Born in Japan, grew up in America and Israel, having also lived in Germany, just returned from London, and currently residing in Tokyo. I’m quite proud to say that I am a citizen of the world!

Currently working for ACDI/VOCA, an international development NGO, as a Data Scientist. For the past 5 years I have been doing work as both a reporting analyst and a software developer in R and SQL to improve ACDI/VOCA’s data pipeline and create R packages, reproducible reports, dashboards, Shiny apps to communicate how our projects worldwide are progressing. I also manage our entire R code base that includes various ETL scripts, R packages, and software applications for data collection/management. I am also very involved in the R community (in Japan through Tokyo.R & internationally) through my volunteer work as an editor on the RWeekly newsletter (since April 2019). In 2020, I also did some work as a soccer analytics consultant for 11tegen11.

Interested in doing data analysis/visualization with R and SQL for NGOs, charities, non-profits (#DataForGood).

I have a MSc. in Industrial-Organizational and Business Psychology from the University College London (UCL). During the MSc. my main research interests were in consumer behavior, behavioral economics, and influencing/motivating behavioral change for the public good.

My interest in R comes from my belief in the need for more reproducibility and accountability in psychological and consumer research that can be attained by using R, GitHub, and other open-source software/tools to facilitate increased transparency between researchers and the general public. My main strengths in R are in creating data science tools (R packages, dashboards, data pipeline scripts), data wrangling, visualization, and more. Many examples of which you can see throughout my blog posts and my viz gallery!

You can learn a bit more about my hobby/work in R and in soccer analytics from interviews I did here and here.

Other interests/hobbies include Soccer/Football, Star Wars, and of course - Data Science!

  • MSc Industrial-Organizational and Business Psychology: University College London, UK
    • Dissertation title: “Emoji and the Implicit Association Test for Uncovering Implicit Attitudes Toward Brands and Different Race Advertisement SpokesEmoji”
    • Supervisor: Dr. Dimitrios Tsivrikos
    • Abstract: “The present study combines the usage of the Implicit Association Test (IAT) in consumer research with emoji, a set of graphics used increasingly throughout computer-mediated communications including marketing and advertising messages. Study 1 demonstrates that emoji can be used as the valence attributes in a simple IAT categorization task. Study 2 goes further by demonstrating the convergent validity of the IAT using emoji valence attributes with explicit attitude measures in a situation where consumers had no reason to hide their beliefs. Study 3 demonstrated the contrast between explicit and implicit measures towards advertisements featuring Black and White skin tone emoji as advertisement spokespersons (SpokesEmoji) that revealed divergent responses in Black and White respondents. Overall, the results support the usage of pleasant and unpleasant emoji as IAT valence attributes. In addition, the IAT’s ability to test consumer attitudes toward different racial spokespersons represented by emoji is a benefit to researchers in marketing and advertising, an area where the usage of emoji continues to grow.”
