Jade Alvarez

Jade Alvarez, B.S.

Jade Alvarez is originally from the Dominican Republic. She received her Bachelor of Science in Biology from Rowan University in 2019 and will earn her Master’s in Biology from Towson University in summer, 2021. During her undergraduate experience, Jade was awarded a NASA-sponsored fellowship which allowed her to join Dr. Michael Henry’s lab at the Rowan University Graduate School of Biomedical Sciences during the summer of 2017. There, Jade investigated dysfunctions in the mitochondrial genome that are linked to mitochondrial diseases. Her desire to engage in a full-time research experience led me to pursue an M.S. degree at Towson University in the fall of 2019. Captivated by the elaborate hijacking mechanisms employed by certain viruses Jade joined Dr. Barry Margulies’ lab where she studies the interaction between two proteins that may aid in viral egress during Human Cytomegalovirus infection. Throughout her time as a Master’s student, Jade also became very intrigued about the field of cancer immunology although her fascination for viruses remains. Jade’s research interests in further understanding viral-host interactions and navigating the field of cancer immunology urged her to pursue further training. Jade is thrilled to begin her journey as a graduate student in the Pathobiology program at Johns Hopkins School of Medicine where she is hoping to continue her research and professional training. Outside of academics and research, Jade enjoys traveling and exercising. She also enjoys mentoring and advocating for younger students of underrepresented backgrounds who want to pursue careers in STEM.
