Data Scientist Researcher

• Built and conceptualized two state-of-the-art statistical models to provide estimates of population-genetic metrics from molecular data using iterative optimization procedures, resulting in more than a 30% decrease in data collection costs and a 10% increase in accuracy • Managed and led two projects for creating statistical pipelines to provide improved estimates of population genetic metrics by applying analytical & heuristic approaches, leading to accurate (unbiased) results and more than 20% increase in precision across different ranges of parameters validated by Monte-Carlo simulations • Developed the R package MLMOI as a tool for automatic data pre-processing (cleaning, preparation, and wrangling) of various molecular data formats and applying statistical analysis • Preparation, creation, and presentation of the published work: published two peer-reviewed papers in PLOS One and bioArxiv ; held altogether four presentations at the following conferences: ASTMH , German Mathematical society (awarded the best presentation at the AIMS Minisymposia), NNWK (awarded the best scientific paper) • Outlined and structured course syllabus in topics statistics & probability, along with supervising more than 50 students in using R to implement various statistical approaches and data visualization
