My Expertise

Biomechanics

Quantifying the 3D motion and dynamics of rigid bodies through physics-based algorithms

Rapid Prototyping

Fast and inexpensive fabrication of solutions via 3D CAD, 3D printing/cnc milling, and progamming microcontrollers.

Data Processing/Visualization

Translation of biomedical signals into understandable 3D graphical representations

My Resume

Expertise

Biomechanics

Extensive experience quantify human motion with the use of motion capture, instrumented forceplates, EMG, wearables, computation MR imaging, and computer modeling using high-speed dual fluoroscopy.

Data Analysis/Visualization

Developed software in C and MATLAB responsible for the estimation of joint kinematics, joint dynamics, contact locations, and cartilage thickness maps using 3D subject specific surface models of human tissues. Implentation of pointcloud estimations, image processing, and 3D rigid body transformations.

Rapid Prototyping

Considerable experience in taking an idea and bringing it to life. Namely the execution of designing (CAD), Manufacturing (additive and subtractive), and Programming microcontrollers

Leadership

Managed the Muskuloskelatal Imaging and Orthopedic Biomechanics lab including the mentoring of an army of undergraduate and graduate students.
Former collegiate varsity football player.
Most importantly... was a supervisor at a brewery and former supervisor of a RoastBeef Deli.
