Lab Alumni

  • Edom Seyoum, MS

    Former Research Assistant II

    Edom had assisted with maintaining our mouse colony and optimized antibodies for detection of transcription factors during ENS development.  She has moved on to graduate school at Baylor.  We miss you Edom!!

  • Helen Yang

    Former Undergraduate Research Assistant

    Helen developed vectors for in vitro and in vivo manipulation of genes in developing enteric neural progenitors.  She is a great molecular biologist and excelled at keeping things on track for us in the lab.  She is now off to medical school in New Jersey!  Miss ya Helen!

  • Justin Avila

    Former Neuroscience PhD Program

    Justin has moved to postdoctoral work at the Stowers Research Institute. 

  • Kathryn Spears

    Former Undergraduate Research Assistant

    Kate was quantifying effects of mutations in the Type 3 Serotonin Receptor (Htr3a) on development and differentiation of pelvic ganglia neurons that innervate the bladder.  Kate has moved to the WashU MSTP - so proud of you!!

  • Aaron May, Ph.D.

    Former Postdoctoral Fellow
    Medicine / Division of Genetic Medicine

    Aaron headed the ENSMap effort to derive a global gene expression atlas of human enteric ganglia.  He has now taken on the new role of Senior Bioinformaticist at FluidBio
     

  • Karen Deal

    Former Research Specialist

    Karen worked with our team and generated amazing images that show how neural progenitors colonize the lower urinary tract during development.  Karen retired from research in 2022.  We miss you Karen and hope those grand babies are keeping you busy!

  • K. Elaine Ritter

    Graduate Student
    Neuroscience PhD Program

    Elaine completed her thesis work on the role of Htr3a in bladder innervation and function.  She is now working in a postdoctoral position with Adam Durbin at St. Jude's Research Hospital in Memphis, TN. 

  • Makenzie completed her undergrad honors thesis with us and has moved on to medical school at Duke University.  Way to go Makenzie!!

  • Melissa A. Musser

    Graduate Student
    Medical Scientist Training Program

    Melissa used mouse models during her Ph.D. studies to analyze lineage diversification in the enteric nervous system and determine how this relates to gastrointestinal dysmotility and variability in Hirschsprung patient phenotypes.  Melissa matched to Boston Children's Hospital for her residency training in Peds GI and is now in a Faculty position after completing her Fellowship.  Congrats Muss!!

  • Jenna Brown

    Former Research Assistant

    Jenna worked with us for a short while before retiring from research to start her family.  She was using mouse models to map neuromodulatory cells in relation to developing innervation in the lower urinary tract using a variety of flourescent transgenes and Cre lineage drivers. 

  • Anoop Chandrashekar

    Former Undergraduate Research Assistant

    Anoop graduated from Vanderbilt with highest honors and is now in medical school at Vanderbilt.  Congratulations Anoop!!  We miss you - stop by any time. 

  • Meena Halaka

    Former Research Assistant

    Meena had been characterizing novel alleles taht disrupt development and function of the enteric nervous system.  Meena entered medical school at Saint George’s University School of Medicine. 

  • Jessica Do

    Former Research Assistant

    Jessica let our group to attend Maharry medical school and is now in Pediatric residency at Stanford!  Way to go JD!!

  • Kate Jones

    Former Undergraduate Research Assistant

    During her time with our team, Kate worked to define genome sequence variants that affect ENS development.  Kate graduated from medical school at Temple University and completed her surgery residency at Lankenau Medical Center.  She is pursuing research as a Post Doctoral  Fellow in the Surgical Oncology Research Training Program at the University of Pennsylvania.  Way go Kate!!
