Workshops arranged/organized/Invited:

1. Title: 6th IEEE ICEE (Hilton, Bangalore, December 12th – 14th, 2022): I was invited to put a talk on "Temperature Dependent Band Gaps and Giant Excitonic Binding Energies in Novel 2D beta-phase Nitrogen Arsenide and Nitrogen Antimonide”. The conference was arranged by IEEE EDS and IISc Bangalore.
 
2. Title: First Workshop on Electron Devices 2016 (WED’16): I was an organizer of the IEEE Workshop on Electron Devices 2016 (WED’16) (the first workshop being organized by the newly formed IEEE EDS UP chapter meant to promote students, young professionals and women in science and technology) at IIIT-Allahabad. The focus of this workshop was to discuss the recent advancements in electron devices with their well-recognized and promising applications. It covered the topics range from device modeling to basics of emerging electron devices and their potential applications as per the current requirements. The workshop WED’16 consisted of invited talks in the related areas by experts from IITs and other premier institutes and research centres of the country as well as representatives from industry and provided an opportunity for participants to discuss various aspects of emerging electron devices, disseminate work in progress, and promote new ideas in the field.

3. Title: "Workshop on Compact Modeling" at IIT Kanpur on 3rd March, 2017: I acted as an invited fellow to delivered a lecture on "Role of Feynman diagrams in energy band structure of materials - A post density functional theory approach". The workshop was arranged by Professor Yogesh Chauhan at IIT_Kanpur during March 2017.

4. Title: International Workshop on Physics of Semiconductor Devices for December 17-20, 2019, at Kolkata, India: I delivered a talk at International Workshop on Physics of Semiconductor Devices for December 17-20, 2019, at Kolkata, India on the excitonic affairs in two-dimensional semiconductors.
