Been a while, but I’m glad my feed is still filled with a strong community of scientists!
Wanted to share this amazing honor from ASCP as one of their 2025 40 Under Forty honorees. And also to show off this mini scientist my cousin got me. My tchotchke shelf at work is growing ☺️ #ClinMicro

I always look forward to ASM Microbe, but 2025 was particularly special because it was hosted in my neck of the woods. I hope my colleagues got to see everything that is beautiful about Los Angeles! #ClinMicro #ASMicrobe2025

Is #WormWednesday a thing?
Cuz this is my favorite parasit. consult. Again, I don't think it came as a consult, more like Path sharing "look what we found!!!"

Not so gentle reminder that CDC recommends the use of antimicrobial susceptibility results to direct antibiotic therapy against Shigellosis if treatment is warranted.
PCR isn't always enough, guys and gals!

Spent 5years in grad school studying antibodies, but I still have to draw it out for myself. 😅🤭 FYI: that's how you properly draw an antibody 😂 #ClinMicro

Still one of my favorite photos! I don't even think this came as a consult, more like Path sharing "hey look what we found!" You can actually see fully formed and preserved sporangia 😯 #MycologyMonday #ClinMicro

🙄 ironically, my job security relies on people thinking they don't need us. the difference is whether we do it to prevent or to control. #ClinMicro #IDSky

To go full circle, this was the last consult I had as a fellow:
Immunocompromise patient with pretty extensive deterioration of her nasal cavity. Bx of lung tissue (?) sent to path.
Would be impressed by anyone's thoughts. #ClinMicro

Prepping my slides to teach Medical Mycology to med students and I'm coming across old cases. So I'm gonna populate my page with some cool photos!
This was my 1st consult as a fellow: peds with AML on chemo. Punch bx of lesion found between toes sent to path.
Thoughts?? #ClinMicro
