Mutable Hardware: IoT devices, bioimplantables, and other highly constrained embedded systems often lack the device resources to perform complex cryptographic routines, have too stringent size or weight requirements to support the necessary hardware, or support all the above, yet are still vulnerable to advanced hardware-level attacks. As society becomes increasingly reliant on such digital systems, security is more important than ever for personal, corporate, and national security. I focus on developing practical, lightweight, and robust security solutions for such devices, especially considering a system-level security perspective. MUTARCH is a hardware design flow inspired by nature, which creates unique and time-mutable evolving hardware from a single base design.

Domain-Specific Spatiotemporal Computing: Reconfigurable fabrics like FPGAs or FPGA-like devices bridge the gap between costly yet efficient ASICs, and inexpensive general-purpose processors which have comparably poor performance. Still, they suffer from low scalability and energy-efficiency, limiting their utility. Domain-specific spatio-temporal architectures can provide comparable performance at lower power consumption, trading off some flexibility for improvements in efficiency, while still retaining the ease of programming

Bladder Pressure Event Detection: Lower urinary tract dysfunctions, such as urinary incontinence and overactive bladder, are conditions which greatly affect the quality of life for millions of individuals worldwide, including those with certain Spinal Cord Injuries (SCI). Recent work in implantable sensors has led to the WIMM, a wireless, implantable micromanometer for chronic bladder pressure measurement. Analyzing single-sensor bladder pressure is extremely challenging in humans due to significant noise and dampening due to other physiological structures. Context Aware Thresholding (CAT) was designed to analyze such pressure recordings and differentiate between bladder events – useful for advanced treatments such as neuromodulation.
