@leeselab.bsky.social
Professor at University of Duisburg-Essen 🇪🇺🇩🇪 tweeting mostly about the work we do in our Aquatic Ecosystem Research Group. A lot of DNA / eDNA & popgen stuff on streams & automated biodiversity monitoring approaches.
Every year a highlight & intense period: Our molecular ecology module! We train advanced Master students on how to apply DNA & #eDNA #metabarcoding to assess riverine #biodiversity.
Long #Day1 today as we sampled until 19:30. Motivation: 10/10. Tomorrow: to the lab! @unidue.bsky.social @sgn.one

Our team @unidue.bsky.social turned 🔟 today & I found myself in a spontaneous celebration event.
Really happy & grateful to work here with such a great bunch of talented & nice people - connected to our collaborators around the 🌎. Life could be worse. Weiter geht‘s. ☀️Maybe more lab work next 🔟 ?

Very good to see our @pensoft.net journal @mbmg.pensoft.net continues to receive good CiteScores and also now the first #ImpactFactor with a good value of 3.1 ☀️
While I personally don’t care much about these metrics I know they are really relevant for many institutions. Thus: very happy about this!

One advantage of 2️⃣ corona infection: time & fit enough to update lectures that urgently require an update. E.g. introduction into high-throughput sequencing. Crazy how this field develops. Good old MiSeq seems to be one of the few constants. Very happy about the options we have. @unidue.bsky.social
