Our April meetup with Data Philly focused on the increasingly popular topic of Open Science. See below for the article that R Ladies Philly members Alice, Karla, and Amy co-wrote! This article originally appeared on Philly. What is open science? It’s like open data, but for research. Organizers of the R-Ladies Philly meetup offer an explainer based on talks from their most recent meetup. Many are familiar with the concept of open source in software development, but what is open science?


In February and March, R-Ladies Philly continued a longstanding community data project with the Philadelphia Animal Welfare Society (PAWS) - Philly’s largest no-kill shelter. Last year, we helped PAWS analyze data from volunteer engagement to identify patterns associated with continued volunteering. This year, we worked with PAWS to understand important facets of their sheltering system, including 1) animals’ trajectories at PAWS, 2) the adoption process, 3) geospatial patterns of adoptions, and 4) public engagement via social media.


Our January meetup marked an important event in R-Ladies Philly history - our first ‘birthday’! We honored this occasion by celebrating what our community has achieved over the past year, and planning for an exciting 2019. Recap of our first year Alice and Karla started off by reiterating the founding principles of R-Ladies Philly: to create a welcoming, accepting, and representative community for R users in the Philadelphia area who espouse our values of diversity and gender equity.


We collaborated with Women in Kaggle Philly to provide an Introduction to Machine Learning (ML). ML is the science of getting computers to learn from data without explicit programming. ML has led to advances in speech recognition, tumor identification, self-driving cars, and many other arenas. You probably interact with ML every day! This meetup featured a lightning talk introducing some key concepts followed by a hands-on Kaggle competition tutorial. A brief introduction to Machine Learning Tamera Lanham, a data scientist at Elsevier, gave a lightning talk introducing ML.


Geographic Information Systems or GIS are specialized technology used for spatial data that require mapping. In our November meetup, R-Ladies Philly member and GIS Specialist Mary Lennon introduced R-Ladies Philly to manipulating and plotting spatial data from our favorite city (Philly!) in our favorite language (R!)! How can we access and store spatial data? First, Mary explained that GIS data can be stored in different formats including Shapefiles, GPX, and GeoJSON.

Darina Chudnovskaya, MSc

Darina is a data analyst at a hospital in the Philadelphia area. She uses R to run statistical tests and build models for epidemiological studies with the goal of developing patient interventions for disease prevention. She grew up in Philadelphia. Darina joined R Ladies Philly to meet other R enthusiasts.

Karla Fettich, PhD

Karla works as Head of Algorithm Development at Orchestrall, where she leads behavioral data analytics efforts and predictive model development for healthcare IT innovation. Currently, Karla uses R to create a new product that uses machine learning and predictive analytics to serve as a companion to nurse aides in their care for the elderly. Originally from Romania, Karla completed her B.A. in social and cognitive psychology at Jacobs University Bremen in Germany, her M.A. in social sciences at the University of Chicago and her Ph.D. in psychology and neuroscience at Temple University in Philadelphia.

Amy Goodwin Davies, PhD

Amy is a linguist-by-training and a data scientist. In particular, she is excited about developing her skills in text mining and natural language processing. Amy completed her PhD in Linguistics at the University of Pennsylvania, where her research focused on the grammatical representations involved with word recognition. Amy is originally from the UK. Before moving to Philadelphia in 2012, she completed her undergraduate studies at the University of Edinburgh.

Katerina Placek, MSc

Katerina is a PhD candidate in Neuroscience at the University of Pennsylvania. She uses R in her research to statistically evaluate genetic risk factors for frontotemporal disease in amyotrophic lateral sclerosis and to visualize results. Katerina started an R-Learning group in her lab at the University of Pennsylvania, and was recruited by Alice to help start R-Ladies Philly!

Alice Walsh, PhD

Alice is a computational biologist who works in pharmaceutical drug development and has lived in the Philadelphia area for the last ten years. She uses R to transform biomarker data from patients into useful insights that can help doctors make better decisions. Alice was inspired to start an R-Ladies chapter in Philadelphia after seeing a video of another R-Ladies meetup online.
