Biography

Tworit, originally from Odisha, India, earned his Bachelor of Technology (B-Tech) degree in Instrumentation and Electronics Engineering from The College of Engineering and Technology, Bhubaneswar, in 2016. Following this, he worked at Robert Bosch, India, from 2016 to 2018 as an On-Board Diagnostics (OBD) Calibration Engineer in the automotive sector, particularly focusing on passenger car applications.

He subsequently pursued a Master of Science (cum laude) in Electrical Engineering, with a specialization in Telecommunication and Sensing Systems, which he completed in 2020. His MSc thesis carried out in collaboration with the Netherlands Institute for Radio Astronomy (ASTRON), was centered on the computationally efficient design of conical horn antennas for the Square Kilometer Array (SKA) project.

In February 2025, Tworit was awarded his Doctor of Philosophy (PhD) with the thesis titled "On Doppler Processing for Fast-Scanning Weather Radars" from the Microwave Sensing, Signals, and Systems group at TU Delft. Currently, he holds a position as a postdoctoral researcher, where he is engaged in the formulation of electromagnetic inverse problems for PHased Array Radar for Atmospheric research (PHARA) and the development of novel signal-processing algorithms for atmospheric parameter retrieval.
