About

I am a mixed methods researcher with 7+ years of experience researching human behavior and psychology. I am currently a PhD Student at UPenn in the Computational Cognitive Neuroscience Lab . I have also conducted user research in the gaming industry at Riot Games where I researched complex patterns in user behavior that drove the design of new features.

Memory errors in behavior, brains, and machines
Our memories are not perfect recordings of the past. But instead are prone to error, misinformation, and bias. As part of my PhD, I have been identifying what memories are most susceptible to such errors. By combining behavioral experiments, fMRI, and neural networks, we show that similar memory errors exist in both humans and machines. We also find that these biases are not random mistakes, but are a product of an optimal learning system.

Impacts of indoor air quality on cognitive performance
From school to work, we spend a lot of time indoors. In this wide-scale collaboration between psychologists, engineers, and chemists, we are researching how everyday fluctuations in indoor air quality impacts cognition. We find that CO2, as well as common household fragrance products, negatively impact decision-making. This work provides actionable insights into why good building ventilation is so important.

When is the best time to learn?
Not a morning person? Most people below the age of 30 would say so. But, in this collaboration with Harvard Medical School, we tested whether or not college students do in fact learn and process information worse in the morning. Remarkably, we find that the morning is actually the best time to learn new information, especially when we have to go beyond what we learned, and transfer it to new scenarios.

Patterns across video game players in character preferences
As a personal project, I extracted player data from a public API of a popular video game to explore player preferences in what kinds of characters they like to play. Analysis code and visualizations can be found here.
