  • Alex Bashore, B.S., PhD

    • Postdoctoral Research Scientist

    I studied lipoprotein metabolism during my PhD training at Wake Forest University. My project focused on investigating the role of hepatocyte ATP-binding cassette transporter A1 (ABCA1) in high density lipoprotein metabolism. The key research skills I acquired during my training were fast protein liquid chromatography (FPLC), high performance liquid chromatography (HPLC), incorporating radiolabels into lipoproteins for metabolic studies, in vitro and in vivo HDL functional assays, and murine handling and breeding.

    I joined the Reilly lab in 2019 as a Postdoctoral Researcher. My research focuses on identifying common and rare monocyte subpopulations using single cell RNAseq, and how these subpopulations differ between healthy individuals and individuals with different cardiovascular disease risk states (e.g., cigarette smoking, diabetes, hyperlipidemia).

    Research Summary (<200 words): 

    Leila completed her doctoral studies in immunology and infectious disease at Harvard University in the lab of Dr. Dyann Wirth, focusing on biochemical and structural characterization of enzymes in the Plasmodium falciparum malaria parasite’s pyrimidine biosynthetic pathway. She completed a postdoctoral fellowship in the lab of Dr. David Fidock at Columbia University, undertaking training in malaria parasite genetic manipulation and genomic analysis to identify drug resistance mechanisms. In Dr. Reilly’s group, Leila switched out of the lab and became a program manager. Her role includes helping to support and shape research, grants, and manuscripts.

  • Johana Coronel, Ph.D.

    • Post Doctoral Research Scientist

    Education and Training:

    Johana completed her doctoral studies at the University of Illinois at Urbana-Champaign. Her research focused on evaluating the role of stored β-carotene as a potential substrate for β-carotene 15, 15’-dioxygenase (BCO1) in the adipose tissue as a therapeutic target against obesity and atherosclerosis. In 2022, Johana joined the Reilly lab as a Postdoctoral Research Scientist. Her research focuses on determining the role of smooth muscle-derived cells in plaque stability during atherosclerosis regression.

    Prior to joining the Reilly lab I completed a Sarnoff Cardiovascular Research Fellowship in the lab of Dr. Peter Libby at Brigham and Women's Hospital, where my research focused on the effect of neutrophil extracellular traps on endothelial cell activation and thrombogenicity in coronary plaque erosion. I am currently a cardiology fellow at Columbia University Irving Medical Center, working with Dr. Reilly's group since 2022. My research focuses on the role of defective base excision repair and DNA damage in modulating smooth muscle cell phenotype switching in atherosclerosis. I am also interested in computational approaches to integrating large-scale human GWAS data with single cell RNA-seq to guide discovery of novel pathways in human coronary disease.
