Research Scientist @ AI2
CV (as of 7/2021).
I am on github, twitter, google scholar, and semantic scholar.
As of July 2021, I am a Research Scientist at AI2. Previously, I earned a PhD in Computer Science at Cornell University.
I work mostly on natural language processing, machine learning, and computer vision. If you're looking for me, I look something like this (facial hair subject to change):

Things I've Taught
- I was a visiting faculty member at Carleton College in Spring, 2019; I taught two classes: Natural Language Processing and Discrete Math.
INFO/CS 4300 Language and Information, Cornell University, SP 2016
CS4786 Machine Learning for Data Science, Cornell University, SP 2015 for which I received an outstanding TA award!
CS4620 Introduction to Computer Graphics, Cornell University, FA 2014
- Introduction to Computer Science/Graph Theory, Carleton College, FA 2011
Service/Guest Lectures/Other Activites
- Program Committees: ACL 2016, 2017, 2018*, 2019, 2020*; NAACL 2018, 2019*; EMNLP 2017, 2018*, 2019*; EACL 2017; AAAI 2017; ICWSM 2018; CoNLL 2019*; ICML 2020*. For the starred conferences, I was acknowledged as a top reviewer!
- Workshop Program Committees: Black in AI @ NeurIPS 2017, 2018, 2019; Student Research Workshop @ NAACL 2018 ; Workshop on Noisy User-generated Text (W-NUT) @ EMNLP 2018, 2019.
- Two guest lectures (and one "magic" trick) for Spring 2016/2017 CS4300 about my favorite machine learning algorithm: the truncated SVD!
- Spoke at Carleton College's Networks Reading Group where I discussed the role of altruism on Kickstarter.
- Spring Cornell CS4740 Guest Lecture on Topic Models with Xanda Schofield
- Helped with Cornell's annual Expand Your Horizons conference, where some friends and I taught a class on programming (2015, 2016)
- I wrote a TreeLSTM in tensorflow 2; this is a neural network whose topology changes based on each input example.
- I wrote a factorization machine layer in pytorch; for speed reasons, the forward and backward passes are written in cython.
- I implemented Monroe et al.'s "Fightin' Words" algorithm for robustly comparing word frequencies in two corpora. This implementation has been used in several publications, e.g., this and this
- As part of an NSF REU,
I contributed to the implementation of a really (really) fast SVM solver in Kilian Weinberger's lab at Washington University, St. Louis. [now at Cornell!] see Parallel Support Vector Machines in Practice by Tyree, S., Gardner, J. R., Weinberger, K. Q., Agrawal, K., & Tran, J. (2014).
- "A Comparative Analysis of Popular Phylogenetic Reconstruction Algorithms." Undergraduate thesis project/best paper award at MICS 2014: joint work with Evan Albright, Nao Hiranuma, Cody Wang, and Sherri Goings.
I grew up in beautiful Portola Valley, California. I earned a B.A. from Carleton College in 2014, studying computer science and mathematics/statistics. During my time in Northfield, I played ice hockey, hosted a radio show, and was lucky enough to meet and work with a lot of great people. I even returned to Carleton briefly in 2019, this time, as a visiting faculty member! I'm a die hard San Jose Sharks fan, avid consumer (and very occasionally a producer) of electronic music, and, most of the time, a vegetarian (I am no longer a vegan!). During graduate school at Cornell, I was a member of Stewart Little Coop, a cooperative living community of 15 people, I played ice hockey in the Ithaca Hockey Association (and, during summer internships in CA, in the San Jose Adult Hockey League).
