Christina Schenk

Postdoctoral Fellow at Carnegie Mellon University

After receiving my bachelor's and master's degree in applied mathematics in 2011 and 2013 from Trier University (Germany), I started working as a scientific assistant in the research group of Prof. Dr. Volker Schulz on PDE-Constrained Optimization at Trier University in 2013. Throughout this time, I was also pursuing my Ph.D. in the area of Modeling, Simulation and Optimization of Fermentation Processes. I successfully defended my doctoral thesis on Modeling, Simulation and Optimization of Wine Fermentation on February 1, 2018.
Subsequently, I joined the research group of Prof. Dr. Lorenz T. Biegler at Carnegie Mellon University in Pittsburgh, PA (USA) in March 2018. Here I mainly work on large-scale variance and parameter estimation for pharmaceutical processes in collaboration with Pfizer Inc..

Research

  • Algorithm and software development for variance and parameter estimation of reaction kinetics from spectroscopic data coming from pharmaceutical processes
  • Modeling, simulation and optimization of fermentation processes for the production of biogas and wine
  • Economic nonlinear model predictive control with parameter and state estimation for wine fermentation
  • Integro-differential equations, systems of weakly hyperbolic differential equations or respectively reaction-advection equations
  • Population balance models
