Matthewos Tefferi has a diverse work experience in the field of research and engineering. Mattewos started their career as a Project Engineer at Ethiopian Electric Power Corporation, where they focused on simulations of future grid expansions, evaluating transmission system upgrades, and project management.

Mattewos then worked as a Research Intern at Nexans, where they conducted research and development on HVDC extruded cable insulation technology. Mattewos used finite element methods and time stepping algorithms to analyze transient nonlinear coupled field problems. Mattewos also collaborated with the product manager to explore new materials for cable manufacturing.

Matthewos later joined the University of Connecticut as a Graduate Research Assistant during their PhD. Mattewos conducted extensive research on solid and liquid dielectrics, DC cable insulation design, Wet-Mate connectors, and high energy density capacitor technology. Mattewos specialized in modeling transient nonlinear finite element analysis with coupled electrical and thermal fields.

Currently, Matthewos is employed as a Research Engineer at G&W Electric Co. Their role and responsibilities at the company are not specified in the provided information.

Matthewos Tefferi completed their education in a chronological manner. Mattewos first attended Mekelle Institute of Technology from 2006 to 2010, where they obtained a Bachelor of Science (B.Sc.) degree in Electrical and Electronics Engineering. Mattewos then pursued further studies at Chalmers University of Technology from 2011 to 2013, earning a Master of Science (MSc) degree in Electric Power Engineering. From 2014 to 2018, Matthewos attended the University of Connecticut and obtained a Doctor of Philosophy (PhD) degree in Electrical Engineering, specializing in Electrical Insulation Research Center. Additionally, they have also obtained certifications in Root Cause Analysis from Illinois BIS in December 2019, as well as Electronic Materials and Devices and Introduction to Solid State Chemistry from edX, although the specific completion dates for the latter two certifications are not available.
