Postdoctoral Fellow

Apple, Inc., AI/ML Research
Research Scientist

I am currently a postdoctoral fellow at Carnegie Mellon University (supervised by Jeff Bigham) and a Research Scientist at Apple. I recently graduated with my PhD from the department of Electrical Engineering and Computer Science at UC Berkeley. I was advised by professors Björn Hartmann at UC Berkeley and Maneesh Agrawala at Stanford, and my doctoral work was supported by an NDSEG fellowship. I've previously been supported by a department EECS Excellence Award and a Sandisk Gold Fellowship.

In the summer of 2018, I served as the lecturer for CS160, the UC Berkeley user interface design and development course. Here is the course website.

On one side, a set of extended audio description sentences with their corresponding frames, and in the other column a set of inline audio description sentences and the same frames. The shortened descriptions are as follows: `Shots of lavender in a farmers market' is shortened to `Shots of lavender', `Red flowers against a white house and blue sky' is shortened to `Red flowers', `a courtyard and a pool' is not shortened, `Gaby bikes along a path' is shortened to `Close up of french fries', and `Close up of tater tots and french fries' is shortened to `Close up of french fries'

Research Summary

My research leverages the connections between communication mediums (e.g., spoken audio, multiple video sources, text transcripts) to enable people to fully participate in and better work with digital communication. As a systems researcher in Human-Computer Interaction, I embed machine learning technologies (e.g., NLU, NLG) into new human interactions that I then deploy to test. Using my systems, remote content creators more effectively collaborate, video authors efficiently create accessible descriptions for blind users, and instructors help students to learn and retain key points. To inform future systems that capture what is important to domain experts and people with disabilities, I conduct and collaborate on in-depth qualitative (e.g., AAC communication, memes) and quantitative studies (e.g., 360° Video, VR Saliency). My long term research goal is to make communication more effective and accessible to all.

A slide from a lecture where most text is in black but some of the text has been colored green to represent that it has been spoken by the presenter. There is an image with a squiggly circle brush on the slide, and it has a green border to indicate the presenter described the image.

A YouTube search result augmented with accessibility information. A thumbnail of the video shows a woman in Rome. The rest of the video information reads as follows: Rome, Italy! Tips & Photo Spots by Ruby Keyvani. 5/7 Somewhat Accessible. 76% of the video is speech. The speech is descriptive but contains many visual references (3 per minute). Visual changes occur infrequently (5 shots per minute); few on-screen objects are described (20%).

Screenshot of a tweet by @CDCgov from April 1, 2020 3:55pm: Actions to reduce spread of the virus, such as social distancing, are key to #FlattenTheCurve. 2 of 3 (original tweet link: https://twitter.com/CDCgov/status/1245439600472084486) The tweet contains an image of the common public health infographic about “flattening the curve”, but the tweet did not include alt text for the image. The image shows an example of a common flatten the curve info-graphic. A tall peak indicates the height of the pandemic if left unchecked, and a shorter spread out curve depicts the effects of social distancing efforts.

After a certain point, the number of noteworthy sentences decreases the precision at one -- indicating that lower quality noteworthy sentences add noise rather than value to the prediction.
