Actively working with the Össur Power Knee as a postdoctoral researcher at the University of Michigan. I am mentoring a student on adapting the lab's data-informed biomimetic controller to commercial hardware for incline and decline walking. My involvement is experimental testing and discussing controller changes for accommodating the device's passive ankle. Video of related work

Mentored several students as a postdoctoral researcher and contributed to their research in phase-based impedance controllers for powered prostheses, including experimental evaluation with recruited transfemoral amputee participants. I also led the design and execution of an endurance study evaluating classifier performance and biomechanical outcomes.

A GUI made in PySide6 for real-time monitoring and controlling of a powered prosthesis, showing live sensor data and sending user control inputs using custom Qt widgets. The backend is a shared variable framework using ZeroMQ for bidirectional data communication across multiple devices, allowing flexibility and ease-of-use for future users. Developed with agentic tools under my direction.

A tool for navigating and modifying deeply nested data structures in MATLAB using concise string expressions, similar to XPath. It replaces repetitive loops and temporary variables when working with hierarchical data, reducing the amount of code dedicated to data-wrangling. The open-source code is on Codeberg and is developed with agent-assisted coding under close manual review and direction.

An experimental English keyboard layout that dedicates keys for frequent letter sequences such as the, ing, and er to reduce total typing effort. I am taking a data-driven approach to both select the macro keys and using combinatorial optimization for the placement of the keys. The open-source code is on Codeberg and was built with agentic coding.

Regularly contribute to OpenStreetMap, an open-access geospatial database supporting GIS tools and enabling independent alternatives to proprietary map apps/services. I have made over 100,000 contributions across 1,500+ edits in the US, primarily in Ann Arbor, MI through ground surveys and Elyria, OH using aerial imagery. My user profile shows my contribution history.

Provides a MATLAB tool that organizes multiple arbitrarily dimensioned variables in a struct-like object wherein semantically related dimensions are linked across variables. This allows for multi-variable simultaneous slicing or indexing, reducing repetitive indexing especially otherwise common in for loops. The open-source code is on Codeberg and was developed without agentic tools.

Developed and experimentally evaluated novel control strategies on the Indego Explorer exoskeleton, formerly developed by Parker Hannifin and now Ekso Bionics. As a postdoctoral researcher at Cleveland State University, I designed a hybrid impedance-sliding mode controller and a hybrid zero dynamics controller with optimal phase definition. Video

I designed and prototyped an anthropometrics-based 3D-printed exoskeleton using a methodology intended to adapt for growing children with cerebral palsy. The custom-developed actuator was characterized and experimentally tested using provisional hardware and an adult prototype for feasibility. This work was in collaboration with Parker Hannifin.

As part of a 7-person undergraduate capstone team, we developed and fabricated a hydraulic drive system for an adult tricycle. My focus was performance analysis of the system prior to fabrication, with additional involvement in design, manufacturing, and testing. Our team entered into the Parker Hannifin Chainless Challenge, a competition of universities across the US. Video

Developed a machine-to-machine networking protocol and API as part of an international team. The system featured a hybrid tree and peer-to-peer topology with general message routing protocol and resilient topology state propagation. A remote-control example was demonstrated using LEGO Mindstorms EV3 robots at the 2014 City Campus exhibition in Trier, Germany. Video
