About Me
Experienced chemist (Chemical Engineering PhD) who knows laboratory tasks that turn into Data Scientist with 4+ years of broad-based experience in building and agglomerating datasets. Understanding complex measurement systems with a broad systemic view. Proficient in predictive modeling, data processing, and data mining algorithms, as well as scripting languages, including Python and Matlab.
Resume created on DoYouBuzz
Experiences
  • Build predictive models using various mathematical tools to quantify (PLS-DA, SVM-DA) and identify bacteria according to their spectral response (PARAFAC, SVM).
  • Demonstrate knowledge and execution of a new procedure (ANN, ML, XGBoost) to determine which antibiotics a specific organism is susceptible to antibiotics (Antimicrobial Susceptibility Testing).
  • Utilized analytical and technical expertise to provide insights and proposals to support engineering and laboratory decisions (PCA, CLS, MLR).
