Rainy morning, 3 wanted to play with playdoh. Am I thinking of work too much??

We hung up this photo on the landing of our staircase and this guy brings me joy every time I climb the stairs. So - I thought I’d share! #happymoray #Aruba

The Pfenniger lab is hiring! We are looking for an experienced research tech who is interested in cardiac research. Molecular biology skills preferred. Come learn about atrial fibrillation, and help us figure out why it happens! Job ID 53152 careers.northwestern.edu/psc/hrnu_er/...

Yes, pigeons!!! Here are some I drew with my toddler as a collaborative project (added challenge is using random pens/pencils that are in toddler’s art supplies)

I love when science investigates children’s books. Eric Carle describes this in A House for Hermit Crab!

Basic science research tools don’t always have to be high-tech/expensive. Rice cooker ftw!

Today I worked for 16h straight. Why? For science. I am trying to understand how heart failure promotes #AFib. Sometimes this is best done with single atrial cells, in a dish (here with a calcium-sensitive fluo dye). Doing this right takes time. NIH used to fund this type of science. Now? Who knows.

Morale in research labs is at an all-time low. But: we found stickers. Animal stickers. Sparking a little joy, one sticker at a time. #restorefundingforsciencenow

I am so glad to be working and living in a bikeable city with public transit. HOWEVER: I remain equally amused and annoyed at the railroad crossings in the middle of downtown Chicago. #urbandesignfails #whyaretrainssoslow
