The effects of distraction on brain processes underlying signal detection
Published in Neuropsychologia, 2016
This work leverages the high temporal resolution of EEG to study the neural consequences of a global, continuous distractor on signal-detection processes.

Deep Generative Analysis for Task-Based Functional MRI Experiments
Published in Journal of Machine Learning Research, 2021
In this work we follow a Generalized Additive Model (GAM) approach to construct a 3D convolutional VAE capable of more flexibly modeling entire brain volumes, while preserving interpretability.

Inflationary Flows: Calibrated Bayesian Inference with Diffusion-Based Models
Published in ArXiv (preprint), 2024
In this project we exploited a previously established connection between the stochastic and probability flow ordinary differential equations (pfODEs) underlying Diffusion-Based Models (DBMs) to derive a new class of models, inflationary flows, that uniquely and deterministically map high-dimensional data to a lower-dimensional Gaussian distribution via ODE integration.

I was a teaching assistant for the graduate cardiac physiology course at University of Brasilia’s School of Medicine (Brazil).
Physics 141L & 142L
Undergraduate course, Duke University, Physics, 2015
I was a teaching assistant for Physics 141L (Classical Mechanics) and 142L (E&M) for life science undergraduate students at Duke during the summer of 2015. These courses were taught during Summer Sessions I, II and were conducted at Duke’s marine laboratory campus in Beaufort, NC.
ECE682D
Graduate course, Duke University, Electrical and Computer Engineering (ECE), 2023
This is a graduate course on probabilistic machine learning methods cross-listed between ECE, Statistics, and Computer Science (CS). It covers key concepts in prediction and decision making typically encountered in machine learning and data science, under a more formal statistical viewpoint. For additional details, see course website here. For my work as a TA for this course, I was selected to receive Duke ECE’s outstanding graduate student TA award on Spring 2023!
ECE586
Graduate course, Duke University, Electrical and Computer Engineering (ECE), 2023
This is a graduate course introducing incoming ECE masters and PhD students to fundamental concepts in logic and set theory, metric spaces, topology, vector spaces, and convex optimization. For additional details see course website here. For my work as a TA for this course, I was selected to receive Duke ECE’s outstanding graduate student TA award on Spring 2024!
