People must be easily able to understand and change robot and AI behaviors.
I design tools to enable these interactions.
Trial-and-error reward design is unsanctioned, but the implications of this widespread practice have not been studied. We conduct empirical computational and user study experiments, and find that trial and error leads to overfit and otherwise misdesigned reward functions. Published at AAAI 2023.

Looking at expressive examples can help us better understand neural network behaviors and design better models. Bayes-TrEx is a tool to find these expressive examples. Published at AAAI 2021.

In this work, we adapt a Bayes-TrEx-like framework for the task of sampling representative robot behaviors. Led by Yilun Zhou; published at CoRL (Conference on Robot Learning) 2021.

We look at how cognitive theories of human concept learning should inform human-robot interaction interfaces, especially for teaching and learning tasks. In collaboation with Sana Sharma and Elena Glassman (Harvard). Published at HRI 2022.

We interviewed industry practitioners from startups, government, and non-tech companies about their use and integration of machine learning in developing products. We analyze these interviews with thematic analysis. Collaboration with Aspen Hopkins. Published at AIES 2021.

We design a principled evaluation mechanism for assessing feature attribution methods, and contribute to the growing body of literature suggesting these methods cannot be trusted in the wild. Led by Yilun Zhou, in collaboration with Marco Ribeiro (MSR). Published at AAAI 2022.

A collaboration with Michelle Cone. A distributed system for visualizing the human heartbeat. A webcam, hidden behind one-way mirror, takes your pulse. One leader-elected bulb starts pulsating at this frequency. The leader bulb propogates the message to all bulbs.

A collaboration with Lezhi Li. SwimSwallow is an informal robot made from cheap materials. Video: SwimSwallow
A charging station which compromises privacy by searching for on-device media.
A collaboration with Jo Booth. An implementation of Reynold's classic 1986 flocking algorithm in OCaml.
In 2021-2022, I served as President and in 2020-2021 as Vice President of MIT's Science Policy Initiative. I advocate for using science to inform policy, and for using policy to make science just and equitable. Pictured above with colleague Willie Boag. Not an endorsement for Senator Alexander.
I'm a strong advocate for the inclusion of women and underrepresented minorities in science. In 2019, I served as co-president of MIT's GW6: Graduate Women of Course 6. Pictured above: students from an introductory CS class I taught in Puebla, Mexico.
