My current work uses machine learning and graph analytics to locate known functions within obfuscated binary programs.
Low-level tools like compilers, programming language libraries, and hardware synthesis engines form the foundations of modern hardware and software supply chains, so their security and efficiency is especially important. High-quality foundations enable developers to build with confidence and produce more trustworthy hardware and software.
By advancing the state of the art in this niche, I hope to improve the performance and security of this critical infrastructure.

I have been teaching core courses at Indiana University’s Intelligent Systems Engineering program since 2016. My teaching style includes a lot of hands-on examples, live coding, and an environment where I hope students are comfortable to ask questions and try things themselves. Most of my classes are a mixture of lecture and lab. Because not everyone learns the same way, I employ lots of different learning methods - participation, projects, take-home style quizzes, and readings.
Engineering Computer Architectures
ENGR-E 110, Spring Session (16 weeks), Summer Session (6 weeks).
This course teaches the fundamentals of digital logic. Starting with boolean functions (And, Or, Not) and building up to a simulated CPU which can run programs, to shed light on the mystery of computation. This course is inspired by the wonderful Nand2Tetris curriculum by Nisan and Schocken at MIT.
Through this course, students are also introduced to hardware description language (HDL) concepts, assembly language, and they have ample opportunities to hone their Python skills. Learning objectives include:
- understanding two’s complement arithmetic (addition, negation, subtraction)
- understanding how pointers work in a Von Neumann architecture
- crafting an assembler for a small assembly language using Python as the implementation language
- solve problems using string processing
- understanding the fundamentals of HDLs
Software Systems Engineering
ENGR-E 111, Summer Session (6 weeks).
This course teaches students C programming and the fundamentals of how to interact with memory through a CPU. Students learn C language syntax and concepts like functions, control flow, and data storage classes. Most work is exercise-based, where the goal is for the student to write programs which pass assorted tests (some visible, some hidden).
Learning objectives include:
- write functions in C
- write programs in C that process command-line arguments
- solve problems using arrays
- understand pointer semantics, including C pointer arithmetic
- understand size and speed trade-offs when manipulating data by pointer
- use C’s
structfeature to define custom data structures
- manipulate linked list data structures
Python for Engineers
ENGR-E 399/599, Winter Session (3 weeks).
Introduction to Python concepts (functions, control flow, data types, file I/O), and selected libraries (re, numpy).
Engineering Ethics and Professionalism
ENGR-E 299, Fall Session (8 weeks).
Ethical and professional considerations of the engineering field, with emphasis on software and systems.
These are courses I taught previously, but not within the last year.
Innovation and Design
ENGR-E 101, Fall Session (16 weeks).
Introduction to the breadth of engineering offered at IU’s Intelligent Systems Engineering program. Students design their own projects to solve a specific problem, with feedback and guidance from instructors. This course serves as an introduction to programming in Python, and also gives students experience in fabrication and creating models using CAD tools.
HDL Online (website)
A basic online editor for the hardware description language called simply HDL from Nand2Tetris. The URL updates with a permalink to the code as you edit, for ease of sharing.
Simple Scene Detection (PDF)
A machine learning project.
A Convolutional Neural Network (CNN) to classify two types of image (“simple” versus “regular” scenes). The images were taken by infants wearing head-mounted cameras, and researchers wanted to know if younger infants prefer “simple” scenes. My contribution was to provide an automatic image classification system so that researchers don’t have to spend so much time labeling images by hand.
GPU Support for J (PDF)
Adding a GPU interface to an interactive/interpreted programming language.
This was a project for a class called “High Performance Computing”. It uses J’s foreign function interface (FFI) to call ArrayFire functions. With compatible hardware, this speeds up certain operations. This work was a proof-of-concept intended to find a “cross over” point where the acceleration of the GPU offsets the latency of transferring data from CPU to GPU.
Obscura (Chrome Extension)
This extension is a simple filter that makes web pages darker. The reason I made this was in response to the complexity of existing solutions.
Psych-Button (USB keyboard. source code here)
Programmable keyboard-like user response device with sub-millisecond accuracy.
A graduate student needed something with 4 “normal” buttons and a “home” button with sub-millisecond timing resolution. The “home” button is my favorite part. It is a screw conductively coupled to a capacitive-sensing pin on a Teensy LC, with a library to make it behave like a pushbutton switch.
The Skinny (embedded system)
Measures and records skin conductance levels.
Myself and another engineer built 30 of these for an honors-level Psychology course at Indiana University. The device records skin conductance between 2 electrodes and logs the data to a micro SD card. Students devised their own experiments around the device, and presented their results at the end of the course. Experiment topics ranged from “watch a scary movie” to “listen to your favorite music”.
