I like building models for scientific applications 🚀🤖🧬

2023 -
I am a data scientist at Bayer Crop Science, where I research artificial intelligence (AI) methods for crop improvement. This includes developing advanced models to map genetic inputs at multiple scales to target phenotypes and designing novel genomes through breeding and gene editing techniques to accelerate phenotypic gain for crops in North America.
2019 - 2023
My Ph.D. was focused on high-dimensional surrogate modeling and operator learning as well as transfer learning and multi-domain learning for PDE applications including atmospheric fluid flows, brittle material fracture and modeling plasticity in amorphous solids. My research was generously supported by the U.S. Department of Energy. My adviser was Michael Shields, and I also had the pleasure to work with Michael Falk, Chris Rycroft and George Karniadakis on several exciting projects.

Along the way I squeezed 2 internships at DOE's Los Alamos National Laboratory in 2021 working on generative modeling for LIBS spectra collected by the ChemCam instrument on board the Mars Curiosity rover and at GE Research in 2022 working on applcations of probabilistic machine learning on industrial gas turbines and small modular reactors.
2017 - 2019
MSc at the National Technical University of Athens where I worked on nonlinear dynamics and numerical bifurcation theory applied to biological systems.
2012 - 2017
BSc at the University of Thessaly with a major in civil engineering. My diploma thesis focused on finite element analysis for the design of steel structures.
