• NICE TO MEET YOU!

    I'M ALEX

     

     

     

     

     

    PhD Student at NYU

    brain evolution

    neurological disorders

    sex differences in the brain

    gene expression

  • What I Do

    I'm interested in the evolution of sex differences in primate cognition, neuroanatomy, and gene expression, and how these relate to the emergence of human neurological disorders. My dissertation will address this topic through both broad comparative analyses and targeted within-species studies. I will be considering multiple levels of brain organization, including functional brain region volumes, sulcal morphology, and gene expression.

     

    Besides writing R code and looking at brains all day... I'm a passionate Teaching Assistant, and I mentor some wonderful ladies (who are sure to be future STEM leaders). Kimberly and I worked together to get her a DART research grant, and she just got accepted into the Teacher's College of Columbia! Talar is an aspiring engineer, avid Science Fair winner, and wonderful writer!

     

    I am thankful for every day spent learning something new. Leaving Wall Street was the best decision I've ever made.
