Data Science

During my PhD, I took a deep dive into the world of data science. This came natural to me, as I already had previous experience in coding from my web development days. However, I learned quite a lot about how to deal with data, including how to:

  • retrieve and filter data from databases or dataframes
  • clean, filter and transform data
  • export acoustic information from annotated audio files
  • statistically analyze data using different models and techniques, e.g. linear mixed effects regression modelling
  • visualize data

Most of these were accomplished using R and R packages (e.g. dplyr, ggplot, lme4, etc.), SQL, and Python. I am eager to expand my skills on data science in regards to natural language processing and machine learning, especially using Python, and I'm currently learning to use the Python packages pandas, spaCy and plotnine.

Media design and development

From 2005 to 2011, I worked as a professional media designer and web developer. Though the world of web development has changed dramatically, I still have a high affinity to web and media design. Having studied these fields extensively, I have a professional understanding of:

  • layouting and presenting data and information, both online and offline
  • user-centered design approaches
  • graphical manipulation in Adobe Photoshop
  • coding in HTML/CSS/JS
  • deployment and usage of content management systems
  • layout
  • InDesign
  • Photoshop
  • Figma
  • HTML
  • CSS
  • PHP
  • UX
  • user centered design
  • design thinking

Soft Skills and Other Skills

  • I am a maker and when I see things that need to get done, often take it upon myself to manage and complete these projects. This characteristic transcends to many aspects of my professional and personal life. For example, in my free time, I sometimes like to create player aids for board games in InDesign, because I feel like players will benefit from those.
  • I am a team player - I worked with many different teams, both as a team leader (leading a group of student assistant on annotation tasks) and as a team member (being part of a larger research unit).
  • I am a very helpful person, and have a gift of recognizing when people are in need of support.
  • I am skilled at teaching and presenting complex content to learners, as well as to equals and superiors.
  • I am a very quick learner, and I acquired most of my coding and data science skills "learning by doing".
  • presentations
  • creativity
  • attention to detail
  • self-learning
  • teamwork
  • project management
  • communication
