I'm a PhD researcher interested in explainable NLP/ML for social good ( healthcare/public policy/general knowledge )
and have had my research published in ACL, ICML, IJCAI, CoNLL, ECML amongst other venues.
Expected Graduation Summer 2022 and actively looking for job opportunities in NLP/ML research starting in Fall 2022
I'm currently a 5th year PhD candidate in Electrical & Computer Engineering (ECE) at UT Austin
working with Dr. Joydeep Ghosh's IDEAL lab and Dr. Paydayfar's group at Dell Medical School.
My research interests broadly involve explaining Machine Learning model decisions on Natural Language and sequential data, and learning representations of entities and political networks for downstream tasks. My PhD proposal accepted in June 2021 by professors Joydeep Ghosh, Alex Dimakis, Harris Vikalo, Atlas Wang & Byron Wallace is titled "In-process Diagnostic methods for Entity Representation Learning on Sequential data at Scale" and focuses on methods that allow neural networks to be more transparent, explainable, and diagnosable during the process of learning and inference as opposed to in a post-hoc analysis fashion. My research has dealt with learning sparse interpretable biomedical text representations (ACL 21), dense entity retrieval using dual encoders (CoNLL 19), prototypical learning of time series data (ICML 19(short) IJCAI 19 (long)), amongst other things. I'm currently looking at knowledge injection for the Knowledge Aware Visual Question Answering task where external world knowledge about entities is required for obtaining a correct response.
key words: interpretable entity representations, knowledge injection for multimodal VQA, dense retrieval, in-network prototype learning, dual encoders, feature importance methods, counterfactual explanations
March 2022, I was accepted as a Fulbright Specialist to work with the Center of Human Rights at UNICEN in Azul, Argentina on predicting gender bias in judicial proceedings using NLP. In addition to the researchers at UNICEN, I will be working with Dr. Maria De-Arteaga. As part of the project, we setup a workshop on AI and Public Policy/Law in Spanish.
Feb 2022, "Improving and Diagnosing Knowledge-Based Visual Question Answering via Entity Enhanced Knowledge Injection" has been accepted at ACM WWW 2022 in the Workshop on Multimodal Understanding for the Web and Social Media. Here are the slides for an invited talk on our work.
Dec 2021, preprint on "Improving and Diagnosing Knowledge-Based Visual Question Answering via Entity Enhanced Knowledge Injection" is available. Paper || Code
Summer 2021, my PhD Proposal on "In-process Diagnostic methods for Entity Representation Learning on Sequential Data" has been accepted for candidacy.
Our paper "Biomedical Interpretable Entity Representations" has been accepted at ACL-ICJNLP 2021. Paper || Code || Slides
For the Summer 2020, I have been selected to be an IBM Research PhD fellow for Social Good and will work on a Drug Repurposing for Cancer project using NLP.
I recently gave a high level talk to Cognitive Scale on Explainable AI for NLP (slides link).
In Summer 2019, I interned at Google Cloud AI in Seattle with Besim Avci and Frederick Liu working on explaining seq2seq models using feature attribution methods on Transformer and LSTM based architectures with attention for machine translation.
In Spring 2019: I was a TA for Responsible AI Graduate Seminar ( lots of papers and presentations on Explainability, Fairness, etc!)
In Summer 2018, I interned at Google Research in Mountain View with Jason Baldridge and Daniel Gillick working on entity linking.
In Fall 2017: I started at UT and was a TA for an Advanced Data Mining Masters course.
In Summer 2016, I was selected as an Eric & Wendy Schmidt Data Science for Social Good 2016 fellow at the Unviersity of Chicago and worked with SEDESOL of Mexico on improving their distribution of social services.
I obtained a Masters of Data Science at the UPC in Barcelona in July 2015 (masters thesis on automated construction of political networks).
I have a bachelors in Computer Science, Political Science and Hispanic Studies with a Business minor from UT Austin.
A selection of publications and projects, academic, professional and personal.
