2022 in numbers

2022 is over now, and COVID-wise things are somewhat getting back to normal. Our group started to return to the office most days. As highlight of 2022, CISPA had a quite successful external scientific evaluation in November. Metric-wise (continuing my tradition), the year went as follows. As of now, first week of January 2023, my publications reached ~5500 citations according to Google scholar (vs. ~4200 at this time last year/ 3100 two years ago/ 2100 three years ago/ 1400 four years ago/ 1000 five years ago). So growth has slowed a bit, but so far I’m hoping to reach the 2021 citations numbers when some missing citations are added for 2022. Google scholar currently lists ~95 publications (vs. 90 last year, most peer-reviewed), and 2 US patents and several pending ones. Our first GPS paper currently has 581 cites (after 495 last year), in total 15 papers have >100 cites. My h-index has increased to 39 (from 34, my i10-index is currently 65, from 57 last year. Unfortunately, our GPS paper did not get a test-of-time award at CCS 2022, as the organizers chose to only award one paper from 2011 (compared to two in 2012), and that was Android permissions demystifyied with almost 2k citations. I feel that our paper’s citation trajectory suggests an even better long term impact, with numbers still rising yearly after 10 years.

Semantic scholar lists 4380 citations and 105 publications. They still indicate how many papers were strongly influenced by my work (332), compared to 203 in previous year.They don’t list which authors were most influenced any more. I supposedly had 200 co-authors overall.

Scopus lists 79 publications, ~2871 citations, h-index 28, number of co-authors: 147 (136 last year). Overall they seem to have index around half of the number of documents that Google scholar has access to.

In 2022, I didn’t chair events, but I continued to serve as area editor for IEEE Transactions on Information Forensics and Security (T-IFS), the highest ranked security journal. I will be chairing WiSec in 2023, so some preparatory work for that was done in 2022 already (e.g. first round of submissions in November).

Other numbers for 2022: Github lists 201 commits to repositories, mostly for my BMBF project Kamaeleon. I received 10100 mails on my university accounts (after removal of spam). Per working day, that would make around 41 (previous year: 42) mails. I sent 1663 mails (~7 per working day, last year 10). Both numbers have gone down a bit from 2021, maybe because I didn’t chair events.

My twitter account currently follows 108, has 357 followers. I set up a mastodon accound at well ( https://infosec.exchange/@notippenhauer), but am not very active on either.

My total Youtube stats: 8k views (2.2kh of watchtime) on ~65 videos total (most from the lectures I gave in ‘20-‘22). 21 subscribers. Apart from video of keynote talks, other videos are private, so I won’t share them here. ~55 likes total (100% like ratio).
