I love snow (right now in Tacoma!). And I adore the fact that each snowflake has a nucleation point…which is often a bacterium synthesizing ice nucleation protein. #MicrobialCentrism #MicrobialEvangelist #IceNucleation @microbetv.bsky.social @asmicrobiology @univpugetsound

Here is a swab onto R2A medium from the wall of a student’s plastic water bottle and a close up. Fungus or bacterium? Time and DNA will tell! #WaterBottleBuddies #MicrobialCentrism #MicrobialEvangelist @microbetv.bsky.social @asmicrobiology @univpugetsound.bsky.social

I’m kind of scared I left this outside my lab door. #MicrobialEvangelist #MicrobialCentrism

Current #MicrobialVibes. These are not Doc Martens, sadly, nor hand painted. I’m doing the best I can. #MicrobialEvangelist #MicrobialCentrism @drmartens-official.bsky.social @microbetv.bsky.social @asmicrobiology @univpugetsound

Here is a streak from a sample swabbed from a deionized water spigot. The closer I get, the more microbial diversity I see. And these are just the bacteria grown on R2A plates! #MicrobialEvangelist #MicrobialCentrism @MicrobeTV @asmicrobiology @univpugetsound

I collect lapel pins. Here are my very favorites, mostly of microbe-related topics. #MicrobialEvangelist #MicrobialCentrism @microbetv.bsky.social @asmicrobiology @univpugetsound

My opinion on the microbial world all around us and within us. #MicrobialEvangelist #MicrobialEnthusiasm #MicrobialCentrism @microbetv.bsky.social @asmicrobiology @univpugetsound

Here is a 3D printed hybrid of myself and a tardigrade. We call this a #TardiDoc. It makes me happy. #MicrobialEvangelist #MicrobialCentrism #Tardigrade @asmicrobiology @univpugetsound @microbe.tv

A microbiology student made this for me, complete with hat, several years ago. I treasure things like this from students. I have been very lucky. #MicrobialEvangelist #MicrobialCentrism #LuckyProf @asmicrobiology @univpugetsound @microbetv.bsky.social

An important reminder. #MicrobialPhilosophy #MicrobialCentrism #MicrobialEvangelist @microbetv.bsky.social @univpugetsound.bsky.social @ASMicrobiology

A luminous Valentines Day to @jennifer.j.quinn . #BacterialBioluminescence #MicrobialEvangelist #MicrobialCentrism @asmicrobiology @univpugetsound @microbetv.bsky.social

This is one of my favorite microbiology themed lapel pins. #MicrobialEvangelist #MicrobialCentrism

This says it all. #GramPositiveProkaryote. #MicrobialEvangelist #MicrobialCentrism @asmicrobiology @univpugetsound @MicrobeTV

A Warrior #Tardigrade I commissioned from a very talented friend years ago. I didn’t know it glowed in the dark!#MicrobialEvangelist #MicrobialCentrism #Tardigrade @asmicrobiology @univpugetsound @MicrobeTV

I have always enjoyed showing #Micronauts “who” lives in their water bottles. #DocMartian Chianna demonstrates. These #WaterBottleBuddies are not bad or good. They simply are. #DontFearTheMicrobe #microbialcentrism @asmicrobiology @univpugetsound.bsky.social @microbetv.bsky.social

I am so happy when my students truly *get* #MicrobialCentrism. DocMartian Chianna put it best in today’s research lab meeting. Delighted to share that accurate change in perspective with you all. #StudentResearch #Microbiology @univpugetsound @ASMicrobiology @microbe.tv

This is how I have always felt about microbiology. #MicrobialEvangelist #microbialcentrism #DontFearTheMicrobe @asmicrobiology @univpugetsound @MicrobeTV @GIANTmicrobes

I found this beautiful plastic bacteriophage on eBay. It’s a Japanese toy! Really lovely. #MicrobialEvangelist #microbialcentrism @asmicrobiology @univpugetsound @MicrobeTV

My #MattersMicrobial podcast will continue in 2026, but will be released every other week, in hope of getting more views & listens. I am so very grateful to microbe.tv for the support and belief in this project. So please listen, watch, and spread the #GoodMicrobialWord! #MicrobialCentrism rules!

I send each guest on my #MattersMicrobial podcast a little package of #MicrobialCentrism mementos. Today I received a care package of mementos from the Center for Biofilm Engineering in Bozeman via recent guest Dr Matthew Fields. Very grateful!!! @ASMicrobiology @univpugetsound @microbe.tv

The talented Meagan Moore made this and sent one to me. I indeed aspire to being an explorer of tiny worlds. #MicrobialEvangelist #reinventingmyself #microbialcentrism @asmicrobiology @univpugetsound @microbetv.bsky.social @mooretothepoint

Here is a former student illuminated by bioluminescent bacteria. I’m not artistic by nature, but this is a good shot. #microbiology #bioluminescence #microbialcentrism @asmicrobiology @univpugetsound @MicrobeTV

I adore being among fellow #MicrobialEnthusiasts at #ASMCUE. Several people have come up to me, knowing that I am retiring in June. They tell me they are sad that this is my last ASMCUE. I intend to keep promoting microbiology! You will see me often, promoting #MicrobialCentrism. I promise.

#ASMCUE in San Antonio. Hit me up for a 3D printed glow the dark #MicrobialEnthusiast pin until I run out. Please post and tag me if you get one. #MicrobialCentrism. @univpugetsound @ASMicrobiology @microbe.tv

@jennifer.j.quinn and yours truly getting ready to fly to San Antonio for #ASMCUE. I have pins to hand out! #MicrobialThemedLuggage #RedPunkRockBoots #MicrobialCentrism.

Sometimes I get frustrated I don’t get more attention for my efforts to promote #MicrobialCentrism. But I cannot change people’s minds. So I do the best I can, where I am, with the resources I have available. Anything else is icky ego.

Art I commissioned from Kaitlin Reiss, riffing on the Dean Martin story from the 60s. Someone asked him about Frank Sinatra’s actions in Las Vegas. He replied, “It’s Frank’s world. We just live in it.” So it is with the microbes! #microbiology #microbialcentrism @microbetv.bsky.social

I hope to bring a bunch of these glow in the dark buttons to #ASMCUE in San Antonio. Thank you, @jennifer.j.quinn , who is coming with me! @ASMicrobiology @univpugetsound @microbetv.bsky.social #MicrobialCentrism

Sniff.  My last #Bio350 class at the University of Puget Sound.  Nineteen #Micronauts.  I am so lucky to have been able to do this, and I hope that I can continue to find ways to do outreach and promote #MicrobialCentrism.  #GratefulProf @univpugetsound @asmicrobiology @microbe.tv
