2020 in numbers

What a year 2020 was! I spent more than half of the year in home office (mostly with my kids at home as well). I contributed to the COVID19-Scenarios project, DP3T, and the German Corona Warn App (used by ~20M Germans to date). Now follows some numbers on 2020, continuing my tradition. As of now, first week of January 2021, my publications reached ~3100 citations according to Google scholar (vs. ~2100 at this time last year/ 1400 two years ago/ 1000 three years ago/ 700 four years ago). Google scholar currently lists ~80 publications (vs. 72 last year, most peer-reviewed), and 2 US patents and several pending ones. Our first GPS paper currently has 427 cites (after 345 last year), in total 7 papers have >100 cites. My h-index has increased to 29 (from 26), my i10-index is currently 50, from 39 last year.

Semantic scholar lists 2584 citations and 95 publications. They still indicate how many papers were strongly influenced by my work (169), compared to 113 in previous year. Authors listed as most influenced (unclear what that means) by my work are: Jianying Zhou (72), Mujeeb Ahmed (72), Sridhar Adepu (70), Aditya Mathur (69), Martin Ochoa (59).

Scopus lists generally lower numbers (e.g. only 63 publications, ~1558 citations, h-index 21), but they provide a number of co-authors: 119 (113 last year).

Other numbers for 2020: Github lists 697 commits to repositories (after 52 in 2019), as I started to use Github again for contributions to DP3T, and Covid19-Scenarios. I received 10832 mails on my university accounts (after removal of spam). Per working day, that would make around 42 (previous year: 20) mails. I sent 2167 mails (~10 per working day, last year 5). Both numbers have doubled compared to 2019 statistics, due to my growing group at CISPA, and involvement in projects such as DP3T. While we still use Mattermost to communicate with others at CISPA, the work-from-home situation now introduced various other chat systems I need to keep track of.

My twitter account currently follows 81, has 214 followers, and 113 tweets.

Due to the homeoffice situation, I am a Youtuber now: 2.7k views (804h of watchtime) on 33 videos total (most from the two lectures I gave in 2020). 13 subscribers. The videos are private, so I won’t share them here. 26 likes total (100% like ratio).
