Proud of Ben Ma, stellar post-doc for 3+ years, thru COVID, with successful proposals, impactful papers, careful mentoring, moving us into new important research @CUEVEN @cuengineering. Congrats starting your TT position @unrengineering ! well done. We will miss you in Boulder!

Big years for the Emma Awards! My PhD students Emma W (2022) & Emma P (2023) received @awwa Philip Singer Scholarships. Phil was my academic great grandfather, their g-great academic grandfather. Very special for our group-We miss you Phil! @CUEVEN @CUBoulderCEAE @UNCpublichealth

April Fools pranks-this was one of the best. My grad students hacked our lab web page and changed our profiles to our pets pics and hilarious bios. I love this and think we should keep it! post-dog-toral researcher Charlie, Dumpling's Meow-ster's and Gil's Bark-chelor's degrees

Thanks @yinyinye and @Ning_Dai_Lab @UBengineering for a great visit/invitation to give seminar – glad it was well received! I had a packed day with you and it was really great - you have an excellent program, with happy students & faculty. I look forward to following UB EnvEng!

It was one of the best seminars I attended at UB! The rare one which held our attention from start till end & I could see ppl taking notes left n right including myself! Looking forward to see how this new UV technology pans out commercially in near future! @waterprof

@stukhan @CUEngineering @CUBoulderCEAE We only did one type of toilet - this was unfunded but too cool not to do, once we realized the potential with the laser set up that Crimaldi has for fluid mechanics. We hope to continue with other toilet types and other ideas for better/more data

[Karl Linden @waterprof]

Fluid mechanics of the aerosols emitted from toilet flushing. Our new “toilet paper” is out today led by @CUEngineering @CUBoulderCEAE Prof John Crimaldi and his team of laser geeks. Visualize your next toilet trip. https://t.co/oW5fmJN0eG

[Karl Linden @waterprof]

@WingedWheel84 @CUEngineering @CUBoulderCEAE We need to do that study and also with typical household flushes. Looking for more funding!

[Karl Linden @waterprof]

@GeekAndDad Thanks! Yes - we are looking for some funding to do more toilets and develop best practices. Very interesting about the oncological flushing practices! makes sense.

[Karl Linden @waterprof]

What a wonderful visit to UBC and to finally meet some of my extending academic family. Thanks @realSaraBeck @_Chintalapati_ @MadjidMohseni @rachelcscholes for meetups, dinner and inspiring so many amazing students I met at UBC

[Karl Linden @waterprof]

Its that time in your career when some of your former grad students and their grad students meet up at a conference, bond, and send you a photo :) #lovethisjob #proudmentor #academiclife #LindenResearchGroup @IntlUVAssn @water_micro @realSaraBeck @hadasmamane1 @danapousty

[Karl Linden @waterprof]

Great to meet up with 🇨🇦 students and colleagues this AM and Thanks to @FulbrightCanada for supporting increasing US-Canada collaborations through my Fulbright Canada Research Chair this semester. #WASHCanada led by @PH2E_UVic is an awesome network!

[Kelsey Shaw 💩 @kelseyshaw214]

Wow! What a great first #WASHCanada 🌊🇨🇦seminar this morning by @waterprof talking about "thinking outside the treatment plant" with UV disinfection for small and distributed systems. If you missed it - check out out YoutTube Channel https://t.co/XMkJzmM4K3

[Karl Linden @waterprof]

Excited to work on this EPA PPP project idea developed by Matt Bentley - will be looking for motivated undergraduate students to join the team @CUEngineering @CUEVEN

[U.S. EPA Mountains and Plains Region @EPARegion8]

Congrats to the @cuengineering student team on being 1 of the 16 teams to receive People, Prosperity, & the Planet (P3) awards! Their $25k award will be used to develop a #DrinkingWater risk assessment tool. Read more about: https://t.co/a6fkWK4PDJ

@mcbeath2o @mass_cee @UMassAmherst Congrats Sean! This @mass_cee will be a great place for you to grow your research and teaching - excellent faculty, great program and beautiful location! Look forward to collaborating ASAP!

[Karl Linden @waterprof]

@Y_Rodriguez017 @ConversationUS Thanks Yoni - nice to meet you and talk with your @uwsph class about benefits of UV for public health!

[Karl Linden @waterprof]

@flrosario A student I was mentoring last year got all excellents, but only 2 reviews and no award or honorable mention. We went back and forth with NSF for months to get an explanation or some info: response was: stuff happens in panels and thats not recorded, try again next year.....

[Karl Linden @waterprof]

@Straub_Tony Congrats Tony! Well deserved. Proud to be your Colorado colleague @CUEVEN @CUBoulderCEAE

[Karl Linden @waterprof]

The intersection of solid waste and art in the “Throwns of Waste” final presentations in @drmansfeldt solid waste class @CUEVEN @CUEngineering - can we get any cooler in @CUBoulder at the CU Museum of Natural History - Love it!

[Karl Linden @waterprof]

Eloquent and fascinating discussion on How Professor Sherri Cook Uses Sustainable Water Treatment Systems https://t.co/2Sn5T2W254 via @YouTube -honored to have her as a colleague and friend @CUEngineering @CUEVEN - ~2 min to check it out!

[Karl Linden @waterprof]

@DrPieterPeach @DavidElfstrom Most materials absorb the deep UV wavelengths that are used in disinfection, but it depends on the material used. paint should absorb but aluminum will reflect. Certainly any upper room UV 254 nm application should not be designed to have light reflected back toward people.
