Karan Kataria

Karan Kataria is a graduate from the college of education at Michigan State University, East Lansing, majoring in Kinesiology, with a minor in Exercise Physiology. Since his first anatomy class in High-School Karan knew he wanted to pursue a career that allowed him to be a lifelong learner of the sciences, while also giving him the opportunity to help others. Throughout college Karan has TA’d and tutored for various anatomy classes. Furthermore he worked with read to succeed to tutor at risk elementary students. He also had the opportunity to work as an undergraduate researcher under Dr. Pamela Harding at the Henry Ford Hypertension and vascular research lab. In fall of 2020, he founded the Michigan State chapter of the Brain Exercise Initiative. Upon graduating, he joined the National Executive Committee of BEI and is currently taking his gap year applying to medical school.

Shiva Areff

Shiva Areff is a recent graduate of the University of California, Santa Barbara with a major in Biopsychology and a minor in Philosophy. She began her involvement with the Brain Exercise Initiative in 2019, selected as President to begin a Chapter at UCSB. By the time of her departure, UCSB was working with 10 retirement homes and had over 90 volunteers. Although a graduate, she is still heavily involved in research at UCSB as an Undergraduate Researcher in the Miller Memory Lab. She has also volunteered at her local hospital, tutored her peers in STEM classes, and fulfilled leadership roles in other school organizations. Her passions involve helping others and understanding how brain mechanisms and circuitry translate into human behavior. This led her to pursue a path in medicine, as she currently takes a gap year in preparation for applying to Medical Schools.

Yousif Jafar

Northern West Coast Region

Yousif Jafar is a fourth year undergraduate studying Neuroscience at the University of California, Los Angeles. From a young age, Yousif has been intrigued by the limitless capabilities of the human brain, and this has inspired his current trajectory and career path. It began with shadowing a neurologist, understanding the intricacies of the human brain. As he progressed through his undergraduate career, his interests only grew more, and he began to conduct research at both UCI and UCLA. As an undergraduate researcher at the Akbari Lab and the Wassum Lab, Yousif has been able to understand the clinical applications of neuroscience and the neurocircuitry involved in certain behaviors. Yousif continues to grow alongside the Brain Exercise Initiative, starting his journey as a volunteer for the UCLA chapter, Financial Director, and now a member of the National Executive Committee.


Cole Woulbroun

Northeast Region

Cole Woulbroun oversees the Northeastern BEI Chapters.  He is a rising third-year undergraduate at the University of California, Los Angeles (UCLA) majoring in Molecular, Cell, and Developmental Biology and looking ahead to graduate school after college.  With a 4.0 cumulative GPA, Cole has worked as an undergraduate researcher in the Jones Lab during his 1st and 2nd years, conducting literature review and data analysis projects on the aging midgut of Drosophila melanogaster.  The midgut, in a similar fashion to multiple human tissues, undergoes an age-related expansion of resident, multipotent stem cells, which in this case are intestinal stem cells (ISCs).  Starting late in his second year, Cole has also had the opportunity to work in the Hartenstein Lab.  Here, he will be assessing the interactome of neuroglian, a septate-junction protein that helps drive age-related ISC expansion, and changes to the protein in glia of the aged Drosophila brain.  His studies of the Drosophila midgut and ISCs continued in the summer of 2021, where he worked as a student intern at UCSF.  Reflective of his graduate school aspirations, Cole is a reviewer on the UCLA Undergraduate Science Journal, an annual journal consisting of articles written and reviewed by UCLA undergraduates.
