New paper out today by my #MPIC colleague (and officemate/friend) Sam Nicholson, who looked at the climatic constraints on speleothem deposition in SW Asia - to the surprise of no-one who spends any time thinking about speleothem deposition, it's not straightforward!

My once a decade pavlova, just for the MPIC christmas party. Possibly I would make it more often if I owned beaters and didn't have to whip everything by hand...

I hope the Europeans enjoy a little bit of aussie (not NZ 😉) christmas tradition!

After a fair bit of frustration, our new excimer laser is installed! We have it coupled to an Element 2, and new laser plus sector magnet (rather than quadupole) mass spectrometry is a steep learning curve for me. Nice to spend the afternoon tinkering in the lab though.

Cool new research out today in #Science from #MPIC colleagues - led by Dr. Tina Ludecke. Nitrogen and Carbon isotopes indicate that Australopithecus individuals were herbivores - meaning that meat consumption didn't predate brain development!

Hey brains trust, I am facilitating some #ShutUpAndWrite sessions at #MPIC for the next 6 weeks. We are doing 2 hour sessions. I'm planning ten minutes of 'intention setting', 50 minutes of work, then a 10 minute break to chat, then 50 minutes work.

Any suggestions welcome. I've done pomodoros in the past, but found a lot of the group wouldwork through the five minute break.

Hello guys! A short intro of me:

I'm an #atmosphericscientist interested in #aerosols in complex systems, especially #bioaerosols (e.g., #microbes, spores, biomolecules, etc.) in the earth system and human society. 🦠 🌧️ 🌊 🤧
----------------
- Currently, I'm a postdoc at #MPIC (Mainz, Germany), supervised by Dr. Yafang Cheng and Dr. Hang Su. 🇩🇪

- I study the roles of #bioaerosols in the #atmosphere and the #Earth system.

- I've been developing and/or applying techniques to measure (bio)aerosols, including fluorescence spectroscopy (e.g., #WIBS 🌈 ) and mass spectrometry (#MS, e.g., FT-ICR MS, GC-MS, and AMS 📏 ).

I've also been applying data-mining tools (e.g., machine learning (#ML); #PMF, #PARAFAC, etc.) to reveal those unseen. 💻

Besides, from a wider perspective, I’m also interested in the #chemistry of brown carbon (#BrC), and their impact on the #climate (e.g., the #Arctic #warming). ♨️

And finally, here is my page: https://sites.google.com/view/yuesiyao (still building it 🛠️ 👷‍♂️ )

Beim energieeffizienten natürlichen Lüften schlägt Sachverstand den Hausverstand. Danke @igoe_at und @IBPSC_tugraz, #MPIC und #FUOP
