I'm a 2nd year Computer Science PhD student at the University of Arizona specializing in NLP/DL and its intersections with Cognitive Science. My main research interests lie towards enhancing compositional reasoning (and compositional generalization) capabilities within large language models (LLMs). I am currently working on methods that probe "outside the blackbox" i.e. expose models to "good" data and the "right kind" of data, that makes compositional knowledge explicit.I am also interested in "small" language models, especially neuro-symbolic and modular architectures, that are efficient, usable in "Zero Ground Truth" settings and easily adaptable to specialized domains.As evidenced by my experience with both academic research and industry internships, I'm eager to drive innovation and contribute to the frontiers of AI, LLMs and the programmatic creation of high quality datasets under settings of extremely light supervision/zero ground truth.

Data Science InternKaiser Permanente Jun 2023 - Aug 2023San Francisco, California, United States- Focused on the development of efficient NLP models for identifying social health indicators from clinical text, aiding in comprehensive patient health assessments.- Built a diverse labeled training dataset of 1 million+ provider notes using heuristic annotations, zero-shot learning with LLMs, human-in-the-loop active learning and multiple weak supervision strategies.- Used this dataset to train an NLP model that achieved over a 90% F1 score in expert evaluations, a state of the art in pinpointing key social determinants of health.- Deployed this model into production where it is currently capable of batch inference on millions of provider notes every month.- Gained hands-on experience with Hive, AzureML, Snorkel Flow/Snorkel AI, John Snow Labs’ NLP and Docker deployment. -

Undergraduate Research AssistantTukl-Nust R&D Center Mar 2020 - Jun 2021Nust-SeecsWorked on my bachelor's thesis: "Handwritten Sequence Recognition with Time Series Transformers".Implemented a Time Series Transformer (TST) - a variant of the vanilla transformer architecture for handling multivariate time series data with modifications to the input embedding and positional encoding layers.Curated a dataset of sequences of IMU sensory data collected from a Myo-armband representing user arm movements corresponding to text-written In-Air. Trained an encoder-only transformer to achieve close to SOTA accuracy on In-Air handwritten character/digit level classification tasks.Experimented with an encoder-decoder version of the Time Series Transformer to reconstruct the full handwritten sequence from IMU sensory data.

Machine Learning InternCern Aug 2020 - Dec 2020Geneva, Switzerland- Trained 3D U-Net regression models to predict fluctuations in space charge distortions inside a type of particle detector known as the Time Projection Chamber (TPC).- Developed a validation strategy for comparing different UNet model configurations in Tensorboard.- Enhanced the accuracy of the standard UNet model by incorporating parallel dilated convolutions andresidual connections, resulting in superior performance, particularly in terms of RMSE, during training oncoarse-grained input maps. -
Summer StudentCern Jun 2019 - Aug 2019Geneva, Switzerland- Internship with AliceO2 group supervised by Gian Michele Innocenti.- Worked on the binary classification of rare signal versus background in ultra-relativistic heavy-ion collisions, as part of an open source library used by the ALICE experiment.- Implemented and compared performances of XGBoost, Random Forest & Keras algorithms on large imbalanced datasets.- Implemented Bayesian search to speed up hyperparameter tuning of ML models by 5X, compared to grid search.
