Adding Basemaps In Python With Contextily

October 8, 2020

If you work with geospatial data in Python, you most likely are familiar with the fantastic GeoPandas library. GeoPandas leverages the power of Maplotlib to enable users to make maps of their data. However, until recently, it has not been easy to add basemaps to these maps. Basemaps are the contextual map data, like Google Maps, on top of which geospatial data are often displayed.

The new Python library...

Machine Learning in Poverty Measurement

May 11, 2021
According to The Sustainable Development Goals (SDG) from the United Nations, the first goal is to "end poverty in all its forms everywhere". However, a common method to measure poverty is census data or large sample research, which collects data from a large sample size. The cost for conducting these researches is even higher in low-income areas due to the scarce infrastructure (Blumenstock, 2016; Jean et al., 2016; Perez et al., 2019, McBride&Nichols, 2015). As technology develops, scholars and researchers have begun to apply new techniques and massive machine-generated data sources to measure poverty. In this blog, I discuss three general trends in machine learning about poverty measurement and some concerns in the current application.

Imposter Syndrome in Data Science

January 19, 2021

I promised the D-Lab a blog post and then promptly felt unqualified to write it. (I wish that I were kidding.) Thus begins my ironic tale of imposter syndrome in data science.

Who am I?

As a new D-Lab Data Science Fellow and as a doctoral student in Rachel Morello-Frosch’s laboratory in the Department of Environmental Science, Policy, and Management at Berkeley, I work at the intersection of social theory, environmental epidemiology, and geography. Specifically, I research how institutional power manifests in the distribution of environmental monitoring...

Impactful Data Science: What I Learned Through Data Science For Social Good

November 4, 2020

It’s times like these when I like to think about how I can bring together all the technical work I like to do and the impact I want to make. As a Graduate Student in the Energy and Resources Group (ERG) focusing on the intersection of humans and climate, I thoroughly believe that the efforts to create a more just society require work across disciplines to tackle society’s most pressing issues. This led me to join the Data Science for Social Good (DSSG) program at the...

Black History Month, 2021

February 23, 2021

Black History Month, which is observed in February, was established in the 1970s to celebrate the culture and accomplishments of African Americans. Although this designation may seem artificial or unnecessarily limiting (why only one month?), it is useful if it foregrounds the need to better weave Black narratives into the story of the American experience.

While reflecting on Black History Month this February, I remembered how the required reading of Black Culture and Black Consciousness: Afro-American Folk Thought from Slavery to Freedom by the late UCB...

Learning to Code

March 23, 2020

When I was in college I took an introductory programming class and promptly forgot 95% of what I learned. Most of the topics of the homework or coding challenges involved in the class were on topics unrelated to my primary area of interest (language data) and the skills did not seem transferable. My research would never rely on animating a face, so how was it useful?

So, when I was tapped to program for a linguistics project, I didn’t know if I had the skills to be successful in the project yet, or how steep the learning curve would be. And as I spent hours on...

Can Virtual Communities be Archived?

February 23, 2021

When future historians try to piece together social life in the twenty-first century, they won’t be combing through faded newspaper clippings or handwritten letters. They’ll be clicking through digital archives that have stored remnants of our real and virtual lives: email collections, tweets, Facebook messages, maybe even Google Calendar entries.

For the time being, preservation of these records is the burden of the user. If one chooses, they can download their Facebook archive or back-up their emails and photos, and maybe choose to share them with a scholar in the...

We Are Working On Digital Health Social Justice: Here’s Why.

December 1, 2020

If you have ever used a mobile app to track your exercise, train in mindfulness, or collect diet tips, you may have noticed an overwhelming number of apps to choose from.

In 2017, app stores included around 300,000 health and wellness apps, such as meditation or fitness apps. Approximately 200 new apps surfaced daily. In 2020, there are almost 50,000 medical apps. These apps...

Visuals for Everyone: An Exercise on the Importance of Intuitive Data Visualization

March 30, 2021

A couple years ago, I took an undergraduate biostatistics course here at UC Berkeley and vividly remember one of the first discussion section activities on interpreting data and visualizations. From this activity, I learned about why, as data consumers, we must always be aware of not only what visualizations are really representing but also understanding where the data is really coming from. While this might seem obvious, this has been one of the most valuable lessons as an aspiring data scientist/enthusiast. I learned the importance of analyzing and understanding data with...
