 15m.

I currently hold a Bachelor of Science in Computer Engineering from Northeastern University, where my Capstone project was Board Games over IP, and I did independent research on enhancing QEMU on Arm to better support x86 and have a complete working version of Windows on it.
