- ACSM Announces Paper of the Year Awards for Scientific Journals
- We were back at the Columbia University Data Science Day in Spring 2023, held at Lerner Hall on campus. I have a very personal connection to this annual event and always feel thrilled when we get to present our research with this community. This year, I presented some of our latest methodological work on functional data analysis for clustering wearable data for characterizing heterogeneous, longitudinal physical activity patterns.
- I was awarded an R01 grant by the National Institutes of Health (NICHD) in September. This project will investigate a functional data analytic framework to design and evaluate mHealth measures of pain, quality of life, and treatment response using patient-generated health data with high complexity and temporality. This study will test a novel application of Distributed Lag Models (DLMs) in this mHealth context to estimate “critical windows” of tracking analogous to the “window of susceptibility” (Further project details).
- I spoke at the 2022 New York R Conference in June! I have been attending these events for several years so I was thrilled to be invited as a speaker. The event was held during June 8-10th as a hybrid conference. The recording of my talk on functional clustering using wearable data is available on youtube.
- I presented some of my latest work on integrating functional data methods with unsupervised learning for clustering daily physical activity trajectories at DSI’s Annual Data Science Day on April 6th, 2022.
I had the great pleasure to join the Symbiosis Competition judges panel at this year’s Imagine Science Film Festival. The event was held October 15th-22nd in NYC. Symbiosis is where I met my co-director and partner in crime Camille Hollett-French last year. Moreover, I got to meet the festival directors and organizers in-person for the first time this year. Overall an exciting time. Congrats to this year’s Symbiosis winners Arianna and Rashu!- ENDOMIC has been announced among the official selections by the 12th Awareness Film Festival! We are thrilled to be a part of this festival, whose mission is to inform and inspire audiences by spotlighting film-makers committed to making positive change throughout the world. This year’s event will be held October 21st-November 1st in 2021 Los Angeles.
- My presentation on digital health applications of unsupervised learning at the 2021 Annual DSI Data Science Day is now available online.
- A piece by Karina Alexanyan on my recent collaboration on ENDOMIC as inspired by my research is now live. It was great pleasure to chat with Karina and I am excited about how the piece turned out.
- My latest work on digital phenotyping of sleep using unsupervised machine learning was presented at the DSI Health Analytics Poster Session was held on April 2nd, 2021.
- Responsible Investor magazine recently covered (pdf version here) a project conducted by Rights CoLab, one of our Data for Good collaborators.
- With my colleagues at Columbia, I was recently awarded seed funds from the Data Science Institute to study digital sleep phenotypes and examine the associations of daily exposure to minority stressors (such as experiences of discrimination and anticipated discrimination) with sleep health among Black and Latinx sexual and gender minority adults.

- Speaking at the DSI Summer Career Webinar Series
- Virtual Data Science Day 2020 at DSI
- In June 2019, DSI participated in the Annual Columbia Alumni STEM Day for the first time. I organized and led a team of students representing the DSI at this event to create an interactive project that aimed to introduce kids to the field of data science, help them better understand how to visualize and interpret data, put it into context and disseminate their findings. We developed an interactive data science education tool that implements scientific methodology steps and aims to improve graph literacy in young children. I later led workshops held at Teachers’ College for elementary school teachers based on this tool.
- Leading Workshop on data literacy skills in K-12 classrooms
- This project later led to a white paper co-authored with Monica Chan, one of the doctoral students involved in the project, for which we won the Computing Community Consortium White Paper award for open source data science education:
- “Children are natural data scientists”
- Guest Post on Thrive Global: “Making your wearables work for you“
