Preksha Tiwari

Preksha joined Polariton Technologies in August 2022 as an R&D Engineer. She received her M.Sc. degree in Interdisciplinary Sciences with specialization in Physics and Materials Science in 2018 from ETH Zurich. She completed her Ph.D. at IBM Research Europe – Zurich and ETH Zurich in 2021, where she worked on group III-V compound semiconductors integrated on silicon for active photonics. In particular, she fabricated and characterized micro- and nanolasers and high-speed photodetectors for optical communication.

At Polariton she is part of the nanofabrication team which develops scalable processes for plasmonic and photonic structures in high-performance integrated optical devices.

Outside the lab, she likes bicycling, being outside, good food, and stepping out of her comfort zone from time to time.
