Christos Tsolakis

Christos Tsolakis, Ph.D. is a senior R&D engineer on Kitware’s Scientific Computing Team located in Clifton Park, New York. He develops visualization algorithms in addition to maintaining and expanding visualization toolkits and applications, including the Visualization Toolkit (VTK) and ParaView.

Prior to joining full-time, Christos was an R&D scientific software developer intern at Kitware during the Summer and Fall of 2020. During these periods, he had the chance to work and contribute to VTK and Paraview as well as familiarise himself with the capabilities of SMTK.

In 2019, Christos’ paper “Anisotropic Mesh Adaptation Pipeline For The 3D Laminar Flow Over a Delta Wing,” won the best presentation award in the General Engineering track at the Modeling, Simulation, and Visualization Student Capstone Conference in Virginia. He was afterwards invited to present the same paper at the 2019 MODSIM World Conference.

Christos was selected to participate in the 2017 Argonne Training Program on Extreme-Scale Computing. This highly competitive program is part of the Exascale Computing Project, a collaborative effort of the U.S. Department of Energy (DOE) Office of Science and the National Nuclear Security Administration (NNSA), to provide intensive training for designing, implementing, and executing computational science and engineering applications on current high-end computing systems and the leadership-class computing systems of the future.

Christos received his Ph.D. in computer science from Old Dominion University in 2021. In 2014, he received his bachelor’s degree in mathematics from the Aristotle University of Thessaloniki in Greece.
