CFO
Nirvika Rastogi

Email: nirvika.rastogi@duke.edu
Nirvika Rastogi is a 2nd year PhD student in the Velmeshev lab. I am happy to support my peers and if nothing, be a friendly face! Her research focuses on finding functional epigenomic targets for Down Syndrome in neural organoids. Her primary duty as CFO is to aid the rest of the executive board and the committee chairs in realizing their goals by acquiring and approving funding. In the moments I’m not chronically online, I enjoy dancing, wine tastings, yoga and volunteering for communities close to my heart.
CTO/Outreach
Noah Campbell

Email: noah.s.campbell@duke.edu
Noah is a second-year PhD student in Dr. Tatiana Segura’s lab. Their research primarily focuses on the development of anti-inflammatory biomaterials for regenerative medicine and sustained gene delivery in wound healing. Noah was previously a first-year representative for BEPSA and now both serves on the Outreach Committee and works as the Chief Technical Officer to best communicate and reflect BEPSA’s activities and events. Outside of work, Noah enjoys event and street photography, longboarding, and live music.
Committee Chairs
Events Co-Chair
Sophie Shi

Email: sophie.shi@duke.edu
Sophie is a third-year PhD student in T.Dunn Lab. Her research focuses on behavioral study in motor-related neural diseases. She uses deep-learning tools to quantitatively assess behavioral deficits in stroke, enabling sensitive and high-throughput investigation of preclinical treatment. Her role as an event co-chairs is to hold fun events and help organize the recruitment for the department. Outside of work, she really enjoys rock-climbing, crafting, baking, making vlogs, exploring good food… – anything that is fun and refreshing!
Events Co-Chair
Kate Katsouleas

Email: kate.katsouleas@duke.edu
Kate is a second-year PhD student in the Gerecht Lab studying vascular tissue engineering. Her research involves the use of vascular micro physiological systems (MPS) to investigate molecular mechanisms driving ECM dysregulation in arterial disease. As events chair of BEPSA, she is excited to organize events that serve the BME community, both socially and professionally, and foster opportunities to for greater interaction among BME peers. Outside of lab, she loves attending bar trivia, watching movies, hiking, and grabbing coffee.
Outreach Co-Chair
Kat Turk

Email: kathryn.turk@duke.edu
Kat is a third-year PhD student in the Grill Lab, studying peripheral nerve stimulation. Her research includes human, animal and computational studies to understand on and off target tradeoffs and design more effective therapies. Her role as outreach chair involves organizing community-centered events including blood drives, collaboration with local community centers, and educational opportunities with local educational groups. When not in the lab, she enjoys gardening, camping, live music and knitting.
Resources Chair
Sophia Colmenares

Email: sophia.colmenares@duke.edu
Sophia is a second-year PhD student in Daniel Reker's lab. Her research focuses on applying machine learning to investigate how molecular interactions influence drug metabolism. In her free time, she likes to try new sports, taste new caffeinated beverages, and play with her two cats.
First-Year Officers
First-Year Representative
Alexander Armstrong

Email: alexander.armstrong@duke.edu
Alexander is a first-year PhD student in John Hickey's lab. His research focuses on tissue engineering using a novel screening platform that incorporates biomaterials and spatial proteomics technologies. As 1st-year representative, Alexander coordinates events for his cohort to grow comfortable and confident in their new life as a PhD student at Duke BME. Outside of lab, Alexander enjoys playing soccer, enjoying time with friends, and cooking.
First-Year Representative
Emilie Jacobus

Email: emilie.jacobus@duke.edu
Emilie is a first-year student in the Gersbach Lab. Her research aims to develop a CRISPR-based epigenetic therapy for Prader-Willi syndrome. Her role as one of the first-year reps is to plan events for her cohort, including the Adulting 101 series. In her free time she enjoys seeing live music, cooking, and hiking.
