I'm a fourth-year PhD student at Carnegie Mellon in a joint program between Machine Learning and Neural Computation. I am most interested in investigating the flow of information in the human brain during language processing. To get closer to this goal, I work with my advisor - Tom Mitchell - on combining machine learning approaches, ranging from decoding to causal inference and discovery, and applying them to high-dimensional time series Magnetoencephalography data. My research is supported by the NSF graduate fellowship. Before beginning my graduate studies at CMU, I received a B.S. in both Computer Science and Cognitive Science at Yale University.

I also enjoy taking care of (helpful) bacteria and turning them into yogurt and sourdough bread from time to time.

During Fall 2016, I served as a Teaching Assistant for the course Convex Optimization taught by Ryan Tibshirani and Javier Peña, and was recognized with the ML TA award.

During the summer of 2016, I was fortunate to teach a lecture series on machine learning for neuroscientific applications as a part of the 2016 Multimodal Neuroimaging Training Program. MNTP is a summer program aimed at graduate students trained in neuroscience who would like to gain more experience in a different neuroscientific modality.

My goal in putting together the curriculum for this machine learning module was to give an intuitive overview of machine learning concepts that are useful for working with neuroscience data.

Lecture 1: classification (naive Bayes, SVM, kNN) & regression (linear) [audio did not work, so no video for this one] [slides]

Lecture 2: model selection (overfitting, cross validation, feature selection, regularization) & significance testing (permutation test, multiple comparison corrections) [slides]

Lecture 3: dimensionality reduction (PCA, ICA, CCA, Laplacian eigenmaps) & clustering (k-means, spectral clustering, divisive clustering, agglomerative clustering) [slides]

Lecture 4: latent variable models (HMM), reinforcement learning, deep learning (RNN, LSTM, DBN, CNN), AlphaGo algorithm details [slides]
