Dr. Nonterah's new book is full of practical, realistic and motivational advice for someone looking to pivot into a non-academic role.

I can't wait to start putting her recommendations to work as I transition from my #PhD into my own #medcomms and #sciencewriting career.

Documenting achievements isn't bragging Why I always write about my achievements in grad school and how it's saved my mental health

#Gradschool will drive you crazy, especially if you only focus on the negative. In this week's #Substack I opened up a bit about my experience navigating self-doubt & imposter syndrome during my PhD. If you feel similarly, I encourage you to read it πŸ«‚πŸ’•

There's perks to going straight to a PhD, like becoming a doctor at 27 😎 This also means I've spent almost my entire 20s in school. But, it's been a wild ride! Countdown begins...! #gradschool #stem #phd #diml #phdlife #academicsky #boricua #phdcandidate #microbephd

Gut Inflammation Disrupts Hormone Signals and the Brain Reproductive hormones in male mice are susceptible to gut inflammation during early life.

I interviewed a professor at the University of British Columbia about her recent work showing that inflammation during early life can lead to disruptions in the endocrine system and the microbiota.

Absolutely! I didn't even know research was a career option until my sophomore year of college. That's why I think it's so important to help high schoolers learn about STEM early! :) It really sets them up for success
