Wildfire and Forest Management: Opportunities for HCI Research

Published in ACM Transactions on Computer-Human Interaction (TOCHI), 2026

Interviews with wildfire and forest-management practitioners reveal socio-technical challenges in adopting geospatial technologies — fragmented data, knowledge-sharing barriers, and model-bias concerns — and where HCI can help.

When Borders Blur - Overcoming Political Limits with Computing in Truly Global Societies

Published in Computing Within Limits, 2021

In the face of ecological and political limits, we propose a computational approach to opening borders to migrants in an automated way while ensuring safety for the host nation.

Towards Bilingual Lexicon Discovery From Visually Grounded Speech Audio

Published in Interspeech, 2019

This work presented a multimodal approach to learn bilingual lexicon directly from speech signals in two languages without the need for text by using vision as an interlingua. The approach starts a line of inquiry that can build word level translation between a pair of languages using say youtube videos that have similar objects but with speech in the two languages.

Multivariate Time-Series Similarity Assessment via Unsupervised Representation Learning and Stratified Locality Sensitive Hashing: Application to Early Acute Hypotensive Episode Detection

Published in IEEE Sensors, 2018

We use a deep autoencoder approach to learn representations of multivariate physiological signals that can be hashed and used to compute similarities between patients to assist in predicting critical events.
