Expertise

Multimodal data processing

My PhD thesis work has heavily involved the design and implementation of non-human primate experiments that involve recording many streams of data simultaneously. These include:

  • Neural population spiking activity

  • Hand position

  • Gaze position and pupillometry

  • Gated pulse oximetry for heart rate

  • Surface electromyography (EMG)

Each data stream has different quirks and challenges for processing, but combined, provide valuable insights into the cognitive processes underlying behavior.

Data analysis

My research mainly focuses on neural population analyses - Using statistical and machine learning methods, I leverage hundreds of simultaneously recorded neurons in the motor cortex of the brain to identify behaviorally-relevant patterns of neural activity. These methods often rely on dimensionality reduction to identify low-D patterns in high-D neural activity.

 

More generally, I'm experienced with answering quantitative scientific questions with data analysis and statistical methods.

Engineering

...but to even get any of this data, a fair bit of engineering is involved! Simple electrical engineering skills were useful for building basic circuits for signal acquisition (e.g., hand tracking markers, pulse-ox) and hardware/software filtering the signals they output.

 

I also wrote the software program to run the task shown in the video above from scratch to maximize my ease of use and customizability.
