What's the process for starting this poll:
I sent this last year on 9 October.


Hiroshi Takeuchi has nominated  Dr. Yukio Yamamoto for the position of Deputy Chair of the Time Working Group within the Systems Engineering Area.


He has provided the following bio and recommendation:
I am an expert in ground data processing and archiving for deep space exploration at JAXA, with a track record of contributing to numerous projects. In particular, I have been responsible for archiving Japanese planetary exploration data and served as Chair of the International Planetary Data Alliance (IPDA) from 2023 to 2024. Additionally, as a member of the CCSDS Time Synchronization Working Group since its establishment, I have participated in international standardization efforts for time synchronization and contributed to the editing of green books, blue books, and yellow books. Furthermore, I have been involved in developing JAXA's time calibration system, providing the time correction support for various missions including Hayabusa2, ERG, SLIM, XRISM, MMO, and MMX.

Yamamoto-san is actively involving in the CCSDS Time WG recent year.

He took another young JAXA guy to the WG last year, and both of them are wishing to actively work for the WG.

He is an active data scientist and has extensive experience as the chairperson of IPDA (International Planetary Data Alliance) steering committee

as described in his biographical summary.

Therefore I believe he is the right person for the deputy WG chair of Time WG.



Thank you!

Hiroshi
